HIV diversity and tests

Hi, several years ago I had high-risk exposure (condom tear) while on holiday outside of UK. The female was of African origin. I say this without prejudice, but obviously from an area of the world with higher HIV rates, and as I have since found out, a high diversity of HIV groups, strains, and subtypes e.g.Hiv2, group O, group n, etc. My understanding is that group n and p are very rare (few hundred cases), so will maybe rule those out, but does the biosure test for hiv2 and various hiv1 subtypes, crf’s, and group O? I have taken 2 biosure tests, both negative, and a 4th gen test at hospital (all well outside window). Because of the type of risk, do I need a more specific test? I am very worried they may miss infection as had lots of symptoms. Is there any literature on what subtypes/groups the biosure test covers? Many thanks.

Hi anonanon01, Sorry for not getting back to you sooner. The BioSURE HIV Self Test is able to detect antibodies to HIV-1 and HIV-2 including all subtypes/groups. Since your exposure was unprotected it was a good idea to test. You do not need to do a more specific test; your negative results outside of the window period are confirmation that no transmission occurred years ago. I hope this helps. Kindest regards, Becky

Hi, I appreciate this is a technical question, but is there any reason this has not been answered? All I need to know is are the biosure tests safe to detect various types of HIV? And possible exposure outside of UK? Many thanks.
