Table 3.
IgM positivity | No. of cases | % (no.) of samples positive by: |
||
---|---|---|---|---|
PRNT90 with IgG depletion | DENV NS1 assay | PRNT90 with IgG depletion and NS1 assay | ||
DENV = WNV | 23 | 74 (17) | 17 (4) | 4 (1) |
WNV > DENV | 20 | 70 (14) | 20 (4) | 10 (2) |
Total | 43 | 72 (31) | 19 (8) | 7 (3) |
This table presents the total numbers of cases that were either not interpretable by MAC ELISA alone or that were potentially false positive for WNV in this study. These cases were resolved by the PRNT90 with IgG depletion and/or the DENV NS1 ELISA.
