🧪 Syphilis (FTA-ABS) Testing — Confirmatory Syphilis Testing with Desert Mobile Medical

The FTA-ABS (Fluorescent Treponemal Antibody Absorption) test is a confirmatory blood test used to detect antibodies specific to Treponema pallidum, the bacterium that causes syphilis. It is often performed after an initial screening test like the RPR (Rapid Plasma Reagin) comes back positive.

🔍 What Does FTA-ABS Detect?

Unlike the RPR, which looks for antibodies the body makes in response to cellular damage from infection, the FTA-ABS detects treponemal antibodies that specifically target the syphilis bacterium. These antibodies typically remain in your body for life, so this test can confirm past or present infection, even if symptoms are not currently present.

🧬 When Is It Used?

• To confirm a syphilis diagnosis after a positive RPR test

• In cases of late or latent syphilis when symptoms may not be obvious

• When non-treponemal tests are inconclusive

• As part of a comprehensive STD evaluation
