STD/HIV test window accuracy

[Bobvano]

Hello,

Im a 26 year old male from the Netherlands and i have a couple of questions.
(my apologies for some spelling errors, English is not my native language)

A while ago i had unprotected sex with another male.
After this encounter i had a full STD/HIV test done at exactly 90 days post exposure (Blood test,urine test,throat swab,anal swab,Hepatitis B was not tested because of vaccination).

All the test results where negative.

But after this i (stupid i know) started looking on the internet and read a few things,i read that when you have HIV your Syphilis test window mat become longer?
I also read something about when your infected with the Syphilisbacteria the HIV testing window might become longer (because the body is busy first trying to fight of Syphilis and as a result produces HIV antibodies later).

So i started to worry if any of this is true and if my 90 days test isnt enough to rule out Syphilis and HIV anymore.
Because i now have the (unlogical) thought in my mind that maybe i was infected with HIV and Syphilis simultaneously and that coinfection results in 1 of the 2 tests (or both) not being definitive.

I also read somewhere that a Syphilis chancre may contain HIV (if the person has HIV ofcourse) and if then you get infected with Syphilis,HIV may travel along (inside) the Syphilisbacteria to infect you?

So my specific questions are:

1) Can HIV or Syphilis delay eachothers testingwindow?

2) Is my negative test 90 days post exposure still enough to rule out all STD's/HIV?

3) Is it true that HIV can/may travel along inside the Syphilisbacteria?

4) do the vaccine shots for Hepatitis B have any affect on Syphilis or HIV testing? (my last vaccine shot was performed not so long before the testing day).


*Extra information : The Syphilis test performed was the TPHA/TPPA test (standard Syphilis screeningtest in The Netherlands), the HIV test i do not know but i pressume it was a late generation antibody test


It would really help for my peace of mind if someone could awnser these quistions.

Bob.

You know what might be good to do if you have some extra funds. Go see your doctor and explain your concerns or go to the expert site here and ask a doctor. I believe there is a slight charge but would be best to get a doctor to answer you at this point since your thinking of possible exposure and googled some issues. Just my thoughts.

I dont know if he was a CSW but it was a guy i didnt know at all so god knows how mutch unprotected sex he has.

Im also anxious because i have a new girlfriend (im Bi) since a few weeks and i want to know if its safe and responsible to have unprotected sex with her (she has been tested and is clean).

Hi and welcome, test period as below
Syph   6 weeks
HIV 3 months
If you tested negative your ok. Even through unprotected sex is a higher risk than protected, i cant believe the person you were with had all of them unless they were a professional sex worker that never used condoms.
It sounds like your really anxious about this. Just relax and be thankful your tests came back negative and go on with you life using this as a lesson to use a condom next time.
