Welcome to the forum. I'll try to help.
Everyting you say in the first half of your post indicates there was no appreciable risk from the exposure described. Intellectually, you seem to understand that there is no basis for being "sick with worry". The issue now is to find a way to let that intellectual understanding translate into emotional acceptance and relaxation about it. (My guess is that the main problem here, from a psychological standpoint, is that you regret the sexual choice you made. But don't confuse that aspect with HIV risk, which is zero for practical purposes.)
My advice is for you to be tested for HIV, as you are planning -- not because I believe you really are at risk. I do not, and from a strictly medical standpoint you don't need to be tested at all. But it seems you need the reassurance of a negative test result.
Let your doctor guide you about specific tests and when to have them. One option is to wait until the 8 week mark and have a standard antibody test. (Despite common advice to wait 3 months, it is really not necessary to wait that long for a reliable result; 6-8 weeks is fine). Or you could have a duo test, for both HIV antibody and p24 antigen; that test is 100% reliable at 4 weeks. Finally, you could indeed have a PCR test at this time, plus an antibody test at 4 weeks; that combination will also be 100% reliable. But no more so than the duo test, which would be a lot cheaper; PCR is costly. (If you have any of these tests at the 19 day mark, the negative results will be moderately reassuring. But for 100% reliable results you're going to need testing at the times I just suggested.)
You should also have a syphilis blood test, but not before 6 weeks. I recommend against blood testing for any other STDs; the risks are too low. You have already had negative gonorrhea and chlamydia tests; those results (even at 3 days) are completely reliable.
You could print out this advice as a framework for discussion with your doctor. Whatever testing you have, feel free to return with a follow-up comment to tell me the results. But since there is no point in speculating, let's not have any more discussion until then. In the meantime, stay mellow. There is virtually no chance you have HIV and you shouldn't be at all worried about it.
I hope this helps. Best wishes-- HHH, MD
No surprises, and no need for further testing at 6 weeks or any other time. Although the HIV antibody tests don't reach maximum performance until then, the combination of negative antibdoy at 4 weeks and negative PCR at 19 days is 100% proof positive that you were not infected with HIV. If you do any additional testing at all, a syphilis blood test at 6 weeks or later will meet the need.
Whatever you do, there is no need to post another round of negative results. That will be all for this thread. Take care and stay safe.
Just a quick rundown of my tests and results.
3 Days - Chlamydia and Gonorrhea - NEGATIVE
19 Days - HIV Qualitative DNA PCR and HIV-1 Antibody - NEGATIVE
19 Days - Hepatitis B-C, Herpes, Syphilis - NEGATIVE
28 Days - HIV Antibody (Rapid) - NEGATIVE
As suggested above, I will take another round of tests at 6 weeks.
So?
Fell free to report the test results here, If you wish. They will be negative.
I also saw my primary doctor this week. He performed another physical exam and said I looked good so far. Since I had the PCR test the day before, he drew blood and is running the standard STD tests and is checking my white blood cells. I should have the results tomorrow.
On Day 19 I went and got an HIV Qualitative DNA PCR test, and an HIV-1 Antibody test. The results came back today - both NEGATIVE. I know it's not conclusive but I am very relieved.
I plan on having an HIV Antibody test at 4 weeks.
Then at 6 weeks I will check for the other STDs as suggested.
Thank you. I will let you know when I get the results.
DUO is widely available in all parts of the country. If not done at a local lab, any doctor can always send a specimen to one of the major nationwide labs, such as Quest or LabCorp.
Thank you, Doctor, for taking the time to answer my questions. I very much appreciate the availability of a forum like this and the work you and the other doctors do. Over the past two weeks I've been pouring through the posts trying to gain some comfort. Your response has provided a great deal. If I had known this much about HIV transmission a few weeks ago I wouldn't be in this predicament. And you are correct, I very much regret this incident and that is not helping my mental state at all.
I neglected to mention that I'm in the US, the Boston area. Is the DUO test available in the US?
