Hello, I had an Anti-HIV 1&2 test 7 weeks after exposure and the result was negative. I was wondering if it's conclusive. Thank you in advance?

HIV-post exposure: Seroconversion differs-If you test negative on an antibody test taken 3 months or longer after your last possible risk of possible exposure to HIV, you can feel safe in assuming that you do not have the virus.If for some reason you feel anxiety about relying on the 3-month result, you could opt to have another test again at 6 months. (Previous guidelines recommended Baseline/3mo/6mo/12mo/18mo). ...Read more

I had a oraquick HIV 1/2 oral test done two days ago. The results were negative. How accurate are those results? Last exposure four years ago.

Pretty accurate: According to cdc site, "in the clinical studies by the manufacturer, the oraquick oral fluid test correctly identified 99.3% of people who were infected with HIV (sensitivity) and 99.8 % of people who were not infected with HIV (specificity)." of course, if you have symptoms of viral illness or characteristic opportunistic infections, get the standard blood test for confirmation or denial. ...Read more

Likely negative: ELISA is highly accurate, almost 99%. So please be reassured. Repeat the test in four weeks or so to ensure it remains negative. If you have not been sick with a fever, rash, sore throat, enlarged glands, chills, night sweats etc. in the last two months, then the risk of being infected in last two months is even lower. ...Read more

No: It is recommended that you test also at 24weeks which would be 6months. Rarely does the test become positive after this but on a few occasions seroconversion had taken up to a year to occur. Get a counselor knowledgeable about the disease to talk to. This will help your anxiety level and use adequate protection in future ...Read more

I went for HIV test which is HIV 1/2 & p24 Combo test (CMIA) on 32 and 41 day of my last exposure, report says non reactive. Is this 100% conclusive?

Nearly so: For a definitive answer you should get a HIV nucleic acid test done at 12 weeks after the exposure. If that is negative that will essentially rule out HIV infection. Even the combo test, if negative at 12 weeks would be strong evidence against the infection. ...Read more
