Protected Vaginal Sex & HIV RNA PCR (Mr AB)


Hi Team,

Thanks for the wonderful job you are doing.

Please note my question below

I am 32 year old circumcised male and recently on my trip to Asia I had indulged in sexual activity and I wanted to know whether am I at risk. Following are the sexual activity

1) Protected vaginal sex using double condoms. After sexual activity I checked both condom and found them to be intact, that is no broken condom or no leakage etc.

2) Protected oral sex. I used single condom which never broke in oral sex.

3) There was absolutely no kissing or anything else involved.

4) I just touched her vaginal area ( only surface no insertion) once for few seconds and later I realized I had a minor non- bleeding cut on my finger. This cut was 2 days old and although bit deep seemed only superficial as there was never any bleeding.

At no time her fluids touched me except maybe during touching her vaginal surface or her fluid on my pubic hair.

I have already undergone HIV RNA PCR test on 16th Day after my sexual activity ( >2 weeks) and it came out negative.

Please let me know am I still at risk?



Thank you for your inquiry. From what we gather from the question, you were asking about the accuracy of a negative HIV RNA PCR test taken 16 days after engaging in protected vaginal sex, which is a Low Risk activity (evidence of transmission occurs through these activities when certain conditions are met).

The scenario mentioned above does meet the three components of the Transmission Equation. It was very responsible of you to access HIV testing after these activities, as the improper use and potential breakage of condoms could lead to HIV transmission. The HIV RNA PCR test, also referred to as a HIV nucleic acid amplification test (HIV NAAT), has the shortest window period of all the HIV tests and is able to accurately detect HIV infections as early as 7 to 14 days after infection (1). In order to be completely confident in the negative HIV NAAT result, a follow-up antibody test 12 weeks after exposure is recommended by most HIV specialists for completely conclusive results.

Recommendation: Refer to a physician for an HIV antibody test 12 weeks post-exposure
