TY - JOUR. T1 - Reference change values. AU - Fraser, Callum G.. PY - 2012/5. Y1 - 2012/5. N2 - Reference change values (RCV) provide objective tools for assessment of the significance of differences in serial results from an individual. The concept is simple and the calculation easy, since all laboratories know their analytical imprecision (CVA) and estimates of within-subject biological variation (CVI) are available for a large number of quantities. Generally, CVI are constant over time, geography, methodology and in health and chronic stable disease. The formula is RCV = 2(1/2) . Z . (CVA2 + CVI2)(1/2), where Z is the number of standard deviations appropriate to the probability. Correct interpretation of the semantics describing the clinical use of RCV is vital for selection of the Z-score. Many quantities of clinically importance exist for which good estimates of RCV are unavailable. Derivation of CVI may be difficult for such quantities: flair and imagination are required in selecting ...

Background and Objectives: Laboratory reference values are an important tool for clinical management of patients. Reference values being used in most laboratories in Iran have been provided from the established reference values from developed countries. However, several variables can affect on these laboratory parameters. Therefore, this study was carried out to establish the reference values of hematological parameters in the blood donors of central province of Iran as a general population. Methods: Blood samples of 1100 male blood donors were collected consecutively from Blood Transfusion Organization. Complete blood cell (CBC) count in 2012 and differential was performed using an automated hematology analyzer. Results: The median and 95% reference values (2.5th-97.5th) for Hb and platelet counts were 15.5 g/dl (14.1-17.7) and 209 ×109 cells/L (151-322) respectively. The median for total WBC count, neutrophil, lymphocyte, monocyte and eosinophil were 6.7 ×109 cells/L (4.3-11.2), %58 (%50-%70),
Age- and sex-specific reference intervals are an important prerequisite for interpreting thyroid hormone measurements in children. However, only few studies have reported age- and sex-specific pediatric reference values for TSHbasal (TSH), free T3 (fT3), and free T4 (fT4) so far. Reference intervals are known to be method- and population-dependent. The aim of our study was to establish reference intervals for serum TSH, fT3, and fT4 from birth to 18 years and to assess sex differences. 2,194 thyroid hormone tests obtained from a hospital-based pediatric population were included into our retrospective analysis. Individuals with diagnoses or medications likely to affect thyroid function were primarily excluded, as well as the diagnostic groups, if different from the purely healthy subgroup (n = 414). Age groups were ranging from 1 day to 1 month, 1 - 12 months, and 1 - 5, 6 - 10, 11 - 14, and 15 - 18 years, respectively. Levels of fT3, fT4 and TSH were measured on Advia® Centaur™ automated immunoassay

Thrombin-antithrombin III complex (TAT) concentration was measured in 27 control and 155 intensive care patients to (a) establish normal reference ranges, (b) measure thrombin generation in critically ill patients, and (c) determine the characteristics of the TAT assay for the diagnosis of disseminated intravascular coagulation (DIC) in children. The normal reference range was 1-4.3 micrograms/l (median 2.3 micrograms/l), and 89.7% of patients had raised TAT concentrations. Median TAT concentrations in the presence of DIC (27 micrograms/l) were significantly higher than in its absence (8 micrograms/l). Sensitivity, specificity, and positive and negative predictive values of the assay were 97.3%, 28.3%, 76.3%, and 81.3%, respectively, at a cut off of 4 micrograms/l. Excess thrombin production occurs in the majority of critically ill children. The TAT assay is potentially useful in the diagnosis of DIC in children.. ...

This study established height-specific BMI reference curves for Japanese children and adolescents aged from 5 to 17 years. Methods: The 2001 nationwide survey data were utilized for the study. First, the range of variation in BMI corresponding to height (mean ± 2SD) at each age was compared with the range of variation in BMI corresponding to age (from minimum to maximum) at every cm height. Second, various age groups were combined, and percentile values of BMI (3rd, 5th, 15th, 50th, 85th, 95th, and 97th) were calculated for every cm height, regardless of age, and height-specific BMI reference values (males ...
AIM: To develop age-, sex-, and ethnic-appropriate normative reference ranges for standard echocardiographic measurements of the left heart by combining echocardiographic measurements obtained from adult volunteers without clinical cardiovascular disease or significant cardiovascular risk factors, from multiple studies around the world. METHODS AND RESULTS: The Echocardiographic Normal Ranges Meta-Analysis of the Left heart (EchoNoRMAL) collaboration was established and population-based data sets of echocardiographic measurements combined to perform an individual person data meta-analysis. Data from 43 studies were received, representing 51 222 subjects, of which 22 404 adults aged 18-80 years were without clinical cardiovascular or renal disease, hypertension or diabetes. Quantile regression or an appropriate parametric regression method will be used to derive reference values at the 5th and 95th centile of each measurement against age. CONCLUSION: This unique data set represents a large, ...

The data stored by IMD 14 may include continuous monitoring of various parameters, for example recording intracardiac EGM data at sampling rates as fast as 256 Hz or faster. In certain embodiments of the invention, an IHM may alternately store summary forms of data that may allow storage of data representing longer periods of time. In one embodiment, hemodynamic pressure parameters may be summarized by storing a number of representative values that describe the hemodynamic parameter over a given storage interval. The mean, median, an upper percentile, and a lower percentile are examples of representative values that my be stored by an IHM to summarise data over an interval of time (e.g., the storage interval). In one embodiment of the invention a storage interval may contain six minutes of data in a data buffer, which may be summarized by storing a median value, a 94th percentile value (i.e., the upper percentile), and a 6th percentile value (i.e., the lower percentile) for each hemodynamic ...
A systematic approach was used to set HP2020 targets for all dietary intake objectives. First, a challenging but achievable HP2020 target was considered, at a minimum, to be a shift in the baseline mean intake for the total population: 1) to the 75th percentile value of the baseline usual intake distribution for objectives aiming to increase consumption and 2) to the 25th percentile value for objectives aiming to decrease consumption. The need for any adjustments to these initial targets was then assessed by examining baseline estimates in relation to recommendations, target applicability to subpopulations, the ability to detect change over time, past trends and whether the same trend would be anticipated this decade, and additional considerations for each objective. Based on this approach, the HP2020 target selected for mean fruit consumption was 0.9 cup equivalents (c) per 1,000 calories (about the 75th percentile of the baseline usual intake distribution). Considerations include: Most ...
2. 2 Sample Percentile (or Quartile) Speed Values (mph) Source: John McFadden/Dave Petrucci. Any data value that falls below the lower fence or above the upper fence may be considered an outlier. Another approach used to identify lower and upper fences is: Where: Q1 = 1st quartile (25th percentile value) Q3 = 3rd quartile (75th percentile value) IQR = Interquartile range = Q3 − Q1 The use of the percentiles to establish fences is sometimes preferred over the mean and standard-deviation approach because of the fact that the mean and standard deviation are not resistant to the outliers we are trying to identify. Graphs and tables also provide information on how the data are distributed. Content created by John McFadden/Dave Petrucci. Content created by John McFadden/Dave Petrucci.

Reference curves for stature and weight in British children have been available for the past 30 years, and have recently been updated. However weight by itself is a poor indicator of fatness or obesity, and there has never been a corresponding set of reference curves to assess weight for height. Body mass index (BMI) or weight/height has been popular for assessing obesity in adults for many years, but its use in children has developed only recently. Here centile curves for BMI in British children are presented, from birth to 23 years, based on the same large representative sample as used to update the stature and weight references. The charts were derived using Coles LMS method, which adjusts the BMI distribution for skewness and allows BMI in individual subjects to be expressed as an exact centile or SD score. Use of the charts in clinical practice is aided by the provision of nine centiles, where the two extremes identify the fattest and thinnest four per 1000 of the population.. ...
You know the drill when it comes to hormonal blood work; its a lot of poking and prodding on multiple days of your menstrual cycle. In my experience, my patients have had all the right testing done (mostly), but no one has taken the time to sit down with them and explain what the results truly mean.. The biggest pitfall of serum (blood) hormone testing is that the reference ranges are MASSIVE. Which means it is highly unlikely that your results will be deemed abnormal even though you know something is wrong. So thats what this blog is for; Im going to break it all down for you and discuss what the results mean and the REAL range youre looking for. Note: the following reference ranges are for women and are Canadian units. 1) Estradiol ...

TY - JOUR. T1 - Reference values for normal regional lumbar sagittal mobility. AU - Burton, A. Kim. AU - Tillotson, K. Malcolm. PY - 1988/5/1. Y1 - 1988/5/1. N2 - From a sample of 958 individuals, a group with no anamnestic recall of notable low back trouble (n=510) was selected to provide reference values for lumbar sagittal mobility. The measurement technique employed a flexicurve to give angular measures for maximal sagittal mobility in upper (T12-L4) and lower (L4-S2) regions. The results are presented in the form of reference ranges and modal values, stratified by age and sex. A wide variation in the normal range of mobility at all ages is confirmed. Males had higher values for flexion, whilst females showed higher values for extension and for mobility in the lower region. Sagittal mobility declined with age at different rates in males and females for both flexion/extension and upper/lower measures. Generally speaking, mobility was reduced by some 50% in old age compared with childhood, ...

Abstract: In this study, we calculate confidence intervals for the mean of a normal data and a contaminated normal data. Some robust estimators against outliers are also considered to construct confidence intervals that are more resistant to outliers than the Student t confidence interval. The confidence intervals of these estimators are computed and compared with each other for normal and contaminated normal data to determine which is better. The performance of these confidence intervals is evaluated and compared by calculating the estimated coverage probability, the average width and the standard error by using simulation. Sps t followed by MAD t are recommended at any rate of contamination, while Student t is not preferred at all for contaminated data and the sample mean and the sample standard deviation are not good choices for constructing confidence interval, but highly recommended for normal data without outliers as expected ...

Aim: Empirical studies in medicine - and most other fields of study - yield results that are uncertain to a certain degree. Medical research on interventions has made tremendous leaps forward by quantifying and reporting this uncertainty using p-values and confidence intervals. In contrast to this, most diagnostic studies that determine optimal cutpoints or reference values for diagnostic measures ignore that their outcomes, i.e. the specific cutpoints or normal ranges they recommend, are subject to chance variability. Methods: In this paper we use a simple simulation approach to quantify the variability of optimal cutpoints for two published studies. The first determined an optimal cutpoint for Becks Depression Inventory (BDI) in adults. The second determined reference values for Quantitative Sensory Testing (QST) in children. Results: We find that frequently employed cutpoints to interpret BDI scores and QST results are highly variable. For the BDI we find that replication of this study may identify

Adult BP thresholds were applied to adolescents, because the 90th percentile value for 13-year-old boys and girls of average height was approximately 120/80 mm Hg and because this aligns with the updated guidelines for adult hypertension (3).. In the hypertension clinic, the patient denied any symptoms and had no other complaints. However, her mother volunteered that the girl snored and that polysomnography had been ordered by the pediatrician. Birth history was normal, and the only surgical procedure was a tonsillectomy 9 years previously. Family history was remarkable for hypertension and type 2 diabetes. The girl is a junior in high school and does not participate in any regular physical activity outside of gym class 2 d/wk. Physical examination is notable for weight of 83.1 kg (96th percentile) and body mass index of 31.1 kg/m2 (96th percentile), and it is otherwise normal..

Reference data has an importance that approaches metadata in terms of the significance of individual data values. Codes have definitions, not just corresponding descriptions. These definitions may not be formally stated, but they need to be understood to use the reference data tables. For instance, reference data is used to control business rules: if a business rule includes an actual data value, this will nearly always be reference data (i.e., a code). The semantics of the code value control the logic of the business rule. Codes are also important in reporting hierarchies, where users must understand what is meant by each of the categories appearing in a report.. Reference data, therefore, acts like metadata in certain respects, but it is not treated like metadata. IT professionals seem to view defining a database as an IT task, but populating it with data as the job of the business users. From this viewpoint, reference data values become the responsibility of the users. In reality, however, ...

Background: The objective of this study was to establish pediatric reference values and cut-offs for 8 plasma cytokines and chemokines in the CALIPER cohort to support their interpretation.. Methods:Healthy children and adolescents (n=311), aged 1-19 were recruited as part of CALIPER with informed consent. Analytes were measured in EDTA plasma using multiplex immunoassays (Panel 1: CD163, CXCL-9/MIG, IFN-& gamma;, TNF-α; Panel 2: IL-1β, IL-6, IL-10, IL-18, ProteinSimple® Ella™, Bio-Techne). Age and sex partitions were statistically evaluated using the Harris and Boyd method. After outlier removal, reference intervals were calculated using the non-parametric rank (n,120) and robust (n≤120) method, following CSLI C28-A3 guidelines. Additionally, 75th and 95th percentile cut-offs were determined.. Results: Three types of reference value distributions were observed: (a) consistent concentrations throughout age and sex: IL-6, and IFN-γ (b) gradual concentration decrease with age: CD163, ...
Toxicological Reference Values (TRVs) are developed to protect humans exposed at chemical substances via the environment either by oral or inhalation routes. These values are derived by different international agencies or organisms and used in risk assessment. It is important for risk assessors and managers who will analyze and use the conclusions of the risk assessment to understand the robustness and the degree of uncertainties of the TRV. The level of confidence in a TRV depends of several parameters used at each step of the construction of a TRV (selection of the critical effect, the dose and endpoint used for value derivation and uncertainty factors). Some organisms, such as US EPA or RIVM, attribute a confidence index to the value they have developed while others do not. In order to homogeneously inform risk assessors on the quality of values developed a confidence index could be proposed. This index may also help assessors to chose a TRV, if several values are available. To develop this index,

With aging, the incidence of falls and fractures increases. There has during the last decades been secular changes in demographics so that the proportion of elderly increases in society. Hence, there is an increasing need for clinicians to be able to make a solid appraisal of the elderly patients functional capacity, as to identify individuals with an increased risk to fall. If high risk individuals could be targeted fall preventive strategies might be implemented in specific risk cohorts. This would require reference values for muscle strength tests and functional tests, in order to defined high risk individuals performing inferior. From the MrOS Sweden cohort, 999 subjects aged 70-80 years were evaluated. Muscle strength and functional performance was tested by timed-stands test, 6-m and 20-cm narrow walk tests and Jamar handgrip strength test. Normative data is presented. With increasing age, there was a 10-18% successively decline in performance throughout the entire age span. This study ...

Quantitative T1-mapping is rapidly becoming a clinical tool in cardiovascular magnetic resonance (CMR) to objectively distinguish normal from diseased myocardium. The usefulness of any quantitative technique to identify disease lies in its ability to detect significant differences from an established range of normal values. We aimed to assess the variability of myocardial T1 relaxation times in the normal human population estimated with recently proposed Shortened Modified Look-Locker Inversion recovery (ShMOLLI) T1 mapping technique. A large cohort of healthy volunteers (n = 342, 50% females, age 11-69 years) from 3 clinical centres across two countries underwent CMR at 1.5T. Each examination provided a single average myocardial ShMOLLI T1 estimate using manually drawn myocardial contours on typically 3 short axis slices (average 3.4 ± 1.4), taking care not to include any blood pool in the myocardial contours. We established the normal reference range of myocardial and blood T1 values, and assessed

In this paper a new approach for calculating pelvis angles based on the rotations between the pelvis and an instantaneous progression reference frame was introduced. At every time-point, the tangent to the trajectory of the midpoint of the pelvis projected into the horizontal plane of the laboratory reference frame was used to define the anterior-posterior axis of the instantaneous progression reference frame. This new approach combined with the rotation-obliquity-tilt rotation sequence was compared to the conventional approach using the rotation-obliquity-tilt and tilt-obliquity-rotation sequences. Four different movement tasks performed by eight healthy ...
Result: The result column shows counts that fall within the normal range.. Flag: Counts that are above or below the reference range are recorded in the flag column, and marked with an L for low or H for high.. Reference interval (or reference range): The reference interval shows the normal range for each measurement for the lab performing the test. Different labs may use different reference intervals.. White blood cells: White blood cells help protect individuals from infections. The above CBC report shows that the patients total white cell count is 7.2, which is within the normal range of 4.0-10.5.. Red blood cells: Red blood cells carry oxygen from the lungs to the rest of the body. The above CBC report indicates that the patient has a red cell count of 3.5. This count is lower than the normal range of 4.7-6.1, and is therefore recorded in the flag column and marked with an L for low.. Hemoglobin (Hb or Hgb): Hemoglobin is a protein in the red cell that carries oxygen. The above CBC ...
In the context of large-scale human system immunology studies, controlling for technical and biological variability is crucial to ensure that experimental data support research conclusions. In this study, we report on a universal workflow to evaluate both technical and biological variation in multiparameter flow cytometry, applied to the development of a 10-color panel to identify all major cell populations and T cell subsets in cryopreserved PBMC. Replicate runs from a control donation and comparison of different gating strategies assessed the technical variability associated with each cell population and permitted the calculation of a quality control score. Applying our panel to a large collection of PBMC samples, we found that most cell populations showed low intraindividual variability over time. In contrast, certain subpopulations such as CD56 T cells and Temra CD4 T cells were associated with high interindividual variability. Age but not gender had a significant effect on the frequency of ...

Our finding that ACS derived PAPP-A in circulation is not in complex with proMBP may have important clinical implications. In non-ACS individuals, variable levels of PAPP-A can be measured (22,26,44). The source of this immunoreactivity is not known, but may originate from seminal fluid, follicle fluid, corpus luteum, testes and other organs/tissues where PAPP-A expression has been reported (45). The PAPP-A concentrations determined for 80 non-ACS male subjects aged between 50 and 69 years varied from 1.51 to 7.59 mlU/L with a 97.5% upper reference limit of 5.68 mlU/L (22). The extent of increase in PAPP-A concentrations during ACS is widely variable but usually below 30 rnlU/L (22,23). Using the upper reference limit as the decision limit means that a significant proportion of patients with ACS can be missed. We have previously reported (22) that the PAPP-A values in five out of fourteen MI patients were below the upper reference limit despite showing clear dynamic changes over time. Ideally, a ...

Reference data are data that define the set of permissible values to be used by other data fields. Reference data gain in value when they are widely re-used and widely referenced. Typically, they do not change overly much in terms of definition, apart from occasional revisions. Reference data are often defined by standards organizations, such as country codes as defined in ISO 3166-1. Examples of reference data include: Units of measurement Country codes Corporate codes Fixed conversion rates e.g., weight, temperature, and length Calendar structure and constraints Reference data should be distinguished from master data, which represent key business entities such as customers and materials in all their necessary detail (e.g., for customers: number, name, address, and date of account creation). In contrast, reference data usually consist only of a list of permissible values and attached textual descriptions. A further difference between reference data and master data is that a change to the ...
If you have an underactive thyroidyour thyroid has been surgically removedor you have had radioactive iodine to treat an overactive thyroid, you may struggle with an inability to lose weight. In this situation, its helpful to understand the factors contributing to difficult weight loss and how you can address them so that you can lose weight with hypothyroidism. At that point, you are considered euthyroid, which means that your thyroid function is normal.. Some studies show, however, that TSH levels in weiyht upper end of the reference range are linked to increased weight, higher body mass index BMIand higher rates Can loss weight eutroxsig obesity. To that end, Caan physicians aim to keep the TSH level at the mid-point of the reference range, or even lower, in some eutroxxig. Conventional therapy for hypothyroidism is levothyroxinea synthetic form of the T4 hormone. Some studies, however, have shown that nutritional deficiencies, genetic defects, and Can i loss weight on eutroxsig factors ...
Because cardiovascular disease is the most common cause of death worldwide, more than half of the population can expect to develop cardiovascular disease during their lifetime.21 Thus, identifying QTL for cardiovascular disease-relevant phenotypes in healthy nonobese persons, and subsequently demonstrating variations in the corresponding candidate genes, is important to cardiovascular disease genetics. We believe that our study exemplifies the utility of this combined linkage and association approach. MZ and DZ twins permit quantification of genetic and environmental variance. As reported earlier,22 the body size parameters and serum lipid concentrations were all influenced by genetic variance. DZ twins, who are perfectly matched for age and who are generally exposed to very similar environmental conditions, are ideal subjects for efficient sib-pair analyses. Thus, far fewer subjects are needed to gain insight into QTL.. We showed that the PPARγ gene locus is a QTL for BMI, LDL, and HDL ...
Importantly, because many different definitions of cancer therapeutics-related cardiac dysfunction have been used historically, the committee specifically defined cardiotoxicity or cancer therapeutics-related cardiac dysfunction as a decrease in LVEF ,10 percentage points to a value ,53%, which is the normal reference value for two-dimensional echocardiogram. This expert consensus also acknowledged the use of global longitudinal strain as a potential marker for early detection of cardiotoxicity during cancer therapy.. A reduction of ,15% in global longitudinal strain from baseline immediately after or during anthracycline therapy may be predictive of cardiotoxicity; a reduction ,8% may not be clinically significant. The use of cardiac imaging was left to clinician discretion, but echocardiogram was recommended as the preferred imaging modality when performed. The panel also suggested the use of serum biomarker evaluation, including troponin and BNP, but did not mandate testing due to a lack of ...
The signal corresponds to the conductivity measurement of a water solution during the time, the conductivity value in the water solution is controlled by a slow feed-back system, the reference value is change lets suppose an increase in one unit, and some actuators increase the solution conductivity until the new reference value is achieved. So I guess that the function could be described as a step function with a high amortiguation ...

What are Nutrient Reference Values? In the 1991 Recommended Dietary Intakes (RDI) for use in Australia ( NHMRC 1991, Truswell et al 1990) an RDI value, sometimes presented as a range, was developed for each nutrient. The RDI was defined as: the levels

Objective data from the clinical laboratory are critical to the majority of medical decisions, including initial diagnosis and monitoring of treatment outcome. Laboratory errors, including inaccurate RIs, can lead to inappropriate diagnosis, unnecessary test repetition, and inappropriate follow-up investigations (7). Excessively wide RIs may mask subclinical disorders, and the use of incorrect RIs may confuse the clinical picture. Therefore, relevant RIs are essential for correct test result interpretation and reducing the risk of false negatives and false positives. Failure to provide proper RIs in the pediatric population carries obvious consequences for immunochemical analytes such as TSH (8) and ferritin (9).. The current investigation established RIs in a large, multiethnic pediatric cohort. However, the study was not without its limitations. As it was a cross-sectional investigation, the long-term health of the participating children was not verified. Additionally, the RIs provided are ...
The highest (spring) tidal ranges are generated when the sun, moon and earth are in line. Water flows in greater volumes when attracted by this combined gravitational pull. The lowest (neap) tidal ranges are generated when the sun, moon and earth describe a right angle. The split gravitational pull causes water to flow in lesser volumes.. Tidal stream resources are generally largest in areas where a good tidal range exists, and where the speed of the currents are amplified by the funnelling effect of the local coastline and seabed, for example, in narrow straits and inlets, around headlands, and in channels between islands ...

The Centers for Disease Control and Prevention (CDC) created the growth charts that are most commonly used in the United States. They were last updated in 2000. After collecting growth measurements from thousands of U.S. children over a period of time, the CDC was able to show the range of these measurements on one chart, using percentile curves.. Being in a high or a low percentile does not necessarily mean that a child is healthier or has a growth or weight problem. Lets say that 4-year-old boy, who is in the 10th percentile for weight, is also in the 10th percentile for height. So 10% of kids are shorter and weigh less than he does, and most kids - 90% - are taller and weigh more. That just means that hes smaller than average, which usually doesnt mean there is a problem. If his parents and siblings are also smaller than average, and there are other signs that hes healthy and developing well, doctors would likely conclude that theres no cause for concern.. ...

Reference Materials (RMs) are also available from Fapas for some analyte/matrix combinations. RMs have a much higher degree of characterisation than PT or QC materials with a defined chain of traceability. RMs undergo formal stability testing for both short-term and long-term applications. RMs have an associated datasheet which lists the reference values and their expanded uncertainty U. The value of U is not a performance limit but is the uncertainty relating to the reference value. RMs therefore have a greater degree of trust in their values and can be used for method calibration purposes. Fapas RMs are generated according to the principles of ISO Guide 34. ...
