  1. question

    Hi doctor, would like to ask, if i have taken pep, and do a rapid test on 84days post exposure (52days after complete pep med), would the result be conclusive?


    • drtan

      According to some guidelines it is conclusive however the majority of other guideline still recommend a retest at 6 months. For my opinion in this matter click HERE to read my article on when to test for HIV after PEP.
