I have been to the forum a couple of times in the past and have learned a great deal.  My question(s) this go around are more geared towards various STD testing and timelines.

I took your advice from several months ago and did not test specifically after any one event, rather waited a little more than a year and just did what I am calling an annual/yearly STD test as my exposures are limited to only oral sex (cunnilingus and felatio).

My questions:

I did engage a FSW exactly 3 weeks ago.  My yearly STD testing occurred on the 21st day as it happens after my most recent event.  The event 3 weeks ago: I received protected (condom) felatio and gave unprotected cunnilingus.  My tests which included HIV, Syphilis, Chlamydia and Gonorreah came back negative.  I know 3 weeks is too soon for HIV and Syphilis but am wondering how many infections do traditionally get caught by the 3rd week percentage wise for HIV and Syphilis?  I believe my other tests are fully accurate?  Would you advise I wait another 3 weeks and redo HIV/Syphilis or simply wait again for my next yearly screening as long as I limit to only oral sex (male/female)?

Second question.  For the Chlamydia test it says Chlamydia/GC Amplification Result.  I just wanted to confirm this result includes Gonorreah?

Third question.  Is there a time period where it is too late (meaning passed the testing window) to test for Chlamydia and Gonorreah?  Or will it always be an accurate test even if it's months later after a sexual encounter?  It was a urine test fyi.

Thats all I have for now.  As always, many thanks to you all for your expertise and this forum.

1) The HIV AgAb (4th generation) blood tests are positive by 3 weeks 80-90% of the time. Syphilis probably a bit lower, maybe 60-70% reliable at that time. So those negative results should be reassuring but are not conclusive. The negative gonorrhea/chlamydia results are conclusive, as discussed in your earlier threads.

2) GC is shorthand for gonorrhea (from gonococcus, the gonorrhea bacteria). You have neither gonorrhea nor chlamydia.

3) The immune system clears gonorrhea and chlamydia without treatment -- in males, typically within a few weeks to months. After that happens, the tests are negative. This isn't a false negative result; it proves neither infection was present at the time of testing. There is no test to determine whether someone has had past infection with either of these STDs. However, spontaneous cure rarely if ever occurs as soon as 3 weeks. Your negative results are 100% proof you did not acquire either of them.

I hope these comments are helpful. Let me know if anything isn't clear.

• Based on the exposure from 3 weeks ago, oral sex only, protected felatio and cunnilingus - after reviewing our previous exchanges my impression is you would agree that perhaps the risk was low enough that it may not warrant me re-testing for HIV and Syphilis in another 3 weeks and to continue with my plan for annual screenings yearly?  Again with the understanding that I will not participate in anything else but oral sex.  

• Also very interesting and good to know on Chlamydia and Gonorreah.  I totally understand I was not infected recently by either which is of course good news, but wondering in the event I had it in the past, didn't know, and it cleared on its own (without medication), could it cause any damage to the body?  I never recall having had any symptoms ever, but am curious.  I thought I read somewhere that without medication it could cause damage down the road.

Thanks again.

When gonorrhea or chlamydia in a male has not caused obvious symptoms and is cleared by the immune system, some women will have sustained Fallopian tube damage that can lead to infertility or ectopic pregnancy. But there are no known long term health problems in males.
