A few months ago I had sex and then three days later, I went on Prep. The required test to receive Prep came up negative (because it was only three days since I had sex). I have recently taken a HIV test. It has been three months (since the above incident) and it has come up negative. I just wanted to know if taking Prep would affect my results in any way since I am still unsure about that incident I had just before taking Prep. If it does effect the results, how long do I have to wait until I receive a conclusive result. Thank you.

The vast majority of HIV tests are conclusive after three months following a risk incident. In fact, some HIV tests have a window period of six weeks or less. For absolute confirmation, touch base with your healthcare provider who did your testing to confirm window periods, while it is highly likely the test is conclusive.

Hello, Will being on Prep affect my HIV results in any way? Thank you

PrEP is only available to people who are HIV negative, so we shall interpret your question to mean, how will PrEP affect your HIV test results? PrEP, when taken as prescribed (in Australia that is one pill taken once daily), it extremely effective at reducing the risk of acquiring HIV. It is important to take one pill once a day however. If you miss doses, the effectiveness of PrEP reduces and puts your more at risk of acquiring HIV.

I had a non occupational exposure risk to hiv. The partner hiv status is unknown. I started pep 12 hours after exposure viread300 plus zeffex 300 for 28 days. Hiv p24 antigen only is done at 28 days post exposure and was negative. Hiv antibody (third generation) is done 6 weeks 12 weeks 14 weeks and 16 weeks post exposure and all came back negative As 4th generation test is not available where i live Can these results make me reasonably negative for hiv

How accurate hiv 1@2 antibody test 15 weeks after exposure

Most HIV tests are fully conclusive after six and twelve weeks following a risk incident, depending on the test used. The variance in window period depends on which HIV test your healthcare provider uses. To answer your question with certainty, ask your healthcare provider who delivered your last HIV test for those details. If you have never had a test, it is recommended to test four times a year and your provider will inform you of the specifics of the test used at your visit.

Hello. I had an exposure last November and I took a 4th generation hiv test at 8 weeks and a rapid hiv test at 15 weeks both were negative but my doc says the hiv period is 6 months. Now I am really concerned because I am feeling unwell and I am in 5 months after my exposure. Should I be worried about my 6 min hiv test being positive.

Hi, thank you for the question. The window period for a HIV test is up to 3 months. So, unless you have had a risk exposure in the last few months it sounds like you should be outside the window period. You can learn more about testing here: https://endinghiv.org.au/test-often/all-about-testing/ It might be worth going to a sexual health clinic to have a sexual health check-up as they will be able to go into a lot of detail around the type of HIV test that they administer.

I had a guy try to stick his dick in me from behind, but it hurt so we stopped after he initially tried to stick it in. He had a fair bit of pre-cum and had put on a condom, but when I turned around immediately after the failed penetration, the condom was off. I've asked and he said he just took the condom off himself AFTER he tried to fuck me, but I'm not 100% sure if that's the truth. Given that there was little to no penetration (or only very briefly) and that he produces a decent amount of precum, is there a risk of HIV transmission? I was tested about 18 days after this, but I understand this falls in the window period for HIV testing (i had a rapid test, and a full blood test at SSHC, which came back negative)

Hi, thank you for your question. If there was no penetration, this would be considered low risk. However, given that it is hard to tell what happened, we aren’t able to give you conclusive advise. It was really good that you went and had a sexual health test, and we would recommend that you have another once you are outside of the window period. It could also be worth talking to a sexual health nurse over the phone by giving the Sexual Health Info Link on 1800 451 624. They will be able to give you further advice, which may help.
