HIV Duo Test - HIV 28 Day Test

HIV Duo Test - HIV 28 Day Test

The HIV antibody/p24 antigen Duo Test is an excellent, accurate and inexpensive HIV test that reliably detects HIV infection that occurred just 28 days prior to the test. This HIV test is known as the 'Duo' because it tests for both HIV antibodies as well as the 'HIV P24 antigen'. The HIV p24 antigen is a core HIV viral protein which becomes detectable at approximately 10 days post exposure, peaks at 16 days or so and then remains at high level for 8 to 10 weeks post exposure. It will then fluctuate over the rest of the course of the illness. HIV p24 antigen is extremely useful in combination with an HIV antibody test in determining early on whether an individual has been infected with HIV. The HIV DUO test is extremely accurate at 28 days and is now the test recommended by the new UK Guidelines on HIV testing 2008.

We send a small blood sample to our laboratory and the results are usually available in a few hours. The cost of this HIV test is £125 (all inclusive). The HIV DUO test including p24 antigen is rated as 99.8% accurate.
