Is The HIV RNA PCR Test Conclusive After 10 Days Of Exposure?

Posted on Fri, 24 Jul 2015

Question: Hello doctor , sorry to bother you again .
I asked you a question a few days ago regarding my situation.
I had unprotected sex on 6th XXXXXXX (only vaginal sex and my first and only unprotected sex) the girl had multiple partners before ! She does claim to be clean and uninfected by anything. Her last unprotected sex was on 15th feb (I AM NOT SURE IF ITS 100% true) . She took the rapid hiv antibody test on 9th XXXXXXX and it was negative.
I took the qualitative hiv rna test on 10th day post exposure ( precisely 9 days and 12 hours ) .
Negative
I took a rapid hiv antibody 1/2 test on 24th day( negative ) .
I know both my tests are in the window period .
You previously said that the rna tests are 99% accurate at this point but i dont know why reading posts from other doctors on the same website i am getting different answers and beliefs.
Im gonna take the duo test on day 30 but i am just bothering you again out of anxiety !
Thank you !

Welcome to health care magic.

The person is HIV negative after 3 months exposure .It is conclusive and she is negative. So the chances of transmission of HIV from her is nil.
You can allay fears .
HIV RNA PCR is 99% sensitive after 10 days exposure.Usually only HIV 1 detection is done in PCR. HIV 2 is very rare. You are free from HIV.
So you can allay fears of HIV.
