Is a duo test conclusive at 11 weeks and 5 days post exposure. Also along with the duo I had requested an PCR RNA at 11 weeks and 5 days at the same time and both the results were negative. Which for me meant being negative on the antigen part and the antibody part and also the Viral load part. Is there any possibility of a positive later without any further exposure ?


The Duo HIV test that looks for both HIV antigens and antibodies has a window period of 50 days. The negative HIV tests you had at 11 weeks and 5 days means you did not get HIV from that exposure and there is no need for further HIV testing for that event. There would be no possibility of a positive later unless you had a new exposure.

Let us know if you have any more questions or concerns.
