Seroreactivity of H5N1 seroconversion panels in H5N1-SeroDetect ELISA soon after infection in H5N1 survivors. Sequential plasma samples obtained soon after acute infection up to 2 months from individuals who survived H5N1 (clade 2.3.4) infection in Vietnam were tested in the H5N1-SeroDetect. Reactivities of two representative sequential samples from males (aged 21 and 30 years) with HA2 (488–516) (A), PB1-F2 (2–75) (B), and M2e (2–24) (C) peptides. All plasma samples were tested at a 1:100 dilution. All data are represented as test specimen ODs on the y axis. The cutoff value for each peptide was determined as the mean absorbance + 5 standard deviations obtained with H5N1-seronegative samples (Fig. 2) and was <0.11 for each of the three peptides. The cutoff value for each peptide is shown as a dashed line in each graph.
