What's this test for?

This test is ideal if you're following up on a positive syphilis screening result and need confirmation before drawing any conclusions. It helps if you have already had a non-treponemal test (like an RPR) come back positive and want to know whether it truly reflects a syphilis infection or a false alarm. It's a confirmation step, not a first-line screening test on its own.

What happens after I get my results?

Your results will show up in your account along with a plain-language explanation of what a positive or negative reading means. If your result confirms syphilis antibodies, the next step is prompt treatment and retesting after treatment to confirm the infection has cleared. If results are negative, it likely means your earlier positive screening was a false positive, though your results report explains any situations where retesting is recommended. You can download the full lab report anytime and track any future related tests over time using the trends feature.

Who should consider this test?

Anyone who has already received a positive result on a non-treponemal syphilis screening test (such as RPR or VDRL) should consider this confirmatory test. It's also useful for people who want a more specific check after an ambiguous or borderline screening result. This test is not meant to be the first test you take if you've never been screened for syphilis before.

What symptoms indicate I may need this test?

You may need this test if you've noticed sores, rashes, or unusual skin changes after a possible exposure, especially if you've already had a positive initial syphilis screen. Other reasons include a partner testing positive for syphilis or a routine screening coming back positive during pregnancy or a regular checkup. Because early syphilis symptoms can be mild or go unnoticed, many people only find out after a screening test flags a concern.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification as soon as your results are posted to your secure online account. If you need results sooner for treatment planning, check your order confirmation for any expedited options.

What is syphilis and why does confirmatory testing matter?

Syphilis is a bacterial infection spread through sexual contact that can cause serious health problems if left untreated. Because the initial screening test (non-treponemal) can sometimes give false positives from unrelated conditions, this antibody test specifically checks for antibodies made in response to the actual syphilis bacteria. Confirming the diagnosis this way helps avoid unnecessary treatment for a false alarm, or ensures you get treated promptly if the infection is real.

What does a positive result mean?

A positive result means your body has antibodies against the syphilis bacteria, which usually confirms a current or past infection. This antibody typically stays detectable for life, even after successful treatment, so a positive result along with symptoms or a recent exposure usually means treatment is needed now. Prompt treatment is important to prevent the infection from progressing and to avoid spreading it to others.

What does a negative result mean?

A negative result means no syphilis antibodies were found, which usually means your earlier positive screening test was a false positive. False positives can happen due to other infections, autoimmune conditions, or even pregnancy. If you still have symptoms or ongoing concerns, retesting after a few weeks can help rule out an infection caught too early to detect.

How often should I retest?

If your results confirm syphilis and you complete treatment, retesting every few months (commonly at 6 and 12 months) is recommended to confirm the treatment worked. If you're sexually active with new or multiple partners, annual screening is a reasonable habit regardless of past results. Your results report will note if your specific case suggests a different retest timeline.

What should I do if my results are abnormal?

If your result confirms syphilis antibodies, treatment with antibiotics is the standard next step and should happen as soon as possible. Avoid sexual contact until treatment is complete and you've been told it's safe to resume. Let recent sexual partners know so they can get tested too, since syphilis can spread even when symptoms aren't obvious.
