Is the HIV swab test accurate two weeks after sex?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 32-year-old male who recently had a sexual intercourse with a female but got interrupted after one minute. This was approximately two weeks ago. I did not use protection and I did not ejaculate. I am very worried because she told me after sex that she once tested positive for HIV. I asked her what do you mean once. She said that she was not positive after being retested. I found that very strange for her to share with me. I did not know her very well so I began to worry. I know two weeks is too early to check for antibodies but my question is what are the chances of HIV transmission assuming she is positive?

Today I took an Oraquick swab test just to calm my nerves. I know you have to wait a month or more. But I cannot stop worrying. Does a swab test provide any accuracy at two weeks? I also went to a nearby clinic to receive an RNA blood test today. How accurate is an RNA blood test post two weeks of possible exposure? I am very worried that I cannot sleep or eat until I get a solid result. I have been highly stressed and it is affecting my life in and out of work. I do not know what to do or think or who to talk to. I appreciate any help or advice you can give. I am worried and stressed.

Hello,

Welcome to icliniq.com.

First, the chances of transmission of HIV, it is less in males when compared to females. Because the receptive area of males is very less than females. As you have interrupted within a minute the chances are even low but can't be ruled out. If we take an average the chance in males is 50% less than females. It differs accordingly to different studies. At this point, It is of no use in thinking about the chances. At this point, we cannot detect the antibodies in the blood. Get an RNA blood test which will be detectable by this time. Now you get the RNA tests and if it is negative we can rule out HIV with more than 90 % accuracy. If it turns out to be positive then you start immediately on a post-exposure prophylaxis regimen.

Thank you.
