Conclusive result after PEP

May 2, 2012

Hello Doctors. A Abbott's test (chemiluminescence - antibody and antigens HIV1 HIV2 ) with result negative, 80 days after finish PEP can be considered conclusive or need be tested again? Thanks.

Response from Dr. Young


A negative HIV test more than 90 days after an exposure is generally considered definitive. There's no need to test after this point.

Anyone who has ongoing risks (that could be as simple as being sexually active), IMHO, should have an HIV test at least annually.
