Three new and commercially available tools for diagnosis of Wuchereria bancrofti infections based on detection of specific circulating antigens were evaluated and compared in the same group of individuals from a highly endemic village in southern Ghana. The tests were: (1) the ICT card test for serum specimens; (2) the TropBio ELISA test for serum specimens; and (3) the TropBio ELISA test for filter-paper specimens. A high degree of positive/negative response similarity was observed for the 3 tests, and the sensitivity for detecting microfilaraemic cases was 100% for all tests. The antigen levels measured in the TropBio serum test and the TropBio filter-paper test were statistically significantly correlated. Among antigen-positive endemic individuals the antigen levels in these 2 tests furthermore showed a positive association with the microfilarial intensity, but a statistical significant correlation was seen only for the filter-paper version of the test. The results are promising for the use of the 3 tests as diagnostic tools in bancroftian filariasis.
