Hi Mrs Anxious Thanks for contacting us. No, you don't need to get your results confirmed by your GP. If you have been in a monogamous relationship for 20 years and you and your partner have both got negative test results there is no chance that both test results would be incorrect. The BioSURE HIV Self Test does detect antibodies to HIV. Tests run by GPs are able to detect both antibodies and a product from the virus itself (the so-called p24 antigen). Directly detecting this antigen is only relevant if your potential exposure to HIV is WITHIN the last 3 months. After that time antibody tests are more reliable. So in your case the BioSURE HIV Self Test would be as accurate as any test that your GP could run for HIV. I hope that this answers your questions. Kind regards Gary Carpenter BioSure (UK) Limited
