Unprotected Sex rick after 9 month antigen & antibody test 100 % confirm result please information me



Thank you for your inquiry. From what we gather from the question, you were asking about the accuracy of your 4th Generation Duo test results 9 months after an unprotected sexual encounter, which is considered to be a High Risk activity (Evidence of transmission through these activities and is the majority of cases of transmission).

The 4th Generation Duo test is a blood test that looks for antibodies AND P24 protein antigens. It is commonly referred to as the "combination," "Combo" or "DUO" test. Fourth-generation HIV tests can detect HIV infection in 50% of people by 18 days after infection; 95% of people by 34 days after infection; and 99% of people by one and a half months after infection(1).

Most HIV specialists consider this "DUO" test conclusive at 6 weeks. However, official HIV testing guidelines still recommend re-testing at 12 weeks for completely conclusive results, when accuracy is 99.9%.

We understand that you took this test and received the results 9 months after a possible exposure. This means that your result was received after 12 weeks post exposure, when official HIV testing guidelines consider this test completely conclusive. This means that the result you received is considered completely conclusive, and has an accuracy of 99.9%.

Recommendation: Test result considered conclusive at 12 weeks. No further testing is required. Refer to your healthcare professional for any other health related concerns.
