It is not approved to give a conclusive negative test earlier than 3 months post exposure.

THANKS ALL,

Based on the CDC guidelines, a test is conclusive at 3 months. But read the Drs' answers in the expert forum on this topic and you will get a better sense as to the reliability of a duo / combo test like yours at 4 weeks. If I were you, I wouldn't worry. Stay safe.

yes it's accurate and conclusive. it is approved for use anytime after 28 days.

I don't know what lab you went to by they were incorrect. There are no tests marketed or sold to give a conclusive negative test result earlier that 3 months post exposure.

i just came from hospital now. i was with my wife to do a pregnancy test. i asked the lab about hiv combo test p24. he told me after 4 weeks its concludive  anx after six weeks it will not change. he is working in lab from 6 years. so now am confused. :)

"and can i consider this stupid 8 weeks p24 4th gen final?"-Do you have troble reading? Because I clearly said 3 months is conclusive.

Symptoms or lack of are never going to tell you anything in terms of HIV.

well i have something else, after my incedent i slept with my wife without condom, after that by 8 weeks i tested negative in p24 and Eclia antibodies test. now my wife for the first time she was waiting her period and it didnt happened ( its late 6 days) she did the test of pregnancy at home and no results. she had a normal flu for 4 days from 3 weeks then after that she had infection in her middle ear and she took madicine ( anti biotics). as i was searching on the net i saw that hiv symptoms on women are menstrual irregularities!! i was shocked because at that time i belived my 8 weeks results and and i planned to get a baby. now am confused. is menstrual irregularities is an HIV sypmtoms for women? and can i consider this stupid 8 weeks p24 4th gen final?

also by the way i did HIV 1 & 2 Antibodies before doing this test by 5 days = 7 1/2 weeks, and it came also negative

[killer_1]

but this test is Antigen and Antibodies, so if antigen is not available it will search on antibodies or am wrong?

[Vance2335]

3 month antibody test is conclusive. 8 week test is unlikely to change. The antigent part of the test is meaningless after about 4 weeks.

thanks lng07, but you mean yes its accurate and conclusive at 8 weeks or yes its useless at 8 weeks?

[Lng07]

yes.it does not lose it's accuracy with time.
