HIV PCR can pick up the presence of infection as early as 7 days. But it can be considered as conclusive only after 3 to 4 weeks after the exposure.
Similarly HIV COMBO test antigen part can detect only HIV 1 infection and not HIV 2 as with HIV PCR, whereas HIV 1 and 2 antibody detection can be reliable only after the window period and not earlier.
3 days PEP can have some influence on this test and can delay the diagnosis still further. The possibility of HIV 1 infection had been ruled out to an extent in your case.
Hope I have answered your query. Let me know if I can assist you further.
Regards, Dr. S. Murugan
