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.
