What it measures
- RPR
- Treponemal antibodies
Who it’s for
- A new sexual partner, or a partner with syphilis
- A painless sore or an unexplained rash
- A routine sexual health check
- Planning a pregnancy
Easy to miss
The first sign is often a small, painless sore where the infection entered, which heals by itself within a few weeks. Weeks later a rash, often on the palms or soles, or flu-like symptoms may appear, then fade too. Without treatment, syphilis can cause serious problems years later, and it can pass to a baby in pregnancy.
How the two tests work together
The treponemal antibody test shows whether you’ve ever had syphilis, and usually stays positive for life even after treatment. RPR shows whether the infection is active and is used to check that treatment has worked.
How to prepare
- Drink a couple of glasses of water beforehand: it makes the sample quicker and easier to take.
- No fasting needed. Eat and drink as normal.

Questions
When should I test after possible exposure?
Antibodies can take up to 12 weeks to appear. You can test sooner, but repeat the test at 12 weeks if the result is negative.
I’ve had syphilis before. Is this test useful?
Yes. Your treponemal antibody will stay positive, but RPR shows whether there’s a new or active infection.
