HIV Biosure testing accuracy/confidence

I have not had unprotected sex in 6 months and have tested using the biosure self test today I received 1 clear line which demonstrates a negative result. Can I rely on this? How accurate is the biosure test? I am worried that I may not have performed the test correctly, can this happen?

Hi Becky I would like to thank you for clarifying for me. I shall move on with my life following this negative conclusive result as you’ve confirmed for me

Hi Concerned Pete, Sorry for not getting back to you sooner. Yes as long as the control line is visible then your test has been performed correctly and your result is accurate. The buffer functions as a suitable environment to allow the test to run properly. It allows the ideal pH environment for sample binding and even acts as a disinfectant for the sample. If water is used instead of the buffer solution it is unlikely to produce a control line, regardless the result would be invalid. If you were to be infected with HIV 6 months ago, the test would be able to accurately detect the presence of antibodies. Our self test has a window period of 12 weeks to allow every individual to produce enough antibodies for the test to give an accurate result. The fact that you have tested around 6 months post exposure - your negative result is accurate and conclusive. I hope this helps. Kindest regards, Becky

Hi again, further on from my last message I am asking if there can be errors and the control line to still show yet for no antibodies to be picked up/shown. I just want to understand if I can take my result as conclusive and no requirement for further testing. Thanks

Thanks Becky. So as long as the control line shows up the test was performed correctly? Would there be instances where the control line would should up even if the user did not perform the test correctly (say using water as an example). I carried this test out 6 months after exposure. Would I definitely be showing antibodies by now if I did have HIV?

Hi ConcernedPete, If your last possible exposure was 6 months ago, your negative result is reliable and conclusive given the time since exposure. The BioSURE HIV self test is 99.7% accurate. You should not worry about performing the test incorrectly as you say you have received a control line. Our test has a built in sample control line which essentially means that if the test itself was faulty or you had not performed the test correctly then the control line would not show and it would be very clear to the end user that the test has not worked properly. I hope this information helps. Thanks, Becky.
