UNAIDS HIV prevalence (2017)

Methodology
Assessed test performance of an oral fluid-based HIVST compared to the National HIV rapid test algorithm and with automated HIV ELISA. The samples were obtained from the clients that were identified during the routine outreach services conducted by Society for Family Health sites or partners where HIV testing service is provided. Client giving verbal informed consent were tested with HIVST, national algorithm, and the fourth generation HIV test.

Summary of findings
457 individuals were tested, 8.8% (40/457) were identified as HIV-positive by the 4th generation laboratory test. The national algorithm identified 8.3% (38/457) individuals as HIV-positive. The oral fluid-test identified 8.1% (37/457) individuals as HIV positive (self-tester interpretation and trained tester interpretation). Using the 4th generation laboratory test as a gold standard, the national algorithm had a sensitivity of 95% and specificity of 100.0%. The oral fluid-based test had a sensitivity of 92.5% and a specificity of 100.0%.
