Thanks for your kind advice . I will do test after 90 days . but I have seen in some post . P24 antigen test catch infection at early stage
"Finally, it is almost impossible that you have HIV in light of negative tests for both HIV antibody and P24 antigen at ~2 weeks after exposure. (India is a medically sophisticated country. The tests used and their results are just as reliable as anywhere in the world.)
The time frame of 3 months until completely reliable testing is standard advice. But it is hyper-conservative. The modern HIV antibody tests almost always are positive within 6 weeks. And as I said above, the combination of negative antibody and negative P24 antigen at 16 days is highly reliable. "
"So in general, p24 antigen is formed slightly before antibodies are forming allowing us to close the gap between infection to detection time - the HIV window period. As time goes on, then the majority of newly infected HIV positive people will form antibodies to HIV 1 or 2 by 28 days. In combination then, looking for both the HIV 1 p24 antigen and also HIV 1 and 2 antibodies will allow for much earlier detection of HIV than looking for HIV antibodies alone.
28 day onward testing negative is conclusive!!!!
Why tell people to go on stressing for 12 weeks that is outrageous!!!!"
Thats why I am confused . On 90 day I will be tested by ELISA Method
