Production of a New Dual Antigen Test Strip as a Tool to Support Epidemiologic Assessments of Onchocerciasis

How does the performance of the new Ov16/Ov3261 test strip compare to that of the SD Ov16 RDT and the SD Ov16 ELISA?

Diseases: Onchocerciasis

Evaluation of rapid diagnostic test prototypes detecting Wb123 antibodies in populations with Loa loa

This is a cross-reactivity evaluation of rapid tests detecting Wb123 antibodies. The test should perform similarly in sub-populations of individuals who are positive and negative for other filarial diseases, most importantly Loa loa. This field evaluation will determine the specificity of the tests in two separate populations, those positive and negative for Loa loa, and will be used to inform the product design and the product insert. This evaluation will recruit adults and children from regions that are known to have Loa loa in Cameroon.

 The study’s principal objective is to determine test specificity in individuals who are positive and negative for the filarial worm Loa loa. Secondary objectives are to determine the test specificity in individuals who are positive and negative for Mansonella perstans, and identify failure modes and failure rates of the rapid tests under surveillance conditions.

Feasibility, acceptability and cost implications of utilizing the SD BIOLINE Onchocerciasis IgG4 rapid test for onchocerciasis surveillance activities in Senegal

The demonstration study of the SD BIOLINE Onchocerciasis IgG4 rapid test aims to provide operational research data on the use and implementation of the test. The performance of the SD BIOLINE Onchocerciasis IgG4 rapid test has been verified in both reference laboratories as well as in controlled field settings. PATH and partners will explore the feasibility of incorporating the test into multiple sites in sub-Saharan Africa, with Senegal as a pilot country.

 We aim to demonstrate the acceptability and feasibility of the SD BIOLINE Onchocerciasis IgG4 test in the Senegal Onchocerciasis Control Programme surveillance activities relative to the diagnostic and collection tools currently used.
