The encounter you described was very low risk for HIV or other STIs.  Most women do not have HIV and, on average HIV is acquired less than once in 2000 exposures to infected untreated persons.  Your use of PEP, while probably not necessary, lowered any risk still further.  Your test results prove that you were not infected and when you get your PCR results which I’m sure will also be negative, there will be no way that you were infected from the encounter you described.  Your Crohn’s disease therapy does not change this fact.

I hope that the information I’ve provided is helpful.  There is no need for further testing.  It’s time to move forward without concern.  EWH

So what you are saying is that while the CDC says 6 weeks after PEP 4th gen negative is confirmatory, in my situation with my exposure , with the completed PEP, I can move on with the negative test at 4 weeks. 

Does this mean if PEP had failed it would have been seen by this time and the test would have picked it up… IF I was even really exposed? And the rna test would pick it up even sooner after PEP? I only ask this because there is a lot of info out there about PEP delaying window times, sero conversion , etc etc. much more than any non-expert could even begin to understand. And don’t get me started with chatGPT…

We spend much of our time on this forum, trying to correct the all too common misinformation found on the Internet. ChatGPT is a useful tool however because it searches the entire Internet some of the information it provides is fueled by an incorrect statements already there.
