What is the window period for PEP?

Aug 27, 2009

I am taking prescribed Combivir and Kaletra twice a day for 28 days after a risk with a known HIV+ person. How long must I wait since the time of my exposure until I can have 99.9% confidence in my HIV test (provided it is negative)?? I'm so traumatized by this, but I have accepted both outcomes, so it's making the waiting a little easier.

Response from Dr. Frascino


The recommendation for post-PEP HIV screening is to get an HIV-antibody test at six weeks, three months and six months after the date of exposure.

Good luck.

Dr. Bob
