Allay the fears of HIV.

Detailed Answer:
Hi
Thank You for query.I am Dr Bharatesh D Basti answering.
The chance of HIV infection by vaginal intercourse is 1/200 to 1/2000 even with an infected partner. Here in your case as it was protected, the chances are almost nil. So you can allay fear of HIV here only.

The RNA PCR is conclusive by 13 th day for HIV-1 and it is most common . So you can allay fears of HIV. HIV 2 is rare in XXXXXXX and do not worry.
Duo requires time to be conclusive and it is negative also.
So you can allay fears of HIV totally .

You can get back for any clarification.

Thank you Doctor,
I have read on lots of sites about RNA PCR & each of them have different window periods for the test. Scientifically what is the time frame under which RNA PCR can detect HIV in blood after potential exposure ?
I am very much confused now & i had did my RNA PCR after 13 days.

Brief Answer:
after 10 days usually

Detailed Answer:
Hi
RNA PCR can detect hiv material as early as 3-4 days of infection but usually they accept minimum days as at least 10 days post exposure. They remain positive forever once appears in blood.
So it is viral genetic material.
So you have done at 13 days so you can be sure of negativity.

Thank you
