How soon can a person test positive for hiv after exposure? Will a negative result after 6 weeks change after 12 weeks?

It takes time for HIV to be detected in the body. Most people who’ve been exposed to HIV will test positive within one month after exposure, but a small number of people take up to three months. This period is known as ‘the window period’. The window period is the time between HIV infection and the production of antibodies; a lot of HIV transmission occurs because guys don’t know that they have HIV developing in the window period. So, if you test negative at three months after your potential exposure to HIV, it will almost always mean you do not have HIV, if there has been no risk of transmission in the meantime. However, if you’ve continued to be sexually active then you will need to get tested again. We always recommend confirming the window period of your tests with your provider. If you’re getting tested within the window period, you will need to get tested again after the period for a conclusive result for your HIV status. We recommend to people who are sexually active to get tested for HIV and STIs 4 times a year (every 3 months) with their doctor or local sexual health clinic.

Hi and thanks i am in australia and was tested 4 times for hiv the first test at about 2 weeks then about 4 weeks then 7 weeks and 2 days and then at 3 months 2 days for hiv and all came back negative would that be classed as conclusive

Your HIV test results are accurate and conclusive if you were tested outside of the window period (12 weeks after the potential exposure). This will not take into account if there has been a risk of transmission since then. If you’ve continued to be sexually active, you will need to get tested again. We recommend to people who are sexually active to get tested for HIV and STIs 4 times a year (every 3 months) with their doctor or local sexual health clinic.

Im a boy and I had oral sex with a girl, after sex I have been tested for hiv 1 and 2 months and my results is negative. Should I be worry about it? And today is 90 days and Im going to test again, is it enough 90 or I should wait until 180 days ???

Oral sex is very low risk for HIV transmission. This risk can increase if there is cumming in the mouth and cuts and sores are present, though this risk is still considered quite low. The risk for other STIs to be transmitted during sex can be different. We recommend to anyone who is sexually active to test for HIV and STIs four times a year (every 3 months) with their doctor or local sexual health clinic. Your HIV test results are accurate and conclusive if you get tested outside of the window period (12 weeks after the potential exposure - or as you have written, at 90 days). This will not take into account if there has been a risk of transmission since then. If you’ve continued to be sexually active, you will need to get tested again. We recommend to people who are sexually active to get tested for HIV and STIs 4 times a year (every 3 months) with their doctor or local sexual health clinic.

Hello i had an exposure 87 days ago i tested negative with a rapid antibody test at 83 days should i test again ?

Hi there, thanks for your question. It takes time for HIV to be detected in the body. Most people who’ve been exposed to HIV will test positive within one month after exposure, but a small number of people take up to three months. This period is known as ‘the window period’.

However, if you’ve continued to be sexually active then you will need to get tested again. We always recommend confirming the window period of your tests with your provider. As you’ve been tested within the window period, you will need to get tested again after the period for a conclusive result for your HIV status.

I had sex with an hiv positive female unknowingly to me @ the time at four weeks i got an hiv antibody/antigen test done is that accurate or should i be worried i did use a condom

Hi there, thanks for your question. If you used a condom, then that would have greatly reduced your risk of any HIV transmission, however for anyone who is sexually active we'd recommend getting tested for HIV once every three months. It takes time for HIV to be detected in the body. Most people who’ve been exposed to HIV will test positive within one month after exposure, but a small number of people take up to three months. This period is known as ‘the window period’.

However, if you’ve continued to be sexually active then you will need to get tested again. We always recommend confirming the window period of your tests with your provider. If you’re getting tested within the window period, you will need to get tested again after the period for a conclusive result for your HIV status. We recommend to people who are sexually active to get tested for HIV and STIs 4 times a year (every 3 months) with their doctor or local sexual health clinic.

I got a test done 4 weeks after contact, it was negative. How accurate is this result?

This depends on the type of test. Depending on the test, HIV can have a window period of up to three months. Even the most advanced tests available today are generally only considered conclusive after around 6 weeks. If you are unsure about the window period of your test, we recommend confirming with your test provider. If you’re getting tested within the window period, you will need to get tested again after the period for a conclusive result for your HIV status.
