What's this test for?

This test is ideal if you're experiencing symptoms of syphilis, such as sores, rashes, or unexplained flu-like symptoms, or if you've had a positive screening test and need to confirm the diagnosis. It's also a good option if you've had unprotected sex or a new partner and want to rule out a treponemal infection. Many people use this test simply for peace of mind after a possible exposure.

What's included in this test?

This test looks for antibodies your body makes in response to the bacteria that causes syphilis. Because it's a treponemal test, it stays positive long after an infection clears, which makes it useful for confirming past or present exposure but not for checking if treatment worked.

What happens after I get my results?

Your results will show up in your account, along with an explanation of what a reactive or non-reactive result means. If your result is reactive, the report will walk you through what that means and suggest next steps, since this test stays positive for years and isn't used to track treatment progress. You can download a standard lab report from your account at any time, and if you test again in the future, the trends feature lets you keep a record of your results over time.

When will I get my results?
Results are typically ready within about 7 days of your sample being collected. You'll get a notification once your report is available in your account, so there's no need to check back constantly. If you need results sooner for a specific reason, some locations may offer faster turnaround for an added cost.
Who should consider this test?
This test is a good fit for anyone who has had a positive result on an initial syphilis screening test and needs confirmation, or anyone with symptoms like sores or rashes that could point to a treponemal infection. It's also worth considering if you've had unprotected sex, multiple partners, or a partner who tested positive. Regular testing is smart for anyone who is sexually active with new or multiple partners.
What symptoms indicate I may need this test?
Watch for painless sores (called chancres) on the genitals, mouth, or anus, unexplained skin rashes (especially on the palms or soles), swollen lymph nodes, or flu-like symptoms such as fever and fatigue. These symptoms can come and go, so don't assume they're gone for good just because they clear up. If you notice any of these signs, especially after a new sexual encounter, it's worth getting checked.
What is a treponemal antibody test and why does it matter?
A treponemal antibody test looks for your immune system's specific response to the bacteria that causes syphilis. It matters because it can confirm an infection with high accuracy, even years after the initial exposure, which helps clear up uncertainty from other screening tests. Knowing your status lets you get appropriate care and avoid passing the infection to partners.
What does a reactive (positive) result mean?
A reactive result means your body has been exposed to the bacteria that causes syphilis (or a closely related infection) at some point, even if that was years ago. This doesn't tell you whether the infection is active now or already treated, since this antibody sticks around for life. If you get a reactive result, timely treatment and follow-up testing for other infections are smart next steps.
What does a non-reactive (negative) result mean?
A non-reactive result generally means no antibodies to the syphilis-causing bacteria were found, suggesting no current or past infection. However, if you were exposed very recently (within the last 4-6 weeks), it can take time for antibodies to build up, so a repeat test may be needed if you had a recent exposure. If you have symptoms despite a negative result, don't ignore them.
How often should I retest?
If you're sexually active with new or multiple partners, testing every 3-6 months is a reasonable routine. If you've had a specific exposure or a partner tested positive, it's best to test right away and again after 6 weeks to catch infections that were too early to detect the first time. Once you've had a reactive result, retesting with this specific test isn't useful for tracking treatment, since it stays positive long-term.

What this means

A non-reactive result means no antibodies to the syphilis-causing bacteria were detected in your sample. This suggests you don't have a current or past syphilis infection, though very recent exposures (within 4-6 weeks) may not yet show up.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
