When is a syphilisis test conclusive?

[cowboysfan1976]

Here is the history of my sysphlis test results after an exposure with an Asian women where I don't remember if I wore protection or not. Exposure was on March 20. It was anal and oral sex.
1 month after exposure: April 20: Nonreactive= Main RPR Qualtive.
3 months after exposure: July 10: Nonreactive = Main RPR Qualitive.
5 months after exposure: Septhember 1st: Nonreactive = RPR.
Is this enough testing?
When is a syphlisis test considered conclusive?
What does a qualitive mean in a rpr test?
And my last question is I've had 2 marks on my upper lip that look like a blister/Sore in one month. Can this be related to late syphlisis? Is it possible that my RPR test that catch it?
Please help me, I really need it. P.S one of the marks on my upper lip was one week before my September 1st test and then reappeared one week later.

That would have happened much sooner

Thank Vance I still don't know where this outbreak on my back is related too that's why I assumed it may of been late syphlisis.

Test is conclusive after 6 weeks, you don't have syphilis.
