Need help with an explanation on IgG testing.

I asked my doctor yesterday. We spoke on the phone and from the research I've done, they've started to use IgG as a part of RPR because RPR isn't as accurate, but it is less expensive. She said after this much time I would definitely know because there would be something there to have set my worry on fire, so to speak. Thanks for your answer!

usually syphilis is not listed as an igg test. just double check your testing to be sure what you were actually tested for.  Mostly syphilis testing is listed as a rpr test.

As long as you specifically tested for syphilis...yes.

Sorry if I'm upsetting or frustrating you. I was tested over a year and a half after I would've contracted it. So that's more than 6 weeks. Are you saying that's conclusive?

Lets make this simple. Testing for syphilis 6 weeks after possible exposure is conclusive. Only way to know if you have syphilis is to have a specific syphilis test.

My theory is that by now it would be known as chronic and/or long term. And IgG antibodies pick up on chronic and long term infections. So wouldn't it have caught AN infection, and then continued testing to specify if it is in fact syphilis or something else?

So even though even if I would've gotten syphilis was about 2 years ago and I tested negative for IgG antibodies, it doesn't mean anything at all???

IgG is used for testing for STD's but when used it is specific for herpes or whatever. It is not just a test that covers a wide spread of STD's.

I've read that IgG can be used for: herpes testing (and differentiation between 1 and 2), syphilis, and general long term infections in the body. I wanted to know that if you HAVE tested negative for IgG antibodies, if it has to be specified during lab testing. That it is being tested against one of the aforementioned ailments or if after a period of time it simply means your body is without abnormal infection.
