What is the antigen?

What is the antigen used in the Biosure test? Is it a whole HIV virus – i.e. could you catch HIV from the test itself?

Many thanks for your reply. I was definitely being very neurotic! :)

Hi Jim Thanks for getting in contact. To clarify, the antibody detection is based on synthetic peptides that are representative of HIV surface proteins. The antigen used is not the whole virus. The device contains no viable animal material. I hope that this helps to clear up your query. Kind regards, Gary Carpenter BioSure (UK) Limited

Sorry for being so neurotic. To detect the antibody though you would need some sort of antigen for the antibody to bind to. I was wondering what that antigen was, and if it was in fact a whole HIV virus, or just a viral protein / part of a viral protein.

Hi Jim, I would like to start by saying the BioSURE HIV Self Test cannot give you HIV. Our HIV test looks for antibodies to the virus rather than the virus itself, this means our test does not detect antigens. I hope this helps but please contact me if you require more information. Kindest regards Francesca Bard, BioSure (UK) Ltd
