Develop a mobile reader application for use at the point-of care for the POC-CCA assay used for mapping and surveillance of Schistosoma mansoni. The reader apk will provide results consistent with the visual human reading of the test. Distinguishing intensity bands and reading 'Trace' results can be problematic and leads commonly to 'false positive' readings. The apk being developed will utilize a testing algorithm to better distinguish between true positive and false positive "Trace" test results.
