ABSTRACT
Significant advances were made in the diagnosis of filariasis in the 1990s with the emergence of three new alternative tools ultrasound and tests to detect circulating antigen using two monoclonal antibodies, Og4C3 and AD12-ICT-card. This study aimed to identify which of these methods is the most sensitive for diagnosis of infection. A total of 256 individuals, all male and carrying microfilariae (1-15,679 MF/mL), diagnosed by nocturnal venous blood samples, were tested by all three techniques. The tests for circulating filarial antigen concurred 100 percent and correctly identified 246/256 (96.69 percent) of the positive individuals, while ultrasound detected only 186/256 (73.44 percent). Of the circulating antigen tests, ICT-card was the most convenient method for identification of Wuchereria bancrofti carriers. It was easy to perform, practical and quick.
