[Question #2892] Orak HIV

40 months ago
Hello. I am a male that received unprotected oral (blow job) and had protected sex with a condom from a  female. It has been one month since risk of exposure and I tested negative with oraquick at 4 weeks.  My question is would you recommend any additional testing or would you have advised testing period for based on the risk or lack of risk. Also can a flu shot cause a false positive on an hiv test?

Welcome to our Forum.  I'll be glad to comment.  HIV is  rare infection and it is unlikely that your partner had HIV.  Even if she did, the events you describe were essentially no risk events for HIV.  There has never been a case proven to have been acquired from receipt of oral sex and condom protected sex is safe sex as long as the condom is worn throughout the sex act and does not break.  Your recent negative HIV Oraquick test provides still more evidence that you did not acquire HIV- at 4 weeks it would have detected 85-90% of recent HIV infections.

Had you asked me if you needed testing after the exposure you describe, I would have told you there was no need for testing.  Thus, I also feel that there is no medical need for further testing related to the exposure you describe. 

Finally, there is no evidence that a flu shot would change the outcome of tests for HIV in any way.

I hope that this comment is helpful to you.  EWH

Ok. One last question. This was a Oraquick oral test that I bought from walgreens. If it's 85-90% accurate at 4 weeks why does the instructions say conclusive at 12 weeks?

The instructions reflect the parameters that were used in the application for FDA approval of the test.  The 12 week figure is overly conservative.  Further, with any test for HIV, the proportion of infections detected change (increase) with increasing time since exposure.  Thus for the OraQuick, 85-90% of infections are detected at 4 weeks and over 95% are detected at 8 weeks and all by 12 weeks.

Let me know if this is not clear.  EWH

Hello. You last message was pretty clear. I went ahead and take another oraquick at 6 weeks just for extra accuracy and it was negative as well. My anxiety has risen again due to the fact that last night I had a drink in a glass and I let someone have a sip and then I drank from the same glass. I then rememberedthat I have a small cut at the bottom of my mouth around the gum area. My question is if the person that took a sip from my drink was hiv positive and had slight bleeding from the mouth ,could it  have gotten in or on my drink and then infect me through the cut in my mouth. I'm really worried and cant sleep.

It is important to distinguish between appropriate and inappropriate anxiety.  You do not know that the person you shared your glass with had HIV.  Even if that person did, the anxiety you describe above is unwarranted as HIV has NEVER been transmitted through shared eating or drinking utensils.   That you might have had a cut in your mouth is irrelevant.  HIV is transmitted ONLY through DIRECT sexual contact or injection of infected material deep into tissue.  Touching, surface contamination of skin which may or may not have cuts, and other casual contact does not transmit HIV. 

This is my 3rd reply to your questions.  Thus, as per Forum guidelines, this thread will be closed shortly later today.  Take care.  EWH
