Laboratory tests for evaluating the individual's clotting mechanism.
The process of the interaction of BLOOD COAGULATION FACTORS that results in an insoluble FIBRIN clot.
The time required for the appearance of FIBRIN strands following the mixing of PLASMA with phospholipid platelet substitute (e.g., crude cephalins, soybean phosphatides). It is a test of the intrinsic pathway (factors VIII, IX, XI, and XII) and the common pathway (fibrinogen, prothrombin, factors V and X) of BLOOD COAGULATION. It is used as a screening test and to monitor HEPARIN therapy.
Use of a thrombelastograph, which provides a continuous graphic record of the physical shape of a clot during fibrin formation and subsequent lysis.
Hemorrhagic and thrombotic disorders that occur as a consequence of abnormalities in blood coagulation due to a variety of factors such as COAGULATION PROTEIN DISORDERS; BLOOD PLATELET DISORDERS; BLOOD PROTEIN DISORDERS or nutritional conditions.
Clotting time of PLASMA recalcified in the presence of excess TISSUE THROMBOPLASTIN. Factors measured are FIBRINOGEN; PROTHROMBIN; FACTOR V; FACTOR VII; and FACTOR X. It is used for monitoring anticoagulant therapy with COUMARINS.
Endogenous substances, usually proteins, that are involved in the blood coagulation process.
A disorder characterized by procoagulant substances entering the general circulation causing a systemic thrombotic process. The activation of the clotting mechanism may arise from any of a number of disorders. A majority of the patients manifest skin lesions, sometimes leading to PURPURA FULMINANS.
Clotting time of PLASMA mixed with a THROMBIN solution. It is a measure of the conversion of FIBRINOGEN to FIBRIN, which is prolonged by AFIBRINOGENEMIA, abnormal fibrinogen, or the presence of inhibitory substances, e.g., fibrin-fibrinogen degradation products, or HEPARIN. BATROXOBIN, a thrombin-like enzyme unaffected by the presence of heparin, may be used in place of thrombin.
Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products.
Starches that have been chemically modified so that a percentage of OH groups are substituted with 2-hydroxyethyl ether groups.
A plasma protein that is the inactive precursor of thrombin. It is converted to thrombin by a prothrombin activator complex consisting of factor Xa, factor V, phospholipid, and calcium ions. Deficiency of prothrombin leads to hypoprothrombinemia.
Constituent composed of protein and phospholipid that is widely distributed in many tissues. It serves as a cofactor with factor VIIa to activate factor X in the extrinsic pathway of blood coagulation.
Agents acting to arrest the flow of blood. Absorbable hemostatics arrest bleeding either by the formation of an artificial clot or by providing a mechanical matrix that facilitates clotting when applied directly to the bleeding surface. These agents function more at the capillary level and are not effective at stemming arterial or venous bleeding under any significant intravascular pressure.
An antiphospholipid antibody found in association with systemic lupus erythematosus (LUPUS ERYTHEMATOSUS, SYSTEMIC;), ANTIPHOSPHOLIPID SYNDROME; and in a variety of other diseases as well as in healthy individuals. In vitro, the antibody interferes with the conversion of prothrombin to thrombin and prolongs the partial thromboplastin time. In vivo, it exerts a procoagulant effect resulting in thrombosis mainly in the larger veins and arteries. It further causes obstetrical complications, including fetal death and spontaneous abortion, as well as a variety of hematologic and neurologic complications.
An enzyme formed from PROTHROMBIN that converts FIBRINOGEN to FIBRIN.
A clinical condition resulting from repeated physical and psychological injuries inflicted on a child by the parents or caregivers.
The process which spontaneously arrests the flow of BLOOD from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements (eg. ERYTHROCYTE AGGREGATION), and the process of BLOOD COAGULATION.
The transfer of blood components such as erythrocytes, leukocytes, platelets, and plasma from a donor to a recipient or back to the donor. This process differs from the procedures undertaken in PLASMAPHERESIS and types of CYTAPHERESIS; (PLATELETPHERESIS and LEUKAPHERESIS) where, following the removal of plasma or the specific cell components, the remainder is transfused back to the donor.
The techniques used to draw blood from a vein for diagnostic purposes or for treatment of certain blood disorders such as erythrocytosis, hemochromatosis, polycythemia vera, and porphyria cutanea tarda.
Activated form of factor X that participates in both the intrinsic and extrinsic pathways of blood coagulation. It catalyzes the conversion of prothrombin to thrombin in conjunction with other cofactors.
Agents that prevent clotting.
Heat- and storage-stable plasma protein that is activated by tissue thromboplastin to form factor VIIa in the extrinsic pathway of blood coagulation. The activated form then catalyzes the activation of factor X to factor Xa.
Storage-stable glycoprotein blood coagulation factor that can be activated to factor Xa by both the intrinsic and extrinsic pathways. A deficiency of factor X, sometimes called Stuart-Prower factor deficiency, may lead to a systemic coagulation disorder.
The number of PLATELETS per unit volume in a sample of venous BLOOD.
Storage-stable blood coagulation factor acting in the intrinsic pathway. Its activated form, IXa, forms a complex with factor VIII and calcium on platelet factor 3 to activate factor X to Xa. Deficiency of factor IX results in HEMOPHILIA B (Christmas Disease).
Activated form of factor VII. Factor VIIa activates factor X in the extrinsic pathway of blood coagulation.
A fibrin-stabilizing plasma enzyme (TRANSGLUTAMINASES) that is activated by THROMBIN and CALCIUM to form FACTOR XIIIA. It is important for stabilizing the formation of the fibrin polymer (clot) which culminates the coagulation cascade.
The residual portion of BLOOD that is left after removal of BLOOD CELLS by CENTRIFUGATION without prior BLOOD COAGULATION.
The time required by whole blood to produce a visible clot.
A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.
Activated form of factor XI. In the intrinsic pathway, Factor XI is activated to XIa by factor XIIa in the presence of cofactor HMWK; (HIGH MOLECULAR WEIGHT KININOGEN). Factor XIa then activates factor IX to factor IXa in the presence of calcium.
Blood-coagulation factor VIII. Antihemophilic factor that is part of the factor VIII/von Willebrand factor complex. Factor VIII is produced in the liver and acts in the intrinsic pathway of blood coagulation. It serves as a cofactor in factor X activation and this action is markedly enhanced by small amounts of thrombin.
The natural enzymatic dissolution of FIBRIN.
The taking of a blood sample to determine its character as a whole, to identify levels of its component cells, chemicals, gases, or other constituents, to perform pathological examination, etc.
The number of LEUKOCYTES and ERYTHROCYTES per unit volume in a sample of venous BLOOD. A complete blood count (CBC) also includes measurement of the HEMOGLOBIN; HEMATOCRIT; and ERYTHROCYTE INDICES.
Bleeding or escape of blood from a vessel.
Substances, usually endogenous, that act as inhibitors of blood coagulation. They may affect one or multiple enzymes throughout the process. As a group, they also inhibit enzymes involved in processes other than blood coagulation, such as those from the complement system, fibrinolytic enzyme system, blood cells, and bacteria.
Agents that cause clotting.
A plasma alpha 2 glycoprotein that accounts for the major antithrombin activity of normal plasma and also inhibits several other enzymes. It is a member of the serpin superfamily.
A vitamin-K dependent zymogen present in the blood, which, upon activation by thrombin and thrombomodulin exerts anticoagulant properties by inactivating factors Va and VIIIa at the rate-limiting steps of thrombin formation.
Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor V accomplishes this by forming a complex with factor Xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor V leads to Owren's disease.
Activated form of factor IX. This activation can take place via the intrinsic pathway by the action of factor XIa and calcium, or via the extrinsic pathway by the action of factor VIIa, thromboplastin, and calcium. Factor IXa serves to activate factor X to Xa by cleaving the arginyl-leucine peptide bond in factor X.

Values of three coagulation screening tests of precolostral calves. (1/893)

Prothrombin times, partial thromboplastin times and platelet counts were performed to determine normal values and to screen for coagulation defects of precolostral calves. The precolostral calves were in two groups: one group of a few calves was tested two years before the second larger group. The results for both groups were similar. The tests were performed on postcolostral calves and on mature cows to compare their values with those of precolostral calves. The mean values of prothrombin times and partial thromboplastin times of precolostral calves in the first group were 18.8 seconds and 54.8 seconds respectively. The mean values of prothrombin times and partial thromboplastin times of precolostral calves in the second group were 18.8 seconds and 50.8 seconds respectively. The mean platelet count was 422,400/cmm for the first group and 482,800/cmm for the second group.  (+info)

Compound-heterozygous mutations in the plasminogen gene predispose to the development of ligneous conjunctivitis. (2/893)

Homozygous type I plasminogen deficiency has been identified as a cause of ligneous conjunctivitis. In this study, 5 additional patients with ligneous conjunctivitis are examined. Three unrelated patients (1 boy, 1 elderly woman, and 1 man) had plasminogen antigen levels of less than 0.4, less than 0.4, and 2.4 mg/dL, respectively, but had plasminogen functional residual activity of 17%, 18%, and 17%, respectively. These subjects were compound-heterozygotes for different missense mutations in the plasminogen gene: Lys19 --> Glu/Arg513 --> His, Lys19 --> Glu/Arg216 --> His, and Lys19 --> Glu/Leu128 --> Pro, respectively. The other 2 patients, a 14-year-old boy and his 19-year-old sister, who both presented with a severe course of the disease, exhibited plasminogen antigen and functional activity levels below the detection limit (<0.4 mg/dL and <5%, respectively). These subjects were compound-heterozygotes for a deletion mutation (del Lys212) and a splice site mutation in intron Q (Ex17 + 1del-g) in the plasminogen gene. These findings show that certain compound-heterozygous mutations in the plasminogen gene may be associated with ligneous conjunctivitis. Our findings also suggest that the severity of clinical symptoms of ligneous conjunctivitis and its associated complications may depend on the amount of plasminogen functional residual activity.  (+info)

Comparison of the antithrombotic effect of PEG-hirudin and heparin in a human ex vivo model of arterial thrombosis. (3/893)

Polyethylene glycol (PEG)-hirudin is a derivative of hirudin with a long plasma half-life. We have compared the efficacy of PEG-hirudin with unfractionated heparin (UH) in preventing arterial thrombosis. Arterial thrombus formation was induced ex vivo in 12 healthy human volunteers by exposing a tissue factor-coated coverslip positioned in a parallel-plate perfusion chamber to flowing nonanticoagulated human blood drawn directly from an antecubital vein at an arterial wall shear rate of 2600 s-1 for 3.5 minutes. PEG-hirudin, UH, or saline (as control) were administered ex vivo through a heparin-coated mixing device positioned proximal to the perfusion chamber. Platelet and fibrin deposition was quantified by immunoenzymatic measure of the P-selectin and D-dimer content of dissolved plasmin-digested thrombi, respectively. UH was administered to a plasma concentration of 0.35 IU/mL. This concentration prolonged the activated partial thromboplastin time from 32+/-1 seconds to 79+/-4 seconds (P<0.01). UH did not significantly prevent platelet deposition. However, fibrin deposition was reduced by 39% (P<0.05). PEG-hirudin in plasma concentrations of 0.5, 2.5, and 5 microg/mL prolonged the activated partial thromboplastin time to 48+/-2, 87+/-4, and 118+/-4 seconds, respectively. In contrast to UH, PEG-hirudin prevented both platelet and fibrin deposition in a dose-dependent manner with a >80% reduction at 5 microg/mL (P<0.01). Furthermore, the plasma level of PEG-hirudin required to significantly prevent fibrin deposition (0.5 microg/mL) corresponded to a much shorter prolongation of activated partial thromboplastin time (48+/-2 seconds) than that needed for UH (79+/-4 seconds). Thus, our results are compatible with the view that thrombin is greatly involved in recruitment of platelets in evolving thrombi, and that PEG-hirudin is an effective agent for preventing arterial thrombosis in a human ex vivo experimental model.  (+info)

Abnormalities in liver function and coagulation profile following the Fontan procedure. (4/893)

OBJECTIVE: To investigate liver function and coagulation disorders in patients with a Fontan circulation at different time intervals after surgery. DESIGN: Retrospective analysis of clinical data and cross sectional study relating liver function and coagulation profile to time since surgery, in 28 surviving patients after the modified Fontan procedure. PATIENTS: 20 patients (71%) with atriopulmonary anastomosis, seven (25%) with atrioventricular anastomosis, and one (4%) with total cavopulmonary connection. Follow up ranged from 2.0 to 21.8 years (mean 11.1). RESULTS: Abnormal liver function tests, mainly reflecting cholestasis, were present in 21 patients who had a significantly longer follow up (p < 0.01). Protein synthesis was normal in almost all patients. Coagulation profile showed abnormalities in 22 patients. "Procoagulant" abnormalities-that is, decreased plasminogen and protein C activity-were found in 11 and five patients, respectively. The extent of these abnormalities was less in patients with a longer follow up. Anticoagulant abnormalities were factor V deficiency in 16 patients and factor VII deficiency in 17, resulting in a prolonged prothrombin time in 19 patients. Thirteen patients had both pro- and anticoagulant abnormalities. A prethrombotic state was present in five patients, with a significantly longer mean time interval since surgery (p = 0.05). Thus, although the individual procoagulant indices decreased with increasing time intervals since surgery, a prethrombotic state was found particularly in patients with a long term follow up. CONCLUSIONS: Mild cholestasis was mainly present in Fontan patients with a long duration of follow up. Along with laboratory procoagulant abnormalities indicating a prethrombotic state, anticoagulant abnormalities were also present. The coagulation profile varied at different time intervals after surgery. Thus detailed evaluation should be performed regularly, and the use of anticoagulants should be considered in every patient. Long term prospective studies are needed to evaluate the individual fluctuations of coagulation profile over time following a Fontan procedure.  (+info)

Comparative characterisation of Russell's viper (Daboia/Vipera russelli) venoms from different regions of the Indian peninsula. (5/893)

Russell's viper (Daboia/Vipera russelli) venom from different regions of India was subjected to chromatographic, electrophoretic, biochemical and immunological analysis. The elution profiles from ion-exchange chromatography and protein banding pattern from SDS-PAGE showed a significant variation in the constituents of venoms. The acidic proteins are found to be predominant in the venoms of eastern and western regions while basic proteins are the major contributors of the northern and southern regional venoms. The major variation of phospholipases A(2) in the venom samples of India may be described as: southern regional venom is rich in basic, toxic PLA(2) while this activity showed a dramatic decrease as one moves towards west, north and eastern regions of India. In addition, the caseinolytic, TAME-hydrolytic, anticoagulant, oedema-inducing and haemorrhagic activities of the venoms have also varied from one region to another. The muscle specimens of mice injected with venoms of different regions showed variable change in the muscle fibre damage and cell morphology. The eastern regional venom is most lethal among all the venoms. The lethal potencies for four regional venoms vary as: eastern>western>southern>northern. The polyclonal antibodies prepared against the venom of southern region showed cross-reaction with the venoms of other regions, but the extent of cross-reaction and diffusion patterns are different. However, the polyclonal antibodies prepared against southern regional venom showed no protection against lethal toxicity of other regional venoms.  (+info)

IgG reactivity to phospholipid-bound beta(2)-glycoprotein I is the main determinant of the fraction of lupus anticoagulant activity quenched by addition of hexagonal (II) phase phospholipid in patients with the clinical suspicion of antiphospholipid-antibody syndrome. (6/893)

BACKGROUND AND OBJECTIVE: Autoantibodies to beta(2)-glycoprotein I (beta(2)-GPI) and/or prothrombin (FII) have been involved in the expression of lupus anticoagulant (LA) activity, an in vitro phenomenon associated with an increased risk of arterial and/or venous thromboembolic events. However, LA activity sustained by anti-FII antibodies has a much weaker association with thrombosis than LA activity sustained by anti-beta(2)-GPI antibodies. Because assays aimed at detecting LA activity are now commercially available, we evaluated the relative sensitivity to anti-FII and anti-beta(2)-GPI antibodies of a commercial LA assay in a consecutive series of patients with the clinical suspicion of anti-phospholipid antibody (APA) syndrome. DESIGN AND METHODS: One hundred and ten consecutive patients with the clinical suspicion of APA syndrome (primary in 39) and 36 healthy controls were evaluated for the presence of LA activity (LA, Staclot, Stago), anticardiolipin antibodies (Quanta Lite aCL IgG, IgM, Inova Diagnostics), and IgG binding to solid-phase and/or phospholipid (PL)-bound beta(2)-GPI and FII by ELISA assays developed an optimized in our laboratory. Odds ratios for the association of IgG binding activity with LA and the aCL IgG status were calculated. In LA patients, dependency of LA potency (as assessed by clotting time prolongation in absence or presence of hexagonal phospholipid) on autoantibody titers was analyzed by the generalized linear model. Total IgG fractions were purified from selected patients to evaluate their ability to inhibit prothrombin activation at low FII concentration. RESULTS: Anticardiolipin antibodies (aCL) of the IgG or IgM type were found in 64 and 23 patients and LA activity in 49 patients. Anti-beta(2)-GPI and anti-FII (solid-phase and PL-bound) IgG titers exceeding by more than 3 standard deviations the mean values observed in control subjects were found in 46 and 47 patients and in 56 and 30 patients respectively, with the highest titers detected in the subgroup of patients with both LA and aCL IgG. The relative risk of LA for patients free of anti-FII and/or anti-beta(2)-GPI IgG was 0.03 after stratification for the aCL IgG status. Anti-beta(2)-GPI (solid-phase and PL-bound) IgG (RR 34.4 and 12.6) and anti-FII (solid-phase) IgG (RR 6.33) were all associated with LA activity. However, when taking into account co-existence of anti-FII and anti-beta(2)-GPI IgG in the same patients, the relative risk of LA for patients with isolated anti-FII IgG (solid-phase and/or PL-bound) was 0.50, whereas it ranged from 4.24 to 8.70 for all the antibody combinations including anti-beta(2)-GPI IgG. Anti-beta(2)-GPI (PL-bound) and aCL IgG titers were the only significant predictors of LA potency determined in absence phospholipid (anti-beta(2)-GPI IgG) or in presence of hexagonal phospholipid (aCL IgG). Total IgG fractions purified from 12 patients (6 with anti-FII IgG) did not significantly inhibit factor II activity up to a 150-fold molar excess. INTERPRETATION AND CONCLUSIONS: These results highlight the high prevalence of anti-FII and anti-beta(2)-GPI IgG in patients with the clinical suspicion of APA syndrome and particularly in the subgroup of patients with LA activity. The fraction of LA activity which can be quenched by addition of hexagonal phospholipid is, however, only dependent on IgG directed to PL-bound beta(2)-GPI. Other antibodies associated with anticardiolipin IgG may explain residual clotting time prolongation observed in the presence of hexagonal phospholipid.  (+info)

Response of vitamin K status to different intakes and sources of phylloquinone-rich foods: comparison of younger and older adults. (7/893)

BACKGROUND: Phylloquinone, found in dark-green vegetables and certain plant oils, is the primary dietary source of the fat-soluble vitamin K. Limited data suggest that the relative bioavailability of phylloquinone from vegetables is lower than that from a supplement. This finding is relevant to the maintenance of optimal vitamin K status. OBJECTIVE: The objective of this study was to compare, in younger and older adults, the relative bioavailability of phylloquinone from a vegetable with that of a fortified oil. DESIGN: In a crossover design with three 15-d residency periods in a metabolic unit, younger and older men and women (n = 36) consumed a mixed diet containing 100 microg phylloquinone/d. During 2 residency periods, the mixed diet was supplemented for 5 d with either broccoli (377 microg phylloquinone/d; broccoli diet) or phylloquinone-fortified oil (417 microg/d; oil diet). The relative bioavailability of phylloquinone was defined by the difference in plasma phylloquinone, percentage serum undercarboxylated osteocalcin (%ucOC), and urinary gamma-carboxyglutamic acid in response to 5 d of supplementation. RESULTS: For both younger and older adults, plasma phylloquinone concentrations were higher (P < 0.001) and %ucOC values were lower (P = 0.001) after the broccoli and oil diets than after the mixed diet only. Overall, the response to broccoli supplementation was not significantly different from the response to the fortified oil in either age group. Urinary gamma-carboxyglutamic acid did not change in response to supplementation. CONCLUSIONS: There was no significant difference in the relative bioavailability of phylloquinone, as evidenced by the lack of a significant difference in plasma phylloquinone and %ucOC between the 2 groups after either the broccoli or oil diets for younger and older adults.  (+info)

Laboratory evaluation of difenacoum as a rodenticide. (8/893)

The efficacy of difenacoum as a new anticoagulant rodenticide was evaluated by blood coagulation studies and laboratory feeding tests using warfarin-resistant and non-resistant common rats (Rattus norvegicus), ship rats (R. rattus) and house mice (Mus musculus). Prothrombin assays indicated that the compound had as marked an activity with warfarin-resistant common rats as coumatetralyl had with non-resistant animals. Feeding tests confirmed that 0-005% would be a near-optimal concentration for field use, although there was some evidence of unpalatability. Results with ship rats and house mice were less favourable. Trials with enclosed colonies of warfarin-resistant mice confirmed the laboratory finding that although difenacoum was more effective than all other currently used anticoagulants, it was unlikely to give complete control. It is concluded that difenacoum is a valuable new rodenticide, especiaaly for controlling warfarin-resistant common rats.  (+info)

Traditional coagulation tests are included in emergency guidelines for management of patients on direct oral anticoagulants (DOACs) who experience acute bleeding or require surgery. We determined the ability of traditional coagulation tests and fast whole blood thromboelastography (ROTEM®) to screen for anticoagulation activity of dabigatran and rivaroxaban as low as 30 ng/mL. One hundred eighty-four citrated blood samples (75 dabigatran, 109 rivaroxaban) were collected from patients with non-valvular atrial fibrillation (NVAF), to perform screening tests from different manufacturers, (diluted, D) PT, aPTT, TT and ROTEM®. The activity of DOACs was quantitatively determined by clot detection assays: Hemoclot DTT and DiXaI test (Biophen), on CS2100 (Siemens). The clotting time (CT) of INTEM and EXTEM ROTEM® (Werfen) were used as test parameters. Dabigatran, ≥ 30 ng/mL, was accurately detected by five coagulation tests: APTT Actin FSL (93%), PT Neoplastin (93%), APTT Cephascreen, Thromboclotin, and

Background: The concept of developmental hemostasis has been universally accepted. Physiological reference ranges for coagulation tests are available for infants and children of different ages. However, on Oriental children they are rare.. Methods: Results of preoperative activated partial thromboplastin time (APTT) in neonates, infants, children aged 1-18 years and adults with minor elective surgery in a university affiliated hospital were reviewed retrospectively. Plasma activity of factors VIII, IX, XI, XII (FVIII: C, FIX: C, FXI: C, FXII: C) and lupus anticoagulants (LAC) in 47 children with prolonged APTT and 34 adult controls were measured to investigate the causes of prolongation.. Results: Compared with adults, APTT values were prolonged significantly and were age-dependent in children, especially in neonates and infants aged 1-6 months. Mean values for FXII: C and FIX: C in children with prolonged APTT values were significantly lower than those in adults ( ...
Thromboelastography (TEG) is a point-of-care whole blood coagulation monitor which provides information on specific aspects of coagulation including time to production of initial fibrin strands (R-time), time to develop clot (R-time, K-time), rate of fibrin build-up and cross linking (-angle), maximum clot strength (maximum amplitude bMA) and measures of fibrinolysis (decreasing amplitude post-MA). Abnormal TEG data may predict patients who will bleed. Spiess [2] found that TEG correlated well with ACT and coagulation profiles and whilst no coagulation test was consistently abnormal the TEG was the most accurate predictor of bleeding. Ereth studied a Platelet-activated clotting test (PACT HemoSTATUS), ACT and clotting studies, and TEG. Whilst PACT sensitivity and specificity was comparable to conventional coagulation tests in predicting blood loss, TEG was more predictive at both blood loss levels. Essell found that whilst the bleeding time and platelet count had sensitivities similar to the ...

Click the title to purchase the article.. Background:. Viscoelastic tests (VETs) such as thromboelastography, rotational thromboelastography, and the Sonoclot Analyzer assess the entire process of clot formation through dissolution in real-time, and may provide additional therapeutic value to conventional laboratory coagulation tests. With the ability to obtain rapid results and identify specific coagulopathies, VETs has been examined in a variety of clinical scenarios, including cardiac surgery, trauma, obstetric emergencies, and liver transplant. Conclusion: This review provides a summary of clinical trials utilizing VETs in the aforementioned clinical scenarios, and suggests that VETs have demonstrated a capability to identify coagulopathies, utility in guiding algorithms to reduce the amount of transfusions, and a limited ability to predict bleeding events or mortality.1. ...
Thromboelastometry (TEM), previously named rotational thromboelastography (ROTEG) or rotational thromboelastometry (ROTEM), is an established viscoelastic method for hemostasis testing in whole blood. It is a modification of traditional thromboelastography (TEG). TEM investigates the interaction of coagulation factors, their inhibitors, anticoagulant drugs, blood cells, specifically platelets, during clotting and subsequent fibrinolysis. The rheological conditions mimic the sluggish flow of blood in veins. TEM is performed with the ROTEM whole blood analyzer (Tem Innovations GmbH, Munich) and is an enhancement of thrombelastography, originally described by H. Hartert in 1948. While traditional thromboelastography is a global assay for blood clotting disorders and drug effects, TEM is primarily used in combination with appropriate differential assays. They allow testing in the presence of therapeutic heparin concentrations and provide differential diagnostic information to support decisions in ...
A partial thromboplastin time (PTT) test measures how long it takes for a clot to form in a blood sample. A clot is a thick lump of blood that the body produces to seal leaks, wounds, cuts, and scratches and prevent excessive bleeding.. The bloods ability to clot involves platelets (also called thrombocytes) and proteins called clotting factors. Platelets are oval-shaped cells made in the bone marrow. Most clotting factors are made in the liver.. When a blood vessel breaks, platelets are first to the area to help seal off the leak and temporarily stop or slow the bleeding. But for the clot to become strong and stable, the action of clotting factors is required.. The bodys clotting factors are numbered using the Roman numerals I through XII. They work together in a specialized sequence, almost like pieces of a puzzle. When the last piece is in place, the clot develops - but if even one piece is missing or defective, the clot cant form.. The PTT test is used to evaluate the ability of a ...

A portable device for performing coagulation tests on a patients blood. Blood is first drawn from a patient using a lancet. The blood is then supplied to a disposable cuvette placed within the testing device. The blood is drawn into multiple conduits within the cuvette. Each of the conduits contains a dried or lyophilized activation reagent that is rehydrated by the blood. The blood in each of the conduits is then reciprocally moved across a restricted region until a predetermined degree of coagulation occurs. Since the coagulation time is being monitored in multiple conduits, a representation coagulation time for a given sample can be determined. In at least one of the conduits a normalizing control agent is present. The normalizing control agent counteracts any effects of anticoagulants present in the blood sample, thereby allowing the blood sample to have generally normal coagulation characteristics. The normalized blood is tested simultaneously with the untreated blood to provide a reference value

1] A new two-dimensional aerosol bin scheme, which resolves both aerosol size and black carbon (BC) mixing state for BC aging processes (e.g., condensation and coagulation) with 12 size × 10 mixing state bins, has been developed and implemented into the WRF-chem model (MS-resolved WRF-chem). The mixing state of BC simulated by this model is compared with direct measurements over the East Asian region in spring 2009. Model simulations generally reproduce the observed features of the BC mixing state, such as the size-dependent number fractions of BC-containing and BC-free particles and the coating thickness of BC-containing particles. This result shows that the model can simulate realistic BC mixing states in the atmosphere if condensation and coagulation processes are calculated explicitly with the detailed treatment of BC mixing state. Sensitivity simulations show that the condensation process is dominant for the growth of thinly coated BC particles, while the coagulation process is necessary ...

  • Preoperative blood tests showed no abnormalities, and there was no coagulation disorders. (
  • Specifically, TEG is currently being utilized by the Anesthesiology lab to study coagulation disorders in stroke and trauma patients. (
  • The growing prevalence of various blood clotting disorders, such as deep vein thrombosis (DVT), and hemophilia along with rise in aging population across the globe are the significant growth factors for the coagulation testing market. (
  • The major factors that contribute to the growth of the coagulation testing market include increasing prevalence of blood disorders & cardiovascular diseases, rise in geriatric population, high demand for point of care coagulation testing, and technological advancements such as faster and easy-to-use devices with advanced sensors technology. (
  • The global coagulation testing market is expected to witnessing significant growth during the giving forecast period owing to the rising prevalence of the blood disorders. (
  • Although originally developed for the treatment of inhibitor-complicated hemophilia A and B, novel indications for rFVIIa (based on case reports and smaller clinical trials) include use in patients with liver disease, thrombocytopenia, or qualitative platelet dysfunction and in patients with no coagulation disorders who are bleeding as a result of extensive surgery or major trauma. (
  • This test is used to detect the causes of thromboembolism (Blood clotting disorders) and protein -C deficiency. (
  • Delay in treatment can lead to coagulation disorders, with a risk of massive, diffuse bleeding. (
  • Transfuse fresh whole blood or packed red blood cells or whole blood + fresh frozen plasma in the event of massive haemorrhage and/or coagulation disorders. (
  • A blood clotting test, also known as a coagulation blood test, is used to determine how well the blood is able to form blood clots to stop bleeding after the skin has been cut or broken. (
  • The test may be ordered for any number of conditions where a doctor has concerns about the patient's ability to form blood clots. (
  • Results Low levels of platelets in the blood or low levels of fibrin in the blood can inhibit the body's ability to form blood clots. (
  • They help form blood clots to stop bleeding when you have an injury. (
  • You have several different types of clotting factors that are all important for making blood clots. (
  • But normally, clotting factors are turned off, so you don't form abnormal blood clots. (
  • Your blood clots too easily, even without an injury. (
  • This condition may lead to clots that block your blood flow and cause serious conditions, such as heart attack , stroke , or clots in the lungs . (
  • Coagulation factor tests are also used to monitor people who have a known problem with clotting factors or who take medicine called blood thinners to lower the risk of blood clots. (
  • These tests are part of a coagulation study used to determine how quickly a patient's blood clots. (
  • The test gauges coagulation status by measuring elasticity as a small blood sample clots over a few minutes. (
  • These tests avoid the chances of heart attack, thrombosis, and embolism by detecting the presence of blood clots in blood vessels. (
  • Fibrinolysis is a normal body process that keeps naturally occurring blood clots from growing and causing problems. (
  • 1] though a general answer to this question is now obvious, the biochemical mechanisms involved in how the blood coagulates (clots) are complex and varied, and all the intricacies have not yet been explained. (
  • Protein-C has an important role in the regulation of blood clots. (
  • Hence these pathological conditions contribute in formation of frequent blood clots (thrombophilia) and thus these patients are to be monitored since they are at a very high risk of intravascular thrombus formation (thrombosis) leading to complications such as VTE (venous thrombo-embolism), DIC, DVT, pulmonary embolism, stroke, purpura fulminans, death of newborn (neonatal purpura in newborn babies could be a clinical manifestation for the deficiency of APC-Activated Protein-C) etc. (
  • Low molecular weight heparin - An anticoagulant medication (derived from heparin, see 'Unfractionated heparin' below) that is injected in order to prevent blood clots from growing larger and prevent new clots from forming. (
  • Venogram - A less-common test that identifies blood clots in the leg by injecting a special dye into a vein on the foot. (
  • Venous thromboembolism (VTE) - The formation of blood clots in the vein. (
  • Blood clots most often develop deep in leg veins, and symptoms are easily missed. (
  • The medical term for blood clots developing in the large veins of the leg or pelvis is deep vein thrombosis (DVT). (
  • This is because blood clots are generally caused by sluggish blood flow through the vein, usually from sitting in cramped positions for long periods of time. (
  • The last time I flew commercially, I felt the threat of blood clots because there was rough weather and we were kept down in our seats, all of which were overcrowded. (
  • Perform uterine exploration to remove any blood clots or placental fragments and check for absence of uterine rupture. (

  • Pneumococcal antigen tests for serum, urine, and saliva samples have been developed. (
  • Arterial blood gas (ABG) determination (serum pH, arterial oxygen saturation, arterial partial pressure of oxygen and carbon dioxide) - Hypoxia and respiratory acidosis may be present. (
  • On March 6, a routine blood chemistry screen showed elevations of total bilirubin, alkaline phosphatase, gamma glutamyl-transferase, serum glutamic oxalacetic transaminase, and lactate dehydrogenase. (
  • PCR testing for C. burnetii (targeting insertion sequence 1111) in serum returned negative results. (
  • Serum tests for both IgG and IgM antibody to toxoplasmosis will be added to the NHANES 2001 laboratory protocol to obtain the most accurate information available about the prevalence of toxoplasmosis in the U.S. and determine if the rates are changing over time. (
  • The complete blood cell count, coagulation profile, serum electrolyte panel, and renal function test are unremarkable. (
  • Since 1986, when tests for measuring PSA levels in serum were introduced into clinical practice, early diagnosis and management of prostate cancer has been revolutionized, and much has been learned about the strengths and weaknesses of these assays. (
  • His serum sodium (Na) was 128 mEq/L and potassium (K) was 2.8 mEq/L. His urine sediment was bland with no proteinuria and no red blood cells and WBCs. (
  • Exam Items : Serum biochemistry, drug monitoring and serum immunology testing. (
  • More specific tests, such as albumin, liver enzyme tests, and serum protein electrophoresis must be performed to make an accurate diagnosis. (
