Dried blood spots (DBS) were collected from 805 children attending 42 elementary schools in the regions of Mopti, Sikasso, Koulikoro, and the regional capital of Bamako in Mali as part of an evaluation of a school health intervention. Eluted immunoglobulin (Ig) G from the DBS was assessed by a multiplex bead assay (MBA) for two filariasis antigens, , Wb123, and , Bm14, to determine the effectiveness of mass drug administration (MDA) programs to eliminate lymphatic filariasis (LF). The prevalence of positive IgG responses in the children to each antigen was less than 1%, indicating effectiveness of the MDA against LF. The MBA is an excellent serological platform that provides cost-effective opportunities to evaluate public health activities beyond the survey targets.
