un protected vaginal intercourse
Ok Dr. I am extremely paranoid I had one too many drinks a lady took me home and she performed oral. Then we had unprotected sex for not even 2 minutes at the most. I am uncircumcized and and scared I have hiv. I asked her she said she had test 2 months before and was clear but had 1 other partner so her response was as far a s I know I'm clean. I'm paranoid I have 2 sons. She always had a 15 year old. How long do I have to wait to test in the us we don't have duo and they say the dna by pcr are giving false positives. I have a wife if I wear condom she will know please help dr. Thanks

This is getting silly. Each anser appears to just fuel your anxiety. This will be the last answer.
At 6 weeks 95% of persons with HIV will be detectable with standard HIV antibody tests.
Your risk is low because of the mathematical probabilities involved. Few people have HIV and the risk of infection is only 1 infection for every 1000 acts of intercourse. There is a less than 1 in 1000 chance that your partner had HIV unless she was an IV drug user. thus the mathematical chance that you got HIV is less than 1 in a million. That is low risk.
This ends this thread. EWH

At 4 weeks standard HIV amntibody tests will detect over 90% of recently acquired HIV infections.
In general we do not recommend HIV PCR testing for diagnosis is HIV infection for several reasons. While the PCR is likely to become positive more quickly than other antibody detection tests (i.e. usual blood tests), at the present time the blood tests are becoming more and more sensitive and detecting infection earlier and earlier so that the time difference in detection between PCR test and antibody detection tests is becoming smaller and smaller and at present is, in general only a week or two. In addition the time course over which the PCR tests become positive is less well described than for the blood tests and, as a result, it is difficult to make a definitive statement on what a negative PCR test means at any time within a few weeks of exposure to a HIV infected or possibly infected partner. PCR tests are also more expensive than regular antibody tests. Finally and most importantly, the false positive rate for PCR tests (i.e. a positive result in persons who do not have HIV) is higher than for blood tests. Each of this on this Forum have seen a number of people who were worried needlessly because of false positive tests. For all of these reasons, we rarely recommend testing for HIV diagnosis using PCR. At any time after 4 weeks a negative PCR is proof that you do not have HIV but there are the problmes I listed above to consider. EWH

Sorry dr didn't get response
I ask she wants nothing to do from me but dr. What's my percentage of knowing if I take a regular one at 4 weeks. And what do u feel aboul the dna by pcr how long should I wait or are they giving too many false positives

Welcome to our Forum. the statistical chance of your having HIV is low but to sure, using standard HIV blood tests you will need to wait until 8 weeks after your exposure to have a completely reliable test result. You can find out however MUCHG sooner if you can arrange to have your partner tested. If her HIV test is negative, then you can be completely sure that she did not have HIV. EWH
