75 days

about 11 week ago i had unprotected oral sex about 10 sec and protected vaginal sex. I took the test at 7 weeks, 8 weeks 9 weeks, 10 weeks, and last 75 days after the exposure and all result is negative. last 9 days for 12 weeks and just wondering what is the chance that it may become positive at 12 weeks? or do I need an other test 9 days later.

Hi Sumalee, The symptoms you have described alone are likely to not be related to HIV. Usually symptoms of HIV infection occur 1-4 weeks after exposure and are most commonly flu-like symptoms such as fever, headaches, muscle pains and weakness, fatigue etc. The fact that your exposure was protected would suggest that the risk of transmission was very low. Regardless, it is great that you have taken the initiative to test, given that you are unaware of your sexual partner's status. 7 negative results (albeit inside the window period) are very good indications of your negative HIV status however if you are using our test you must retest at 84 days (12 weeks) for a conclusive result. Your exposure was low risk and your negative result is very unlikely to change but you must still retest at 12 weeks for a conclusive result. I hope this helps to put your mind at rest, if you have any other questions or queries please feel free to leave them below. Thank you, Becky.

I had protected sex with a friend who I don't her status but am worried. I got tested 7 times and all were negative, but am still worried. I did my last HIV test in day 70 after the act and then found negative..but the thing is I am worried. My tongue is having bumps and some rashes - is this a sign of HIV? Will I be okay?

Hi nafyad. It depends on the test that u do. I think if you go for HIV-1/2 p24 4th generazion test it would detect almost 99% of infection at this stage. Having swollen lymp nodes doesn’t mean that u have hiv. It could be something else ailing u. It could either be a cause of anxiety. The best timing for the test to be conclusive is 90 days after exposure. Have u tested yet or no? If so plz let us know.

Hi Super Worry, unfortunately I am unable to comment on the accuracy of other tests so you may need to contact the clinic that carried out these tests in order to get an answer. If the self test that you carried out was BioSURE then these are all really good indications of your status - however, the BioSure test is only conclusive after 84 days (12 weeks). I would say to put this behind you as it is very very likely that your results are accurate but I can never say for sure that your result is conclusive until you test outside of the window period. Sorry that this is probably not the answer you were hoping for, but it would be wrong of me to advise you to not retest if you are still within the window period, even if it is a few more days. I hope this helps Francesca Bard, BioSure (UK) Ltd

Hello I had exposure 17/12/19. I took a 4th gen lab test after 21 and 45 days, all came back negative. Besides, I took self test after 47 , 72 , 74 days . How accurate all those tests are? I’m so worry!

Hi NAFYAD, if you wish to test before 12 weeks please remember that you will need to confirm a negative result at 84 days. This being said if your symptoms are a cause of HIV then this would produce a positive test result. The symptoms you have described could be due to many things and should not be over analysed to directly link with HIV, if these do not go down please visit your GP. I hope this helps but please don't hesitate to contact me further. Kindest regards Francesca Bard, BioSure (UK) Ltd

Hi TV, unfortunately I am unable to comment on the accuracy of the test that has been performed as I don't have enough knowledge or information on the test due to solely working for BioSure. I would recommend returning to the clinic where this test was carried out in order to get an answer to your question. Alternatively you could test using BioSure ( so that I am able to help you further. Kindest regards Francesca Bard, BioSure (UK) Ltd

Really thank you for the earlier response I did my 12 week hiv duo test and it came negative, but recently I got swollen lymph nodes in neck, apart of these symptoms I didn't have any other symptoms.Can you tell me how accurate is HIV duo test after 89 days. Is there any chance that hiv antibodies are been producing in my body after 90 days. Some websites says that HIV test after 6 months will be conclusive. Do I have to go for any other test further. Can you please answer it.

Hi Stress Freak Thanks for getting in touch. The chances of your test being a false negative at 75 days post exposure is about 2%. So your negative test result is extremely encouraging. To be certain of a negative result you would need to test again at 12 weeks after exposure. I hope that this helps. Kind regards Gary Carpenter BioSure (UK) Limited

I had safe sex with Csw which didn't lasted for more than a minute and it's not ejected properly. After that she gave me a oral sex. I did my HIV antibody test after 75 days and it came non reactive. Recently I am finding symptoms of losing weight, lost of appetite, and sore throat. I know after 3months the test will be conclusive. Is there any chance of test results will change.

Hi CEKEMENT Thanks for getting in touch. Your negative test result is extremely encouraging. The chances of a negative being wrong 11 weeks after possible infection is much less than 1%. Also, given the timing of the symptoms you describe and if they were the effect of an HIV infection, then by now you would definitely have created the antibodies required for the test to work. The chances of contracting HIV from single incident of oral sex with someone HIV positive is also extremely low, way less than 1 in 1,000. Given all of these factors I would suggest that your negative test results for HIV are conclusive and reliable, despite the symptoms you describe. I hope that this answers your question.

Hi Really Stress Thanks for getting in touch with us, we are often asked questions about the "window period", the time that a test may not pick up recent HIV infections. The issue is not so much with the test but the person testing. The bodies of people infected with HIV all react at times after infection. Most rapid tests, like the BioSURE HIV Self Test, work by detecting antibodies to the virus created by the body. The process of antibody creation can start from as soon as 24 days after infection (about 5% of people), but for some people that process doesn't happen until as long as 12 weeks after infection (99.99%). At 75 days the chances of a False Negative are about 2%. So your series of negative results are extremely encouraging, but can't be conclusive until 12 weeks after your exposure. I'm sorry that I can't be more conclusive than this. Kind regards Gary Carpenter BioSure (UK) Limited
