I had an unprotected anal sex 3 months ago. the last test was taken in 11 weeks after the intercourse, I am going to do the 3 months test tomorrow. However, i am injected the booster of HBV vaccination today. Do you know whether it would influence the accuracy of the HIV test? I am going to have a duo test tomorrow, whether the p24 antigen would become detectable due to the hbv antigen injected into my body on today?
Thank you sir. I got that. whether i can understand in this way? it is no different between the hiv antibody test and duo test after 3 months? Because the duo test also is able to detect the antibodies. Do you think the duo test's ability to detect the antibody is weaker than the traditional test? could you help?
The antigen test part of the DUO is only useful up to say,4 to 5 weeks after infection.
The test is still good after that, as it also looks for antibodies, and antibodies will always be present. So, at 12 weeks all you really need is an antibody test.
The DUO at and/or after the window period is a waste of money.
