Treponema pallidum Antibodies FTA-ABS Blood Test

* This is not a home test kit. You will need to visit a local lab for testing.

The Purpose of the Treponema Pallidum Antibody Test

You probably know that syphilis is a sexually transmitted disease that requires treatment to prevent serious health issues. But did you know that syphilis is caused by a bacteria called Treponema pallidum?

That’s why, when it comes to determining if you have syphilis, there are two main types of tests to choose from. A nontreponemal test screens for antibodies, or proteins, the body’s immune system produces in response to syphilis as well as other infections. A treponemal test, such as the FTA-ABS test, looks for the specific Treponema pallidum antibodies to help confirm a syphilis infection. If you want to be proactive about your sexual health, or you are experiencing symptoms associated with syphilis, you can order this test from Personalabs with the utmost privacy and convenience.

What Does the Blood Test for FTA-ABS Measure?

This test will detect antibodies that signal a syphilis infection.

Who Should Take a Treponema Pallidum AB Test?

With syphilis, early testing is always better because swift treatment of an infection is most effective (and often simpler, requiring just a penicillin dose). It also prevents you from spreading the infection during its earliest stages. Watch for symptoms that include:

  • A small sore on the body that doesn’t hurt to touch
  • Swollen glands in the neck, armpits, or groin
  • White patches inside the mouth
  • Unusual skin growths
  • Fever, achy joints, fatigue, and other flu-like symptoms

Anyone who is sexually active with multiple partners should be tested regularly for STDs, including syphilis.

You don’t need to follow any specific instructions before taking the FTA-ABS test.

FTA-ABS Blood Test Results

negative result means you don’t have syphilis. If you get a positive result, it’s important to get treatment as soon as possible. If the infection spreads, it raises the risk of permanent damage to organs such as the brain, liver, and heart, as well blood vessels, nerves, bones, and more.
