This assay was developed for the detection of IgG4 subclass antibody to enhance specificity without sacrifice of sensitivity. Antigens of Dirofilaria immitis are employed that serologically crossreact with all filarial species, including W. bancrofti, B. malayi and O. volvulus. Chronic elephantiasis may not result in a significant IgG4 antibody response and cannot be ruled out by this test.
