You can test 3 months post exposure for a conclusive test result.
I would advice you to do 'Fourth generation ELISA for HIV1/HIV2' in 6week after the exposure.
1) 4th generation ELISA is a DUO TEST (Antibody and Antigen Sandwich Test) .It actually looks for the P24 (protein) Antigen and Antibodies simultaneously.
2) P24 Antigen is almost always present in the body after acquiring the virus till the 4th week after infection and then it disappears .
3)Once the P24 antigen disappears,antibodies starts to show up.
4) ' Fourth generation ELISA for HIV1/HIV2' detects both P24 antigen and antibodies 3 weeks after the exposure.
5) HIV DUO test is said to be best at 28 days and 6 weeks after the exposure.
6) Fourth generation ELISA test sensitivity is >99.5% and specificity >99% to both B and non-B subtypes. If a person has taken the test at the 6 week post exposure.
So I recommended you to do 'Fourth Generation ELISA for HIV1/2' i.e HIV DUO test 6weeks after the exposure.But 12/13 week testing from any generation of ELISA is compulsory.
A negative results on 6 weeks by 'Fourth Generation ELISA for HIV1/2'
would mean that you would have extremely extremely....extremely low chances to be HIV + in 12/13 weeks .
Play safe .Always use condoms while having sex.I am not against having sex but we must responsible while enjoying it.
Always use condom properly and never share needles.
Best of Luck

any doctors answers? heard chances are near zero but just want to be reassured
2 thrusts and no ejaculation is unlikely to result in infection.
a test at 6-8 weeks post exposure will give you a good indication of your status...but follow up at 3 months for that conclusive result.
