I had a risky exposure (genital rubbing without full penetration) for 5-10 seconds and oral sex with a high-risk person. I did third-generation fingerprick blood test 10 times after five months at two weeks interval. After 182 days, I went to ICTC and did Comb Aids test and the result was negative. Is Comb Aids comparable to ELISA? How good is Comb Aids test? Are rapid kits in India reliable after five months? Please guide.
