Hi Mackenzie, The fact that you have done six tests since your exposure in March and all were negative, is a good indication of a negative status. However, you are still in the window period so I cannot say for certain that you are HIV negative. Your result is unlikely to change but I cannot say for sure as you have tested within this period and false negatives are most likely to occur when users test within the window period. The BioSURE HIV Self test has a window period of 12 weeks so I would recommend testing in another 6 weeks from today (21 April) just to be certain as your result would only be conclusive 12 weeks post exposure. I hope this information helps, if you have any other questions, feel free to leave them below. Kindest regards, Becky

Hello, i have an exposure on unprotected sex on 10th March. I tested 20 days, (2 test. One Biosure and other, 28 days again Biosure and another and today at 41 days again Biosure and another.. All six tests are negative.. But my anxiety cant seem to let me settle down... What are my chances of turning positive later without any other exposure?

Hi Lonely22, I would recommend to be sure of the window period of the tests that you have taken. If your possible exposure was on the 30th of March and you tested on the 6th of April, that would only be a week and most HIV tests do not have such a short window period. This could mean that your result gave a false negative result. From the description of your possible exposure, there is a low risk given that he ejaculated in the condom but this is not to say that transmission did not occur, HIV can be passed through pre-cum for example. Given that, your sexual partner may not have been HIV positive, unless you know so. Regardless, it is great that you have taken the initiative to test but I would recommend to retest once you are outside of the window period. Most HIV tests have a window period of at least 4 weeks, so perhaps wait until the end of April and then retest using a suitable HIV test. I understand that this can be an anxious wait, but try not to over worry. Remember that HIV is now a treatable condition. I hope this information helps.
