“…The consistency of the PRRSV oral fluid ELISA was quantified by estimating reliability coefficients (ρ) for assay repeatability (within laboratory) and assay reproducibility (between laboratories) using the results from oral fluid samples of known (n = 39) and unknown (n = 224) PRRSV antibody status, respectively. 2,10 For calculation of repeatability reliability coefficients, the model and associated parameters were based on n samples with d repeated measurements of a continuous variable x and denoted by x ij , the jth measurement made on the ith subject (for i = 1, . .…”

“…That is, given the same assay, reliability coefficient estimates will be affected as the concentration and/or prevalence of the analyte in the population of samples tested varies. 2 Repeatability reliability coefficients were calculated using 13 samples tested on each ELISA plate in every laboratory (Table 3). Coefficients ranged from 0.724 to 0.997 (phase 1) and from 0.953 to 0.998 (phase 2).…”
