Confirmation
Last year, I done the Biosure HIV test after 16 weeks of unprotected sex and the test came back negative. The person with whom I had the sexual interaction with, also claims she is negative but has not been tested. With all this being said I would like to know how sure can I be that my test is indeed negative? Given that I tested outside of the window period, I saw only 1 line after 15 minutes which means that it was negative and that I am not on medication such as Prep which could mask the HIV (only mentioning these things because I have read past posts that have mentioned that these are the reasons for possible false negatives that fall within the 0.01% of chance being a false positive when obtaining a negative result)

Hi Daniel,
Given that you tested 16 weeks post exposure, if you could only see 1 single line where the control line is positioned after 15 minutes then your result is negative. The clinical specificity of the BioSURE test is 99.9% which essentially means that on average every 999 results in every 1000 will be correct. This percentage takes into consideration the window period and interference from certain medication. Usually false negatives only occur when users test inside the window period or are taking PrEP or PEP, therefore I would say that your negative result is extremely reliable and conclusive - you do not need to retest.
I hope this helps, if you have any other questions please feel free to leave them below.
Kindest regards,
Becky
