Results
Samples were obtained from 438 participants; in 72 samples blood was
insufficient for the Platelia ELISA. Specificity of the rapid test and
Platelia ELISA were similar (>93%) but sensitivity was low
(rapid test 61.3%; Platelia ELISA 83.4%). The Wantai ELISA showed
greater positivity (82.6%) than the rapid test (51.8%) and Platelia
ELISA (69.7%).
