Study participants were characterized as endemic normals (EN), considered to be healthy individuals, Wuchereria bancrofti-infected (Wb-inf.) or patients with lymphedema pathology (LE). EN participants were negative for both the Filariasis Test Strip (FTS) and TropBio Og4C3 Filariasis Antigen ELISA (TropBio), Wb-infected participants were positive for both the FTS and TropBio tests, and the LE group was defined by the presence of pathology which was classified according to the Dreyer staging protocol (Dreyer et al., 2002). Table 1 summarizes total sample size, age, gender, years living in the endemic area, as well as mean rounds of MDA received and median lymphedema stage. NA, not applicable.
