What's this test for?

This test is ideal if you're concerned about potential syphilis exposure or experiencing unexplained symptoms like unusual sores, rashes, or flu-like symptoms. It helps detect syphilis infection by identifying antibodies to Treponema pallidum bacteria, giving you clear answers about your sexual health status. Many people use this test for peace of mind after unprotected sexual contact or as part of routine STI screening.

How should I prepare for this test?

No special preparation is needed for this test. You can eat and drink normally before your blood draw. Keep in mind that if confirmation testing is required based on initial results, the turnaround time may be extended beyond the standard timeframe. Simply visit your chosen lab location during their operating hours.

What's included in this test?

T. Pallidum Ab

This test measures antibodies to Treponema pallidum, the bacteria that causes syphilis. It uses a cascading reflex approach, meaning if initial screening is positive, the lab automatically performs additional confirmatory tests to ensure accurate results. This comprehensive approach helps distinguish between active infection, past treated infection, and false positives, providing you with the most reliable diagnosis possible.

What happens after I get my results?
You'll receive doctor notes in simple language explaining what your syphilis antibody test results mean for your health. These notes include specific next steps, such as whether treatment is needed, when to follow up with a healthcare provider, or if additional confirmatory testing is recommended. You'll also get the standard lab report and can track your results over time using our trends feature to monitor your sexual health.
When will I get my results?
Your results are typically available within 7 business days after your blood sample is collected. However, if your initial screening requires additional confirmatory testing through the cascading reflex process, the turnaround time may be extended to ensure the most accurate diagnosis. You'll be notified as soon as your complete results are ready.
Who should consider getting this test?
This test is important for anyone who has had unprotected sex with a new or multiple partners, has a partner diagnosed with syphilis, or is experiencing symptoms like painless sores, skin rashes, or swollen lymph nodes. It's also recommended for pregnant women as part of prenatal screening, individuals with other STIs, and anyone wanting routine sexual health screening.
What symptoms indicate I may need this test?
Early syphilis may cause painless sores or ulcers on the genitals, mouth, or rectum that appear 10-90 days after exposure. Secondary symptoms can include skin rashes on palms and feet, flu-like symptoms, swollen lymph nodes, hair loss, or white patches in the mouth. Many people have no noticeable symptoms in early stages, which is why testing after potential exposure is important even if you feel fine.
How can I protect myself from syphilis?
Consistent and correct use of condoms during vaginal, anal, and oral sex significantly reduces your risk of syphilis transmission. Limiting your number of sexual partners, having open conversations about STI testing with partners, and getting tested regularly if sexually active all help protect your health. Avoiding sex when you or your partner has visible sores or symptoms is also important.
What is syphilis and why does it matter?
Syphilis is a bacterial infection transmitted through sexual contact that progresses through stages if left untreated. In early stages, it's highly curable with antibiotics, but untreated syphilis can lead to serious complications affecting the heart, brain, and other organs years later. Early detection and treatment are crucial to prevent long-term health problems and stop transmission to others.
How often should I get tested for syphilis?
If you're sexually active with multiple partners or have a partner whose STI status is unknown, consider testing every 3-6 months. After treatment for syphilis, your doctor will recommend follow-up testing at specific intervals to ensure the infection is cleared. If you're in a mutually monogamous relationship and both partners have tested negative, annual screening or testing when circumstances change is typically sufficient.
