I am a gay man who has been on PrEP since becoming sexually active. About 5 weeks ago I engaged in unprotected anal sex with someone. I was the top/insertive partner. He mentioned after the fact that he had a "blood disease" that is not transmissible, but he did not want to discuss it or name the disease. He was pretty evasive and basically just told me not to worry. I have been nervous about possibility of hepatitis exposure since. There was no obvious bleeding during sex, and it was not rough or vigorous. 

1) I have read that HCV is not considered a STD, but assuming I was exposed as the insertive partner, how risky would you consider this exposure?

2) I have read a few different things regarding the testing window. I have a doctor's appointment this week, which will be just 6 weeks after the possible exposure. Would a hepatitis test at this point be considered conclusive?

Yes

I hope that this information is helpful.  EWH

If allowed, I have two follow up questions that came to me after the original post.

1) In reading other threads on this site, it wasn't entirely clear to me whether or not taking PrEP might sometimes yield a false negative on 4th gen HIV tests at six weeks (I'm sure it's clarified in your answers somewhere, but I had trouble searching). Is that a concern, or would the HIV test also be considered conclusive at this point?

2) I started having sex, and PrEP, pretty recently and believe that I may have timed incorrectly at the beginning. It takes 7 days before PrEP is fully effective. Looking over the timeline, my first unprotected exposure (receptive) may have been after only 6 doses, but I continued taking it daily after. Would this increase the risk significantly enough to worry?

Taking prep irregularly during the first six days would only slightly reduce its effectiveness.

Ag/ab HIV test 57 days (8 weeks +1 day) after unprotected receptive anal following 6 prep doses: non-reactive

Hepatitis C Ab test 45 days following unprotected insertive anal: non-reactive

Thank you again!
