RPR Syphillis Test 1:1

Hello Dr.,

I recently had an STD panel done. My RPR came back reactive and the RPR Quant was 1:1. I am still waiting for the third test on the report that is related to syphillis.

There is some unprotected oral i have experienced in the last 6 months and I recently (4 weeks) had unprotected sex with a two different females.

Please help, I'm very confused.

This is likely a false positive, unless you've had syphilis in the past. If that's the case, some people always test positive with a 1:1 or a 1:2.

Do you have any symptoms - any sores? If you don't, then it's probably a false positive.

I've never been treated for or tested positive for Syphilis. I have not noticed any sores - like a chancre.

3 months ago I experienced a skin rash on my armpit(s) area and upper thigh(s) that a dermatologist saw as nothing major. I used a antiseptic soap for a few weeks and it resolved itself.
The rash doesn't sound like a syphilis rash, and if you were in secondary syphilis, your titers would be much higher than a 1:1.

When are you supposed to get your other test back?
I should get results back tomorrow for the last line item, right now my results read:

012005 RPR, Rfx Qn RPR/Confirm TP.   RPR Abnormal      Reactive      Non Reactive 01

012021 RPR Qn+TP Abs RPR, Quant.      Above High Normal 1:1           NonRea<1:1 01

Treponema pallidum Antibodies       WILL FOLLOW      01
Treponema pallidum Antibodies - this test is also known as the TPPA, and this is what is going to help.

I noticed you posted on the other false positive thread, and that person had traveled extensively, so he could have had another condition that causes his chronic false positives. You've only had one, which may be a fluke. That does happen.

Here's some info on that, though -


Don't get too ahead of yourself here. You've had one test. It might just be a fluke.
Test results came back on TPPA as non reactive and normal - which seems good - what do I make of this?

Should I get retested immediately? Thank you for all your feedback. It is so appreciated.
That is good, and it means you don't have it.

I see no reason to retest unless the females you were a month ago with are particularly high risk. Syphilis is uncommon in most developed countries.

I wouldn't think of this as anything other than a fluke, and wouldn't give it another thought.
That is fantastic to read, thank you, I was really nervous and confused. Reading that false positives can be attributed to other things going on, would you recommend I go to the dr and get full blood work done generally?
Not from one test with a 1:1. I'd consider it a test fluke and move on. If you are otherwise healthy, I wouldn't worry about it at all.
