Detailed Answer:
Hi,
Welcome to ASK A DOCTOR.
Thanks for posting your query.
Almost all the HIV tests available in the market are reliable up to 97% or more after the window period.
HIV ECLIA is a 4th generation test detecting the HIV 1 Antigen and also the antibodies for both HIV 1 and 2.
4th generation tests are highly sensitive and specific and accurate up to 99%.(https://www.jcdr.net/articles/PDF/11877/35169_CE[RA1]_F(SHU)_PF1(AGAK)_PFA(AK)_PB(AG_OM)_PN(SS).pdf)
As far as the HIV 1 P24 antigen part is concerned, this test is reliable from 2 weeks after the exposure and becomes conclusive by 4 weeks. The antibody part of the test becomes conclusive by 12 weeks after the exposure in a normal immuno-competent individual.
In your case, as you had the nonreactive test 8 months after the exposure, you are free from both HIV 1 and 2 to the extent of 99%.
