Analytic performance of plasma blood screening and diagnostic assays.
Probit curves comparing analytical sensitivity of assays evaluated in this study by replicate testing of Polynesia isolate blinded panels, grouped by assay category or laboratories. The fitted probit regression model curve (solid lines) and standard errors were used to estimate LOD50 and LOD95 and confidence intervals presented in Table 2.
