Which pre-test counseling option would you prefer?

Summary• MSM prefer less invasive specimen collection methods
• MSM trust lab based testing more than rapid HIV testing
• RNA testing was the most preferred single test
• MSM would like a provider to obtain consent for HIV testing
• MSM want pre-test counseling available with HIV testing
![Page 17: RNA Testing VS. Rapid Testing](https://reader034.vdocuments.mx/reader034/viewer/2022042613/54666dd9af795969458b4e9f/html5/thumbnails/17.jpg)
Limitations
• Testing information provided throughout testing session
varied by location/counselor
• Survey conducted after testing
• Not all study participants surveyed (HIV+, time restrictions)
• Representativeness: Population already seeking testing
• 4th generation test not FDA approved
![Page 18: RNA Testing VS. Rapid Testing](https://reader034.vdocuments.mx/reader034/viewer/2022042613/54666dd9af795969458b4e9f/html5/thumbnails/18.jpg)
Discussion
• Important to provide the most preferred types of testing
• Consider integrating RNA testing into rapid testing programs
• Once FDA approved, 4th generation rapid testing may
become a more preferable testing option
• Caution in separating both consent and counseling from HIV
testing
