If positive: If the test is positive, it is conclusive. In a small number of infected people it may take longer for the test to become positive. Blood Banks defer potential donors for one year from the time of exposure. For all practical purposes if the nucleic acid test is negative at 6 months after exposure the person is free of HIV Nonetheless, it is estimated that the median window period for fourth-generation tests is 18 days, with half of all infections being detected between 13 and 24 days after exposure. While occasionally this period will be a little longer, 99% of HIV-infected individuals would be detectable within 44 days of exposure . It might seem that after the period in which p24 antigen can no longer be detected in the blood (around 4-6 weeks), the test behaves just like a stand-alone antibody test

The 4 th Generation test can detect the presence of this antigen HIV DUO test (4th generation test) has two different parts and therefore called as DUO. 1. P24 Antigen detection part: This can be considered conclusive by 3-4 weeks after the risky activity as far as HIV 1 detection is concerned. This P24 antigen part can detect only the HIV 1 antigen and not the HIV 2 The antibodies that the Duo test detects are not present until roughly four to six weeks post-exposure.

Fourth-generation tests are advanced HIV tests that look for HIV antibodies as well as p24 antigens. When a person contracts HIV, the immune system starts to produce HIV antibodies. This is the body's method of fighting the virus. The immune system produces these antibodies in response to p24 antigens When any HIV serological results come back as positive, typically a different test known as the Western Blot is done to confirm results. A negative result does not require Western Blot. I hope that clarifies any doubts you have.

The probability of a false-negative result is 0.01 at 80 days' post-exposure for third-generation tests and at 42 days for fourth-generation tests.
