Methodology
Modeled substitution of a single annual 4th generation enzyme immunoassay test with two oral fluid-based HIVST kits per year. Calcuated the proportion of infections that would be undiagnosed if substitution took place and the additional HIVST frequency needed to counter reduced sensitivity of HIVST compared to 4th generation enzyme immunoassay.

Summary of findings
If men who have sex with men, at high risk, used oral fluid-based HIVST instead of enzyme immunoassay, 6.5% of infections would go undiagnosed. If two HIVST kits were used in a year, the proportion undiagnosed decreases to 0.44%. If HIVST led to more frequent testing (2 to 2.8 tests per year) then all infections would be detected. If increase in testing was > 40% ( 2 to 4 self-tests a year) or men who never tested before self-tested, then additional infections would be detected.
