Question 1

elisa p24 antigen 1.56(s/co) positive, antibody negative@25 days after exposure. rna pcr tnd(target not detected) @25days. elisa p24 ag 0.92(s/co) (gray zone)@27 days. roche eclia hiv ag/ab combo test negative @30 and 35 days. am i infected or not?

Accepted Answer

: Almost certainly you had a false-positive intial p24 antigen test, which later was negative, as shown by the negative AgAb tests at 30 and 35 days. You do not have HIV. However, it can take up to 45 days for AgAb tests to become positive. Have another AgAb test 45+ days after exposure.

Question 2

hiv p24 ag ab combo test at 28 days, 42 days and 62 days, some are negative.quanto to be safe after 62 days?

Accepted Answer

Not a good test: P24 antigen testing is not the best way to rule out infection. The most sensitive test is a qualitative viral dna test, not usually performed. At 62 days HIV elisa may well be positive, if you were infected. Because sometimes antibodies are not formed until 90 days, you can complement by HIV RNA test that can detect down to 20 copies per ml of blood.

Question 3

i had a hiv ag ab combo 4th gen test done at 3 weeks 6 weeks and 19 weeks are they conclusive still very scared?

Accepted Answer

4th gen HIV tests...: ...are 100% conclusive any time 4 weeks or more after exposure. There is no basis for continuing to be frightened you have HIV.  Assuming you haven't been reexposed more recently, your 6 week result was conclusive and your 19 week test unnecessary. Stop testing and do your best to move on without worry. Also test for gonorrhea, chlamydia, and syphilis if not done, much higher risk than HIV.
