40 Day Test Considered Conclusive?


Good day. I had my blood tested on a Laboratory on the 40th day since exposure. These were the activities that had happened.

1. Tongue Kissing
2. He rimmed me.
3. He blowjobbed me.
4. He fingered me.
5. Rubbing tip of his penis on my anus (not sure if there was a pre cum or not)

Should i still get tested on my 3rd month?

Thank you.


Hi there,

Thank you for your inquiry. From what we gather from the question, you were asking about whether you should receive further HIV testing beyond the HIV blood test you received 40 days post exposure (given the sexual activities that you have described above).

From the information given, of the activities described above, you appear to have engaged in Negligible Risk activities when it comes to HIV transmission (There is no evidence or no documented cases of transmission. However, there is a theoretical possibility of transmission under certain extenuating circumstances). To clarify, the activities that you engaged in do not warrant a significant risk, unless there were extenuating circumstances involved in one or more of each.

However, official HIV testing guidelines recommend re-testing at approximately 12 weeks post exposure to assure that you have received completely conclusive results (1). For this reason, we Recommend that you seek additional HIV screening on your 3rd month post-exposure, to assure you of your HIV status.

All the best,

AIDS Vancouver Online/Helpline, Cody
