intra-assay coefficient of variation 变异内检测系数/ [医]检查中的变化系数
intraassay precision计算公式 "Intraassayprecision"是指在同一次实验或测量过程中，同一样本被多次测量时的精确度。通常，它用于评估测量方法的可重复性。计算"intraassayprecision"的一种常见方法是使用标准偏差（StandardDeviation）或变异系数（CoefficientofVariation）。标准偏差（SD）的计算公式如下：\[SD=\sqrt{\frac...
Inter- and Intra-Assay Coefficients of Variability In order to express the precision, or repeatability, of immunoassay test results, researchers in the social and behavioral sciences typically report two measures of the Coefficient of Variability (CV) in their publications: the Inter-Assay CV and th...

The protocol for 96-well plates typically resulted in high intra-assay CVs (>27%). Assessment of intra-assay variation is essential when DBS telomere length is measured by qPCR. 展开 关键词: coefficient of variation dried blood spot qPCR telomere length EPIDEMIOLOGY ...
The intensity of color was read using a programmable spectrophotometer (SpectraMax M2, Molecular Devices, Sunnyvale, CA). The concentra- tions of fragment Bb in AF samples were determined by interpolation from individual standard curves. The calculated inter- and intra-assay coefficients of variation ...

The sensitivity was 0.3 ng/mL; intra- and interassay coefficients of variation were 8.3% and 12.5%, respectively. The cortisol concentrations were determined by the RIA method according to Kokot and Stupnicki [44], using rabbit anticortisol antisera (R/75) and HPLC grade cortisol standard (...
Sample collection and assay procedures CSF Aβ38, Aβ40, and Aβ42 concentrations were measured using human Aβ38/Aβ40/Aβ42 multiplex assays (using 6E10 as detection antibody) following the manufacturer’s procedure (Meso Scale Discovery, Gaithersburg, MD). To avoid inter-plate variation, ...
However, the homocysteine values of any given individual varied up to 60% (rises up to 7 mumol/L and falls of 5 mumol/L) during folic acid supplementation despite the controlled circumstances of blood handling, and an assay coefficient of variation of 8%.Although group values of serum ...
