Window Period

The guy I had unprotected sex with got tested last week (May 1st) and his result was negative.  However, he told me that he had unprotected sex with one guy in February and one guy in March.  Can his result be reliable?  What is average time for someone to produce anti-body?  Thanks

No, those are not ARS symptoms. If you have a concern see your doctor. You cannot be diagnosed over the Internet.

It's been 2 weeks and 2 days after my exposure.  I started feeling pain on my right shoulder (on and off) since Sunday, sore right hand muscle, and tingling on my right hand today.  Can these be ARS symptoms?  I also have thick white deposite on my tounge which I had for many years.  It also started to concern me.  Can all these be symptoms of other STDs?  Please, help.

Just for the record I never told him that the p24 test would be definitive at 28 days, just that it would be encouraging

A P-24 and a PCR-RNA tests are a waste of money and are not stand alone tests. Just go get a Rapid antibody test at 3 months post exposure and you'll receive your conclusive result.

It would be better to go to a doctor since he can order the specific p24 or the 4th generation test, anyway I dont live in th US and I dont know but Im pretty sure that in San fransisco those test are avilable.

I live in San Francisco.  Do I need to see my doctor first in order to get tested for a duo or p24 antibody test?  Would Labcorp offer me the tests without seeing doctor first?  thanks

Where do you live? and the best day to test for a duo or p24+antibody test is at at 28 days.

4 weeks is 85% accurate for antibody test right, not PCR?  Today is 15 days after the exposure, so it means I should wait 13 more days (May 21st) to get DUO or fourth generation test?  Where/how do I find places offer DUO or fourth generation test?  Thank you.

RNA PCR are NOT recomended to routine scrennening since they have a 2%-9% false positive rate, cost and other technicall factors, at 4 weeks the test would be 85% accurate, at 6 weeks 95%,, you can get a DUO test or forth generation test at 28 days and it would be more than 95% accurate by that time, if you are after the 4 weeks then you just have to wait 2 more weeks to the 6 week test, and then you have to test at 3 months to get a conclusive result.

Thanks, sippets69.  If I heard you correctly, there is a 90% chance that anti-body will show up in test result after 4 weeks of exposure?  

to all,

Do you recommend RNA PCP, Elisa test if I want to know my result earlier?  I heard there are many false-postive results associated with PCP test.  Also, how do I cope with anxiety and stress before my 6 weeks test?  I slept less and woke up a lot thinking about my risk lately.  Please, help.  Thank you.

If he penetrated you unprotected it does palce you at risk from hiv and other std (No penetration = no risk) you cant trust 100% some one else word about their status your sex partner had several unprotecetd exposures so he would be at high risk, your symptoms have nothing to do with hiv, anyway a single unprotected receptive anal intercourse has a risk per act of 1/200 so the odds are in your favor. get tested at 6 weeks for a 95% accurate result and at 3 motnhs for a conclusive result.

ALWAYS USE CONDOMS

Good luck

Thanks.  This happened two weeks ago.  I did not let his penis pass my anal canal (the muscle that controls) when he tried, and we did this kind of foreplay for about 1-2 minutes.  Then, he withthrew.  He did not ejaculate inside me.  But, I am still very worried that I might get infected.  I have a very mild cold and running nose after 3 days and neck pain about 10 days later.  Are these symptoms?
He told me that the two guys he had unprotected sex with told him that there were hiv neg.  But, I am still so worried, and 3 months to get tested for a more reliable test seem so long.  What should I do?  Please, help.

The answer is no. A conclusive test is 3 months post exposure. HIV is not a guessing game. If you had unprotected sex with him you will need to test 3 months post exposure to obtain a conclusive test result.

the rough theoretical estimates put seroconversion at 50% by 2 weeks, 75% by 3 weeks, 90% by 4 weeks, 95% by 6 weeks, 99% by 8 weeks.
