HIV tests after PEP
Mar 23, 2014

Just finished PEP and going in for my first HIV test (6 weeks after the exposure). I asked my doctor which type of test would be administered and he said an HIV Ab test would be given at 1 month, 3 months and again at 6 months to rule out infection. Question: are there any other types of test that could rule out infection sooner?

Response from Dr. Young

Hello and thank you for posting,

While fourth-generation HIV tests [test include both antibody and forest testing] allow for earlier detection of HIV, their use in ruling out HIV infection is somewhat less well researched.

As a result, guidelines for HIV testing after exposure generally still refer to the use of HIV antibody tests. Most recommendations only ask for testing at one and three months after exposure.
