I had a sexual encounter about 50 days ago in Germany with a prostitute, who started performing oral sex on me without a condom. I did not realize it at first, but when I did after two minutes or so I stopped her. Thereafter I put a condom on and proceeded to have intercourse.
Since then I have however become paranoid ... read a lot on the internet... I have returned to Delhi, India yesterday and intend to give a sample for a HIV DNA PCR at a SRL center tomorrow. My question to you is, is the HIV DNA PCR test also senstive after 50 days ie. any good?? Of course I will have an antibody test done as soon as 3 months are over ... but I need to still the paranoia fist and therefore decided on the PCR test... Looking forward to your response... Arjun
Since the intercourse was protected, it might not be enough to pass on the infection. With respect to oral sex, transmission from a female to a male during oral sex is very less. There have been recorded cases of getting HIV from sucking or giving head BUT âthere have been no recorded cases of getting HIV from getting sucked.â Hence the overall risk of infection would be less.
But it is always better to get tested, so that concrete evidence of a HIV negative status will help to reduce the anxiety and stress.
Polymerase chain reaction (PCR) for proviral DNA (PCR -DNA) is a important test that can detect ââââproviral DNA during window âperiod, can âdifferentiate latent HIV infection from active viral transcription ââââand can quantitate the ânumber of HIV DNA. â
The DNA PCR is the absolute most sensitive test for HIV, and can be done anytime after 2 weeks post exposure. In case it is Negative, it will be definitive that you do not have HIV infection.
HIV DUO test, which is also called as a 4th generation HIV test, is a 100% âsensitive test, and it tests for both HIV-1/2 antibody and p24 antigens. Its specificity is 99.77% in individuals âat low risk for HIV infection. Hence it is a very accurate test for HIV screening. âThis test can be done at any time after 4 weeks of exposure, and will give a very accurate and reliable reading to confirm your HIV status.
Since it is already more than 7 weeks (48 days) since the exposure, it will be much economical for you to undergo a 4th generation HIV test, instead of a PCR test (which is expensive). There is no need to do a expensive test, in your case, since a very reliable test, like HIV duo test is available to know the same.
