Accuracy of HIV 1 & 2 AB and P24 AG test in 45 Days

[smpr]

Dear Doc.

First i want to say thanks to all the doctors, I had a event about 55 days before and I got tested in UAE for HIV 1&2 AB and P24 AG test I dont know about the generation. But both came negative and the doctor said you dont need any more further testing. I have few questions

1) Is this HIV combo is relaible / Accurates in 45 days (If yes how much %)
2)IF antibody is not detectoble it will detect antigen rt ? is there any case that antibody and antigen will not be able to dectectable after 30 to 40 days of exposure?
3) Is this p24 antigen test will detect HIV 2 Antigen also ?
4) why few people are putting 3 months time ?

I am hoping for your response

Thanks

sorry i may be not right to ask question here but i got the similar questions for Duo / Combo Ag/Ab test

if someone forms Ab later like at 48days, the Duo test still possible to detect the Antigen from 42-47days? i just wonder whether if antigen will not be detectable after there is enough antigen form or as someone said it will not detectable after 24days?

thanks

Hello

I agree you dont need any further testing.

The testing you had on the 48 or 49th day is entirely adequate and correct.

You are correct to say that the p24 antigen will test only for HIV 1 which as you know is the overwhelmingly dominant form worldwide. HIV 2 is very unusual even in its area of highest incidence (West Africa) but well over 99% of people will form antibodies to both HIV 1 and 2 (if exposed) by six weeks or 40 or so days.

I am happy that the test will have conclusively ruled out either HIV 1 or 2 by 48 or so days.

best regards, Sean
