Methodology
Recruited men who have sex with men from Sept 4 - Nov 5 2013 who had participated in prior research. Collected demographic information and asked participants to perform 2 different rapid tests for self-testing (1) oral fluid-based and (2) blood-based. Participants were asked to read instructions and they had an option of watching videos on how to perform the test. Participants then reported their results using an electronic survey. Participants were also asked to interpret the results of contrived panels for both self-test. Study staff observed each participant and completed a check list to document the procedures and verify participant-interpreted test results.

Summary of findings
Of 22 men who have sex with men, 17 reported being HIV-negative, 5 reported being HIV-positive. Most men read instructions before conducting the test (95%). However only 19% and 14% watched the instructional videos provided. One participant fainted before using the blood-based HIV self-test. Most were able to perform both type of self-tests. 76% correctly conducted and 95% correctly interpreted the blood-based self-test. 91% correctly conducted and 95% correctly interpreted the oral fluid-based self-test. 5 errrors were observed with the blood-based test and 3 errors were observed with the oral fluid-based test.
