A member asked:
Hi. is ecl hiv test for ag p24 a kind of western blot test? does that mean a negative of that after 75 days confirms the negative status ?
A doctor has provided 1 answer
No : Most often, p24 antigen testing is performed as part of a combination test that detects both p24 antigen and HIV antibody and is used to screen for and help diagnose an HIV infection. Occasionally, it may be used as an individual test to screen for early HIV infection, and may become negative as antibody develops (75 days). The more recent screening antibody testing is very sensitive and specific.
