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.

Thank you for your question.
If you tested 3 and a half months after you had unprotected sex and did not expose yourself to HIV during that time then you are HIV negative. The white patches on your tongue could be a result of many different things and it is important you go to your doctor about this.
Hi,
On 23rd October 2009 I had vaginal sex with a woman that I paid to have sex with me without a condom. 3 and half months later I took a HIV-1 and HIV-2 test. Both came back negative on 12th February 2010.
A few weeks after testing I found some white patches had developed in my tongue, is this a symptom of HIV? Is there any chance I could be HIV positive 3 and half months after I had unprotected sex?
Depends on the type of tests they have used. There is more information on testing and modes of transmission at the following link: http://i-base.info/qa/faq/hiv-transmission-and-testing

It makes sense to test again. There is information on testing and modes of transmission t the following link: http://i-base.info/qa/faq/hiv-transmission-and-testing
I have just recently gotten an HIV test. The doctor told me of course 3 months is when the “window period”. Anyways, it’s only been 2 months since I have had unsafe sex. And my test was negative, but now since I’ve heard about that it should be 3-6 months I’m wondering, should I go back and get tested again?
Most probably it is. There is more information on transmission and testing at this link: http://i-base.info/qa/faq/hiv-transmission-and-testing
I was tested for HIV 80 days after intercourse (vaginal) the results were Negative. this was just 11 and a half weeks is that accurate???
Having vaginal sex without a condom is a risk for catching HIV.
The first test result does not mean you are HIV-negative, because this is too early for HIV to be detected, even if you had become infected.
You need to test again if you want to know your HIV status. Some tests are sensitive at detecting infections after two months, and some recommend three months.
Ask your clinic for advice on the recommended period for the test they are using.
Dear Sir,
I had sex with a massage girl on November 1, 2007. I removed the condom from my penis 3-5 minutes before finishing the sex (vaginal sex). 15 Days after the exposure, I got HIV test and the result was negative. My questions are:
1. Does it mean that I am really HIV negative?
2. Should I get HIV test again in December 2007?
