Question
Is a negative test after three months accurate?
16 January 2018. Related: All topics, HIV testing, HIV transmission.
Hi, I had sex with a girl. Five weeks (37 days) after the exposure, I got HIV test and the result was negative. 91 days after exposure I got HIV test again for confirmation, the result is negative.
My questions are:
1. Does it mean that I am really HIV negative?
2. Should I get HIV test again next December 2007 (6 months after exposure)?
Answer
Yes, after this time the results are very accurate.
To question #1: Unless you had another exposure risk during the 91 days period, then yes, the test shows that you are HIV negative.
To question #2: In very rare cases it takes more than 40 days for the body to develop antibodies to HIV that can be picked up by the test. That is why it is a good idea to test again three months after the possible risk, even though the chances of a positive result then are very small.

Hi Tshepo,
If you’ve has conflicting results you will need to have another test. If its possible ask to have a viral load test.

Hi Bongiwe,
False positives do happen. Therefore, if you are unsure of your status you should have another test.
I tested in January this year and it was negative. I’ve now just tested again and its positive. Could this be a false positive?
Hi Mike,
If you keep testing negative, then that means you don’t have HIV. Please see Q1 here:
