Correlations between quantitative values for quantitative polymerase chain reaction assays and ReLASV immunoassay. Cycle threshold (Ct) values, which are inversely related to viral genome equivalents, obtained by Nikisins or Trombley qPCR were compared (Panel A). Densitometry scan ratios between the test and control bands of ReLASV RDT and the amount of LASV antigen (µg/ml) detected by ReLASV (Panel B). Nikisins qPCR values were compared to the quantitative vales of the ReLASV ELISA (Panel C) or RDT (Panel C). Only concordant results were compared. R-squares (R2) values for fit to the linear regression line are indicated.
