Inter- and Intra-Assay Coefficients of Variability Example 1. Calculating Inter-Assay CV: The Average Coefficient of Variation from Plate Control Means. In this example the same high and low cortisol controls are run in quadruplicate on ten different plates to ...

The inter- and intra-assay coefficients of variation were less than 10%. To standardize against the possible differences of AF osmolality, AF levels of sFas were normalized by AF creatinine concentrations. Amniotic fluid creatinine levels were measured using the alkaline picrate method (Sigma ...
The minimum detectable amounts of estradiol and FSH were 1.4 pg/ml and 0.46 mIU/ml, respectively. The intra- and inter-assay coefficients of variation were all <10% and <15%. Data analysis We conducted at least three replicate trials for each treatment. Data were analyzed by ANOVA,...
assay coefficients of variation were <5.0, <10.0, and <15.0 % for 6, 7, and 9 genera, respectively, out of the 22 selected human intestinal bacteria (>0.2 % of the total human gut microbiota), except forOdoribacter.Inter-assay coefficients of variation based on replicate analyses of a ...
The inter- and intra-assay coefficients of variation for NEFA, BHB, BUN, glucose, insulin, Hp, and tCa were the following: 3.1% and 3.8%, 5.2% and 4.5%, 6.5% and 2.3%, 2.7% and 4.5%, 2.6% and 5.5%, 14.1% and 3.7%, and 10.7% and 3.6%. Cytokine concentrations in serum at 0...
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 (...
The inter- and intra-assay coefficients of variation (CV) were < 10%. Diagnosis and definition Polycystic ovaries were defined as follows: the presence of 12 or more follicles in each ovary measuring 2–9 mm in diameter and/or increased ovarian volume (> 10 mL for one or both ovaries) ...
Analytes were measured in duplicate, samples with signal coefficients of variation greater than 25% were excluded and concentrations below the LLOD were considered undetectable (0 pg ml−1). Data were log2 transformed for analysis, and fold changes are presented on the log2 scale. Full ...
Evidence of incomplete combustion of gasoline was found in the ultrafine and accumulation size fractions, while possible diesel emissions were traced to ultrafine particles. Coefficients of divergence and coefficients of variation were investigated to determine the spatial and temporal variability of ...
