Comparison of Filariasis Binax Test and Alere Strip Test
Cross-sectional Community Surveillance Using Filarial Antigen and Microfilaria Tests in Post Mass Drug Administered Areas in Sri Lanka
Study Sites: Galle and Matara, Sri Lanka

Results from this study agree with similar studies from other sites that find the Alere test strips are more sensitive than the Binax Now test. Preliminary studies showed that there were many false positive results by test strip when blood was collected into EDTA tubes and tested the next day. The final results were published in Parasites & Vectors.

Research for Elimination of Lymphatic Filariasis
Study Sites: Galle, Sri Lanka

The DOLF project is now conducting further work on post-MDA surveillance for lymphatic filariasis with the Anti-Filariasis Campaign (AFC) using a variety of tools as described in Rao et al, 2014. This research will help improve end-game surveillance strategies in low prevalence settings where countries are nearing their elimination targets.

Washington University researchers also worked together with AFC and Sri Lankan scientists to develop a pilot project on integrated school-based surveillance for LF and soil transmitted helminth infections (Gunawardena et al, 2014.)
