A test to detect non-agglutinating ANTIBODIES against ERYTHROCYTES by use of anti-antibodies (the Coombs' reagent.) The direct test is applied to freshly drawn blood to detect antibody bound to circulating red cells. The indirect test is applied to serum to detect the presence of antibodies that can bind to red blood cells.

Rho(D) Immune Globulin
Immunoglobulin preparations used in intravenous infusion, containing primarily IMMUNOGLOBULIN G. They are used to treat a variety of diseases associated with decreased or abnormal immunoglobulin levels including pediatric AIDS; primary HYPERGAMMAGLOBULINEMIA; SCID; CYTOMEGALOVIRUS infections in transplant recipients, LYMPHOCYTIC LEUKEMIA, CHRONIC; Kawasaki syndrome, infection in neonates, and IDIOPATHIC THROMBOCYTOPENIC PURPURA.
Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.
The intra- and inter-assay variation of the indirect mixed antiglobulin reaction test: is a quality control suitable? (1/208)The test most commonly used to detect sperm antibodies is the mixed antiglobulin reaction (MAR), standardized by the World Health Organization. The indirect MAR test detects soluble sperm antibodies in seminal plasma by using healthy donor spermatozoa as antigen. In this study we systematically investigated the influence of donor spermatozoa and the source of sperm antibodies upon the results of the indirect MAR test, and calculated the intra- and inter-assay variations. Using one individual seminal plasma and the same donor semen, results of the indirect MAR test are highly reproducible (low intra-assay variation). Two dimensions of inter-assay variation must be considered: (i) serial ejaculates of an individual donor may be used at different times; (ii) different donors may be applied to identical antibody sources. Donor spermatozoa strongly influenced the results of the indirect MAR test. Using multivariate statistical tests, highly significant main effects between the different donors (P < 0.001) and specific reciprocal effects between donor spermatozoa and seminal plasma samples (P < 0.001) were observed. The high inter-assay variation of the indirect MAR test will lead to incorrect results. There is urgent need of a reliable and reproducible test for sperm antibody detection to improve quality control of the methods. (+info)
A persistent severe autoimmune hemolytic anemia despite apparent direct antiglobulin test negativization. (2/208)BACKGROUND AND OBJECTIVE: Not all cases of autoimmune hemolytic anemia (AIHA) are diagnosed by the direct antiglobulin test (DAT). We present and discuss a simple method of enhancing the sensitivity of the standard DAT. DESIGN AND METHODS: We report the case of a five-month-old child diagnosed with a severe IgG-mediated AIHA, characterized by quick DAT negativization despite clinical worsening. Warm AIHA with negative DAT, possibly due to a low affinity autoantibody, unresponsive to conventional therapy, was hypothesized. RESULTS: The DAT resulted strongly positive with anti-IgG serum using a 4C saline for erythrocyte washing, to reduce the dissociation of the supposed low affinity autoantibody. Very intensive cytoreductive treatment was administered twice until clinical remission was obtained. INTERPRETATION AND CONCLUSIONS: The clinical course of AIHA can be dissociated by the DAT. Since autoantibody-mediated hemolysis with negative DAT rarely occurs, once other causes of high reticulocyte count anemia have been ruled out, the DAT after ice-cold saline washing could be a useful and easy means of corroborating the diagnosis of AHIA, when traditional methods fail.

Posttreatment follow-Up of brucellosis by PCR assay. (3/208)In order to evaluate the usefulness of a peripheral blood PCR assay in the posttreatment follow-up of brucellosis, a cohort of 30 patients was studied by means of blood cultures, rose Bengal, seroagglutination, Coombs' antibrucella tests, and PCR assay at the time of diagnosis, at the end of treatment, and 2, 4, and 6 months later. Of the 29 patients whose PCR assays were initially positive, 28 (96.5%) were negative at the conclusion of the treatment. PCR was positive for the two patients who had relapses and negative for another four who had suspected but unconfirmed relapses. PCR was negative for 98.3% of the follow-up samples from those patients who had a favorable evolution. In conclusion, PCR appears to be a very useful technique, not only for the initial diagnosis of the disease, but also for posttreatment follow-up and the early detection of relapses. (+info)
Relative sensitivity of direct antiglobulin test, antibody's elution and flow cytometry in the serologic diagnosis of immune hemolytic transfusion reactions. (4/208)BACKGROUND AND OBJECTIVE: Current immunohematology practice dictates that serologic diagnosis of immune hemolytic transfusion reactions (IHTR) is based on the finding of a positive post-transfusion direct antiglobulin test (DAT). However, since DAT may fail to detect antibody-coated cells when they constitute a minor population amid a large number of non-sensitized ones, we investigated whether antibody detection in eluates or by flow cytometry is more sensitive than DAT in this context. DESIGN AND METHODS: Ten samples of red blood cells sensitized with allo- or autoantibodies were diluted in non-sensitized red blood cells to final concentrations ranging from 10% to 0.1%. DAT, antibody detection in eluates, and immunofluorescence by flow cytometry were performed on each mixture. RESULTS: DAT failed to detect sensitized cells in all but two cases in that only the 10% dilution yielded a positive DAT. Antibody detection in eluates and by flow cytometry was able to detect up to 1% sensitized cells in most cases. INTERPRETATION AND CONCLUSIONS: Antibody detection in eluates and by flow cytometry is more sensitive than DAT for detecting minor populations of IgG-coated cells. These techniques should be included in the routine investigation of suspected cases of IHTR. (+info)
Allogeneic peripheral blood hematopoietic stem cell transplantation: guidelines for red blood cell immuno-hematological assessment and transfusion practice.Societe Francaise de Greffe de Moelle. (5/208)Allogeneic peripheral blood hematopoietic stem cell transplantation (PBSCT) is presently being evaluated in a French randomized study comparing peripheral blood vs bone marrow. Cases of potentially lethal acute hemolysis have recently been reported after allogeneic PBSCT in the presence of a 'minor' ABO incompatibility. Patients were frequently transfused with recipient-compatible and donor-incompatible RBC and usually did not receive methotrexate in addition to cyclosporin A for graft-versus-host disease (GVHD) prophylaxis. In order to homogenize immuno-hematological (IH) assessment and transfusion practices within our protocol, we made proposals to 25 allo-transplant French centers on the following aspects: pre-inclusion IH assessment, IH exclusion criteria, transfusion rules, post-transplant IH surveillance and treatment of hemolysis. Analysis of responses to our proposals led to the elaboration of guidelines which were approved and implemented by the French Bone Marrow Transplantation Society (SFGM). Pre-inclusion IH testing includes mandatory detection and titration of anti-RBC allo-Ab, as well as titration of anti-A and anti-B Ab. The presence in the donor of an anti-A (group A or AB recipients), anti-B (group B or AB recipients) Ab with a titer >1/32 or the presence of allo-Ab against Rh, Kell, Fya, Fyb, Jka, Jkb, Ss Ag present on recipient RBC is an exclusion criterion for the protocol. ABO and RhD compatibility of RBC blood products with both HSC donor and recipient is mandatory. A similar compatibility is also required for Rh (other than D) and Kell Ag. If not possible, compatibility of RBC blood products with the HSC donor is mandatory. Lastly, guidelines regarding post-transplantation IH follow-up as well as acute hemolysis treatment have been elaborated. The implementation of these guidelines should contribute to enhancing the quality of transfusion practice after PBSCT. Such an approach will be applied to other aspects of transfusion medicine in the setting of HSC transplantation. Bone Marrow Transplantation(2000) 25, 507-512. (+info)
Unrelated umbilical cord blood transplantation in infancy for mucopolysaccharidosis type IIB (Hunter syndrome) complicated by autoimmune hemolytic anemia. (6/208)This report describes unrelated umbilical cord blood transplantation for a 10-month-old infant boy with mucopolysaccharidosis IIB (Hunter syndrome), an X-linked metabolic storage disorder due to deficiency of iduronate sulfatase. Two years after transplant approximately 55% normal plasma enzyme activity has been restored and abnormal urinary excretion of glycosaminoglycans has nearly completely resolved. The boy has exhibited normal growth and development after transplant. Nine months after transplant he developed severe autoimmune hemolytic anemia and required 14 months of corticosteroid treatment to prevent clinically significant anemia. Bone marrow transplantation for Hunter syndrome and post-transplant hemolytic anemia are reviewed. Bone Marrow Transplantation (2000). (+info)
Modification of the immunogenicity and antigenicity of rat hepatoma cells. I. Cell-surface stabilization with glutaraldehyde. (7/208)gamma-Irradiated rat hepatoma cells are immunogenic in syngeneic WAB/Not rats, so that immunized animals are protected against tumour-cell challenge and circulating tumour-specific antibody is produced. Treatment of the immunizing cells with glutaraldehyde at concentrations of 0.001% or greater for 30 min rendered these cells non-protective in tumour-rejection tests and no longer able to induce significant formation of specific antibody. However, tumour-specific antigens were shown to be expressed upon treated cells; they specifically bound tumour-specific antibody from syngeneic immune sera assessed in indirect membrane-immunofluorescence tests. Also, these cells specifically absorbed antibody from immune or tumour-bearer sera, as demonstrated in the indirect membrane-immunofluorescence test or a complement-dependent 51Cr-release test. Alloantigen expression was not influenced by glutaraldehyde treatment, although glutaraldehyde-treated hepatoma cells failed to induce alloantibody formation in KX/Not rats. Polyacrylamide-gel electrophoresis of treated cells, surface-labelled with 125I, indicated that extensive cross-linking of the surface protein occurred as a result of glutaraldehyde treatment. The present findings establish that although the expression of a tumour-specific antigen is necessary for the induction of immuno-protection against tumour-cell challenge, this alone is not a sufficient condition for eliciting tumour immunity.

Poly IC therapy in aleutian disease of mink. (8/208)Twenty-four virgin female aleutian mink were infected with aleutian disease agent and after 24 hours, 12 of these were treated with a course of polyinosinic acid-polycytidilic acid (Poly IC) injections. After six weeks the gammaglobulin level was significantly lower in the treated group but at 12 weeks this difference was no longer present. Four of the treated mink had normal target organ histology when killed at 20 weeks. The untreated group all showed moderate to marked changes but this difference was not statistically significant. There was a marked increase in the reactive lymphocyte blastogenesis index during the first weeks of infection and the phytohaemagglutinin response was seen to fall progressively. The antiglobulin reaction usually became positive after infection but neither antinuclear nor antierythrocyte antibodies were found. Precipitating antibodies to several polynucleotides were frequently present and were unrelated to infection or to Poly IC treatment. (+info)
Coombs test - Wikipedia
A Coombs test (also known as antiglobulin test or AGT) is either of two clinical blood tests used in immunohematology and immunology. The two Coombs tests are the direct Coombs test (DCT, also known as direct antiglobulin test or DAT), and the indirect Coombs test (also known as indirect antiglobulin test or IAT) The direct Coombs test is used to test for autoimmune hemolytic anemia; i.e., a condition of a low count of red blood cells (a.k.a. RBCs) caused by immune system lysis or breaking of RBC membranes causing RBC destruction. In certain diseases or conditions, an individuals blood may contain IgG antibodies that can specifically bind to antigens on the RBC surface membrane, and their circulating RBCs can become coated with IgG alloantibodies and/or IgG autoantibodies. Complement proteins may subsequently bind to the bound antibodies and cause RBC destruction. The direct Coombs test is used to detect the antibodies or complement proteins that are bound to the surface of red ...
S there difference between indirect and direct coombs test - Things You Didnt Know
S there difference between indirect and direct coombs test - S there difference between indirect and direct Coombs test? Yes. The direct Coombs test is typically used to test for autoimmune hemolytic anemia, a disorder involving destruction of red blood cells. It determines whether or not antibodies are present on the surface of the patients rbcs. The indirect Coombs test is typically used to test for blood type compatibility prior to a transfusion, and detects the presence of antibodies in the serum of the patient.
DailyMed - METHYLDOPA- methyldopa tablet
It is important to recognize that a positive Coombs test, hemolytic anemia, and liver disorders may occur with methyldopa therapy.The rare occurrences of hemolytic anemia or liver disorders could lead to potentially fatal complications unless properly recognized and managed. Read this section carefully to understand these reactions. With prolonged methyldopa therapy, 10% to 20% of patients develop a positive direct Coombs test which usually occurs between 6 and 12 months of methyldopa therapy. Lowest incidence is at daily dosage of 1 g or less. This on rare occasions may be associated with hemolytic anemia, which could lead to potentially fatal complications. One cannot predict which patients with a positive direct Coombs test may develop hemolytic anemia.. Prior existence or development of a positive direct Coombs test is not in itself a contraindication to use of methyldopa. If a positive Coombs test develops during methyldopa therapy, the physician should determine whether hemolytic anemia ...

Antibody titer - Wikipedia
An antibody titer is a measurement of how much antibody an organism has produced that recognizes a particular epitope, expressed as the inverse of the greatest dilution (in a serial dilution) that still gives a positive result. ELISA is a common means of determining antibody titers. For example, the indirect Coombs test detects the presence of anti-Rh antibodies in a pregnant womans blood serum. A patient might be reported to have an indirect Coombs titer of 16. This means that the patients serum gives a positive indirect Coombs test at any dilution down to 1/16 (1 part serum to 15 parts diluent). At greater dilutions the indirect Coombs test is negative. If a few weeks later the same patient had an indirect Coombs titer of 32 (1/32 dilution which is 1 part serum to 31 parts diluent), this would mean that she was making more anti-Rh antibody, since it took a greater dilution to abolish the positive test. Many traditional serological tests such as hemagglutination or complement fixation ...
Questionable Diagnosis of Hemolytic Anemia? | The Journal of the American Osteopathic Association
The authors also stated that a Coombs test was not administered because the patient had already received corticosteroids.1 The Coombs test is an essential diagnostic test in the clinical approach to hemolytic anemia because of its substantial positive predictive value and its ability to differentiate warm from cold autoantibodies.3 This differentiation is important as the treatments associated with each condition vary. The administration of corticosteroids does not preclude obtaining a Coombs test in this case1 for two reasons. First and most importantly, several different mechanisms of corticosteroid action in hemolytic anemia have been described in the literature, but only decreased antibody production directly affects the Coombs test.3 However, several weeks of therapy are usually required before this effect is observed.3 Second, the patient in this case1 received only 40 mg/d of prednisone-below the current weight-dependent guidelines of 1 mg/kg prednisone (usually administered in dosages of ...

Diagnosis of Autoimmune Hemolytic Anemia (AIHA) | MedicalCRITERIA.com
Two criteria must be diagnose AIHA: serologic evidence of an autoantibody and clinical or laboratory evidence of hemolysis. Serologic evidence of an autoantibody is provided by positive autocontrol and direct antiglobulin test (DAT, direct Coombs´ test) results and subsequent identification of an autoantibody in the RBC eluate and possibly the serum. Serum reactivity with autologous RBCs generally indicates the presence of an autoantibody, but it does not exclude the presence of an autoantibody. ...
The DAT (Direct Coombs test) is positive if red cells have been coated, in vivo, with immunoglobulin, complement, or both. A positive result can occur in immune-mediated red cell destruction, autoimmune hemolytic anemia, a transfusion reaction or in patients receiving certain drugs.

Anemia Associated with Lead Poisoning - Clinical Advisor
If a hemolytic anemia is in the differential, haptoglobin, lactate dehydrogenase (LDH), and bilirubin can be useful. Haptoglobin scavenges free hemoglobin and is low in hemolytic anemia.. Hemolysis may also lead to elevated LDH and bilirubin. LDH is present in red cells, and hemolysis causes release into the plasma. Bilirubin is a breakdown product of hemoglobin and becomes elevated as hemoglobin is released. Indirect hyperbilirubinemia is typically seen in hemolysis.. Review of the peripheral smear is crucial. Patients with lead poisoning will often show basophilic stippling. Microcytosis and hypochromia may be present, and reticulocyte counts may be elevated.. The direct antiglobulin test (DAT, direct Coombs test) should be negative (see chapter on laboratory testing for lead).. ...
Coombs Test: Types, Principle, Procedure and Results - Learn Microbiology Online
Red blood cells contain various antigens in its surface. RBC containing antigen A, B, and AB in its surface are designated as blood group A, B and AB respectively. Blood group O do not contain both antigen A and antigen B in its surface. These blood group antigens are carbohydrate molecule. Our immune system usually makes IgM class of antibodies against carbohydrate antigen (as it gets no sufficient signals for class switching). These IgM antibodies (which are pentameric in nature) can bind specific antigens present in the surface of RBCs and can agglutinate RBC. So antibodies against ABO blood group antigens are called complete antibodies. RBC also contains another antigen in its surface, which is called Rh antigen. Rh antigens are protein in nature. When a person lacking Rh antigen (e.g. having negative blood group) is exposed to Rh antigen (during blood transfusion or mother during delivery of children having positive blood group), his/her immune system makes antibodies against Rh ...
Coombs Test Dalton GA | AOG Dalton
Rh is an antigen. The full name for this antigen is Rhesus factor.. If a pregnant woman with Rh-negative blood is pregnant with a baby (fetus) with Rh-positive blood, Rh sensitization may occur. The baby may have Rh-positive blood if the father has Rh-positive blood. Rh sensitization happens when the babys blood mixes with the mothers blood during pregnancy or delivery. This causes the mothers immune system to make antibodies against the babys red blood cells in future pregnancies. This antibody response is called Rh sensitization and, depending on when it happens, can destroy the red blood cells of the baby before or after it is born. If sensitization happens, a fetus or newborn can develop mild to severe problems (called Rh disease or erythroblastosis fetalis). In rare cases, if Rh disease is not treated, the fetus or newborn may die.. A woman with Rh-negative blood can get a shot of Rh immunoglobulin (such as RhoGAM) that almost always stops sensitization from occurring. Problems from Rh ...

Two weeks later Connie Mack inserted Coombs into the ninth inning of a 3-3 tie against Ed Walsh of the White Sox when Eddie Plank was removed for a pinch hitter. For the next three innings Jack held the Pale Hose hitless as the As finally pushed across a run in the eleventh to win 4-3. His rediscovery of his overhand curve apparently was the key. As former catcher Malachi Kittridge observed, Coombss devastating breaking pitch wasnt one of those outdrops, but a ball that comes up to the plate squarely in the center and falls from one to two feet without changing its lateral direction. His season revived, Coombs found himself starting two to three times a week on the way to his remarkable 31-9 season. On August 4 he again hooked up against Walsh in a sixteen-inning duel that ended in a scoreless tie because of darkness. Coombs considered this the best game he ever pitched.

The anti-globulin or Coombs test is widely used to detect the presence of antibody in the diagnosis of autoimmune hemolytic anemia. Antibody alone or in the presence of complement injures the cell membrane permitting leakage of RBC material, allowing recognition by the reticuloendothelial cells, thereby leading to phagocytosis and destruction of RBCs. Anti-globulin reagent (Coombs serum) is prepared by immunizing rabbits with canine IgG, IgM and C3 purified from normal serum. The resulting whole antiserum is heat treated to inactivate complement and is adsorbed with normal pooled canine erythrocytes to remove nonspecific agglutinins. ...

Erythropoietin mimics the acute phase response in critical illness | Critical Care | Full Text
In a prospective observational study, we examined the temporal relationships between serum erythropoietin (EPO) levels, haemoglobin concentration and the inflammatory response in critically ill patients with and without acute renal failure (ARF). Twnety-five critically ill patients, from general and cardiac intensive care units (ICUs) in a university hospital, were studied. Eight had ARF and 17 had normal or mildly impaired renal function. The comparator group included 82 nonhospitalized patients with normal renal function and varying haemoglobin concentrations. In the patients, levels of haemoglobin, serum EPO, C-reactive protein, IL-1β, IL-6, serum iron, ferritin, vitamin B12 and folate were measured, and Coombs test was performed from ICU admission until discharge or death.

Anti-D and anti-c are the two commonest antibodies that contribute to serious haemolytic disease of the foetus and neonate (HDFN). Current practice in the UK is to monitor these antibodies by CFA quantification, which is considered more reproducible and less subjective than manual titration by tube IAT (indirect antiglobulin test). CAT is widely used in transfusion laboratory practice and provides a more objective endpoint than tube technique. ...
Musings on transfusion medicine: 2014
Years ago when working in a combined centralized transfusion service/blood centre, one weekend when on shift by myself, I crossmatched a group AB patient for several RBC.

If there are fragments, it is consistent with a microangiopathic hemolytic anemia. Fragments are broken apart red blood cells; the red blood cells are broken apart in the intravascular system when there is damage and clot formation in blood vessels that the red blood cells get trapped in and ripped apart. There could also be other indicators of hemolysis including: elevated LDH, elevated indirect bilirubin, and decreased haptoglobin. It is not an immune related cause of hemolysis so the DAT (direct antiglobulin test) should be negative ...

On Friday night at Padonia Park Club in Timonium, MD, DJ Frank returned for the 2nd year in a row to DJ/MC an incredible event, the Kendall Burrows Foundations annual Footloose Gala. Kendall Burrows was diagnosed at age three and suffered from a rare autoimmune disease known as Evans syndrome, which is when the body makes antibodies that destroy red blood cells, platelets, and white blood cells. Patients with Evans contract thrombocytopenia and Coombs positive hemolytic anemia and have no other known underlying etiology. The specific cause for Evans syndrome is unknown and there have been no genetic links identified although her mother Deborah also has Evans. Throughout her lifetime, Kendall was in and out of remission with Evans. When in remission, she was a happy, normal little girl that enjoyed a plethora of activities, including contact sports and all forms of dance. When her blood levels were reduced to life-threatening numbers, she was unable to participate and was often ...
