Is the rna hiv test accurate to check if you were recently exposed? i read you can take it around 9-11 days at the earliest after exposure to get accurate results?

HIV RNA testing can be used following exposure, but should be limited to truly high risk exposures, like unprotected sex with a known infected partner. It's not a very good test if risk is lower. About 80-90% of new infections produce positive RNA tests after 9-12 days, but it takes 2-3 weeks for maximum test performance. Even then, a few infections may be missed; RNA should never be the only test
