The inter-assay CV is an expression of plate-to-plate consistency that is calculated from the mean values for the high and low controls on each plate, as illustrated

Inter-assay CV is a measure of the variance between runs of sample replicates on different plates that can be used to assess plate-to-plate consistency. Percent Error or Coefficient of Variation (CV) CV is used to analyze series of values and is a measurement of precision. The smaller the variation between a data set the greater the precision Usually used in the laboratory to determine if the CV is within a certain standard deviation (SD) The inter-assay CV is an expression of plate-to-plate consistency that is calculated from the mean values for the high and low controls on each plate, as illustrated in Example 1 below (taken from internal Salimetrics data). Most studies measure each sample in duplicate for each analyte. The coefficient of variation (CV) for a sample is the standard deviation of the observations divided by the mean: Algebraically speaking - Coefficient of variation of the observations (CV) = In many laboratories, the variability of the ELISA and other methods of chemical assay that produce continuous-type values is summarized not by the standard deviation (SD) but by the CV, which is defined as the SD divided by the mean, with the result often reported as a percentage. The m:n:θ b procedure is often used for validating an assay for precision, where m levels of an analyte are measured with n replicates at each level, and if all m estimates of coefficient of variation (CV) are less than θ b, then the assay is declared validated for precision.

It is also commonly used in fields such as engineering or physics when doing quality assurance studies and ANOVA gauge R&R. [citation needed] In addition, CV is utilized by economists and investors in economic models Intra-assay CV is a measure of the variance between data points within an assay, meaning sample replicates ran within the same plate.

For qPCR assays, precision can be assessed using the coefficient of variation (CV) of the measured concentrations of standards (Kubista, 2014; Taylor, 1987). The concentration of target DNA at an assay's LOQ may be greater than or equal to the concentration identified as the LOD but cannot be less than the LOD (Armbruster & Pry, 2008 ; Kralik & Ricchi, 2017 ).

This is a simple assay useful for obtaining quantitative information about the relative density of cells adhering to multi-well cluster dishes. The dye in this assay, crystal violet, stains DNA. Upon solubilization, the amount of dye taken up by the monolayer can be quantitated in a spectrophotometer or plate reader.
