« Go Back



I had an exposure and took PEP for 28 days which i started within 72 hours. I did the following tests which all came back non reactive:

1) At 105 days post exposure (76 days post pep) 3rd Generation HIV Elisa Antibody test which was non reactive.
2) At 119 days post exposure (90 days post pep) Determine HIV Antibody test which was still non reactive.
3) At 122 days post exposure-Hepatitis C rapid test which came back non reactive as well. Can i consider my results conclusive since the guidelines state that delayed seroconversion only occurred in people who acquired Hepatitis C together with the HIV virus. Please respond and this will be the last time am asking.


Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about the conclusiveness of your test results, given 76, 90, and 93 days Post-PEP.

While you received earlier testing, official HIV testing guidelines recommend re-testing at approximately 12 weeks for completely conclusive results (1). Since your 93 day Post-PEP results returned non-reactive, you can confidently consider your HIV status to be negative.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.

All the best,
