What This HIV Blood Test Includes
Blood Test
This checks for antibodies produced by the immune system in response to HIV-1 infection.
This checks for antibodies associated with HIV-2 infection.
The p24 antigen is a viral protein that may become detectable before antibodies are fully produced, helping reduce the HIV testing window period.
Why Choose This Private HIV Test?
