[Question #5788] Testing accuracy with anxiety about results

22 months ago
Hello Experts, 

I need some clarity here. I have spent an ridiculous a amount of time reading about this subject and clearly have anxiety over it. 

In the beginning of June, I had mutual oral unprotected oral sex with another man with no ejaculation in each other’s  mouth. I’m very paranoid about the situation now as this is something I normally do not engage in.

16 days post event I took the Aptima RNA HIV test: result negative 

39 days post event I took the Alere Determine Ag/Ab finger prick 20 minute test: Result negative 

48 days post event I took the Alere Determine Ag/Ab finger prick 20 minute test: Result negative 

Last week I went to see my general care doctor and he ordered a full STD Panel to help out my mind at ease. Test result pending...

Both clinics where I took the RNA test and where I took the Alere both informed me  that my risk was very low to begin with and I should feel comfortable at this time that I am negative.  However I’m still having major anxiety over the issue and am very nervous about the next test results. I have also read everything I can find in the internet, but I would like to here from an actual expert on the subject. 

I appreciate your feedback!

Welcome to the forum. Thanks for your question.

HIV first:  This was a low risk event, because HIV is extremely rarely transmitted by oral sex. One set of risk estimates, from CDC, is that if a partner has HIV, the average transmission risk for a single episode of oral sex penis to mouth is 1 in 10,000; and from mouth to penis 1 in 20,000. Those numbers are equivalent to performing BJs on infected men once daily for 27 years, or receiving BJs by infected men once daily for 54 years, before transmission might be likely. And you don't know your partner has HIV, so your risk is even lower. For various reasons, even these risk estimates might be too high. Second, the combination of tests you have is 100% conclusive and proves you did not catch HIV. So all is well in that regard, nothing more to worry about, and no need for further HIV testing.

As fior other STDs, without symptoms, the chance you were infected is low. But it would be helpful to know exactly what tests you had. Proper testing would include a blood test for syphilis and urine and throat swab for gonorrhea and chlamydia. I would have recommended against any other tests. Let me know when you have the results -- but stay relaxed in the meantime. You definitely can expect all to be negative.

I hope these comments are helpful. Let me know if anything isn't clear.

Thank you Doctor,

I very appreciate your reply and this forum that you provide, it’s wealth of information from true experts!  

 The tests my General care doc order was just a STD panel of blood and urine. Not sure of the exact test names. 

I’ll follow up once I have those results.

Enjoy the rest of your Sunday!
