Hi,
Welcome to HCM.
You had your HIV test 50 days after your high risk activity. Probably it would be a antibody based test. Window period for HIV is around 8-12 weeks. So it is better to repeat the HIV test once again to get a more conclusive result and rule out the least possibility of HIV 1 and 2.

Hello. Thanks for writing to us at healthcaremagic
An HIV test needs to be interpreted with respect to the time that has elapsed after a risky sexual encounter, to determine its significance in confirming or ruling out an Infection.
Antibody based HIV Tests(Rapid spot tests, ELISA) is the most common screening test performed for HIV detection. Most of the individuals who are infected develop detectable antibodies within a month of infection. It is performed earliest at 1 month and is repeated at 3 months. The reason being that some individuals may not have detectable antibodies as early as 1 month after infection.
Since your initial test after almost 1 and 1/2 of exposure is negative, therefore most likely you are HIV negative. However, this needs to be repeated at 3 months to cover for the window period of infection.
Certain other tests like HIV PCR RNA can detect the presence of viral DNA as early as 2 weeks after infection, therefore are useful in early detection of HIV infection.
HIV DUO/COMBO test (detects both Antigens and Antibody to HIV). The test has a high sensitivity of 99.8% at 1 month and therefore is fairly accurate in determining the HIV status as early as 1 month after possible infection.
Regards
