Detailed Answer:
Welcome to XXXXXXX
Thanks for posting your query.
HIV antibody tests detects antibodies against HIV. Body will take some time to produce antibodies against HIV inside our body it is infected with HIV. That time interval is called as window period. For HIV infection the the window period is around 8-12 weeks. So if the test done after 12 weeks or 3 months then the test becomes reliable up to 97-98% as the tests marketed are highly specific. When repeated with another type of antibody test then the specificity goes up to 100% when the are put together. When there is a controversy between these two results a third test is preferred.
