Performance of two UCP-CF antibody assays. Comparison of the UCP-CF antibody assays with an in-house ELISA to detect anti-SEA antibodies using a set of sera from a previous WHO serum bank, comprised of 28 antibody negatives and 34 antibody positives. (Panel A) The ELISA and UCP-CF performed with SEA. (Panel B) The UCP-CF assays performed with SEA and SCAP. The high and low specificity cut-off thresholds for this experiment are determined according to the protocol described for the antigen assay. The dotted line indicates a threshold for the UCP-CF SEA antibody assay such that the UCP-CF test results match the SEA antibody ELISA. The indicated ELISA cut-off is defined as the average value of the negatives plus 3 s.d.
