FAQ

This test is recommended if you’re sexually active and have symptoms or have had unprotected sex.

In 2023, over 209,000 cases of syphilis were reported in the United States, the highest number since 1950.¹ Syphilis spreads by direct contact with a syphilis sore during vaginal, anal, or oral sex. Even if you don’t see any sores, it can still be spread.
Syphilis symptoms can be hard to notice and may come and go over time. The best way to know if you have syphilis is to get tested. You may not notice symptoms, or you may mistake them for another skin condition such as a pimple or rash. Syphilis occurs in stages:

Primary Stage: A syphilis sore shows up where the infection entered your body. This is usually on or around your vagina, penis, scrotum, or anus. In rare situations syphilis can appear on your lips or mouth. These sores are very contagious and show up between 3 weeks and 3 months after infection. These sores usually last 3 to 6 weeks and then go away on their own.

Secondary Stage: Symptoms include rashes on the palms of your hands, soles of your feet or other parts of your body. This rash may be hard to see, and it usually doesn't itch. You may have flu-like symptoms. This can last 2 to 6 weeks at a time and may come and go for up to 2 years. These symptoms will go away by themselves, but until you get treated for syphilis, you'll still have the infection, and it can move into the dangerous later stages.

Late Stage: In between the secondary stage and the late stage, there may be times when your syphilis infection is latent (there are no signs or symptoms at all) for months or even years - but you still need treatment to get rid of it. People who have had syphilis for a long time face serious health problems. Late stages of syphilis can cause tumors, blindness, and paralysis. It can damage your nervous system, brain and other organs.

Syphilis can be cured with antibiotics in the early stages. If you get treatment late, it will still cure the infection and stop future damage to your body. But the damage that late-stage syphilis has already caused can't be changed or healed. Complications from late-stage syphilis can occur 10-20 years after you first get infected.
You might have some concerns about your sexual health and what your test result will be. This is normal. By deciding to learn about your syphilis status, you have taken a giant step toward taking control of your future and protecting your health.

It can take time after infection for the test to be able to detect syphilis in your body. This time period can vary from person to person. This time period is commonly referred to as the "window period".

As with many tests, there is a possibility of a false negative result. It can take 10 to 90 days after being exposed to syphilis for the test to be able to reliably detect the infection. If your test result is negative, but you still think you may be positive:

Retake the test after symptoms appear OR
Retake the test within 90 days after the potential exposure. Try to avoid sexual contact during this time

This will help reduce the possibility of a false negative result.
If your test is positive, contact your healthcare provider to discuss your First To Know® Syphilis Test result and whether treatment or further testing is needed.

Syphilis can be cured with the right antibiotics. However, treatment will not undo any damage that the infection has already caused.

After you have received appropriate treatment, syphilis will not recur on its own. However, you can become re-infected if you have sexual contact with someone who has syphilis.
Risk of syphilis results from unprotected sexual contact with one or multiple partners who is/are currently infected with syphilis. It is possible for a person to be infected with syphilis without having symptoms (i.e., asymptomatic) and still transmit the infection to another. If you are sexually active, doing the following can lower your chances of getting syphilis:

Being in a long-term, mutually monogamous relationship with a partner who has been tested and has negative STI test results
Using latex condoms the right way every time you have sex
Asking your partner if he or she has ever had an STI. It may be awkward, but it's important to have an honest discussion with your partner. People with a history of STIs have a higher risk of infection
Learning that you may have syphilis can be stressful. Remember that you are not alone! Many people and organizations in communities around the world are ready, willing and able to help you. The key is to ask for help as soon as possible.
