Hi Vance, I just wanted to let you know that the gonorrhea and chlamydia tests both came back negative. It wasn't quite 7 days from exposure when I took the tests (it was 6.5 days), but it is now day 9 and I don't have any symptoms. Should I assume that these negative results are conclusive at this point? Dr. Handsfield seems to suggest that even 2-3 days is enough time.
Lastly, if I wanted to retest for syphilis just to be sure, would 4 weeks be conclusive? Some data I have read seem to indicate that 4 weeks is pretty conclusive in the absence of symptoms, which usually appear after 21 days on average. Thanks for answering all of my questions!! :)
I hate to break it to you but gonorrhea is largely spread by oral sex these days -- it easily spreads to and from the throat. Chlamydia is less likely unless she's a professional. I really wouldn't worry about syphilis; it is a rare disease. You'll need to wait at least a month for the syphilis test to be reliable anyway.
Hi Vance,
Sorry to bother you, but I wanted to ask you a quick question. It's been a week since the exposure and I do not have any symptoms (knock on wood). I did take the gonorrhea and clamydia test today (they combine them so I get both by default) and the syphilis test (I understand the syphilis test needs more time to be conclusive). If I currently do not have any symptoms (hopefully it will stay this way), should I have some level of confidence at the one week mark that my tests will be negative? I'll get the results in about 2 days.
Also, I read some info posted by Dr. Handsfield, where he lists the approximate number of days most people experience symptoms for the various stds that I could have been exposed to. Here is the reference post by him.
http://www.medhelp.org/posts/STDs/STD-Risk---Receiving-Unprotected-Oral-Sex/show/1200596
"Whether acquired orally or by vaginal/anal sex, the symptoms are the same: discharge of abnormal pus or mucus from the penis, sometimes accompanied by painful urination (gonorrhea, NGU); or penile sores (herpes, syphilis). Gonorrhea usually causes symptoms within 5 days, NGU 7-10 days, herpes 2-5 days, syphilis up to 3 weeks. If you decide to be tested even without symptoms, a gonorrhea test can be done reliably any time now -- 2 days after exposure is plenty. A syphilis blood test can be done at 6 weeks, and HIV testing could be done at the same time. I recommend against testing for HSV unless there are symptoms that suggest herpes."
I am not certain how big it is in India.
I see no reason for testing but if it helps you then by all means test.
Vance, sorry to bother you, but two last questions. Is India considered a 3rd world country where syphilis and gonorrhea are more prevalent? The woman I was with spends time in the U.S. and in India - not sure if she does the same thing in India, but she said she does nursing work in India (not sure if I believe that).
Based on the info in this exposure, if you were in my shoes, would you feel the need to get tested for gonorrhea and syphilis? Just trying to put my mind at ease.
Cancker to spread it.
6 weeks is conclusive, it's that simple. Typical is 21 days but up to 90 days and by 6 weeks the antibodies have developed.
Syphilis is rare in general. Only about 20,000 cases in America yearly. Most in gay and/or bi sexual men.
In the mouth-rare, in women-rare.
Thanks for responding Vance. With syphilis, does one have to have an open chancre sore to spread syphilis, or can syphilis be spread if you have it, even with the absence of an open chancre?
If I tested again for syphilis at the 2 or 3 week mark, would that be reasonably conclusive? I've read some posts by Dr. Hook, suggesting that in a low risk situation such as this, one could test for syphilis at 1-2 weeks and be reasonably confident of the result, in the absence of other symptoms and taking everything in context. I know this exposure is likely low risk, but I'm still nervous. Why do you have to wait 6 weeks to test for syphilis, yet chancres typically show up in 10-21 days? I'm not understanding this.
Is syphilis fairly rare in women, even women who will have unprotected oral with obviously multiple sex partners?
You really answered most of your questions. You are correct by just about everything you wrote.
No chlamydia risk. Syphilis is very very low and no such thing as a "baseline", you either have it or you don't.
I would not worry but if you think you have to test.
Gonorrhea-1 week
Syphilis-6 weeks
Herpes-3 months
