Measures IgG antibodies to the syphilis bacterium from a finger-prick card. They can remain after treatment, so a positive result needs follow-up testing with a clinician.

Syphilis screening starts with a non-specific antibody test (RPR) that reacts to the infection's effect on the body. It can be positive from past, treated infection, and occasionally from other conditions, so positives automatically get a second, specific test.
The RPR level also falls after treatment, which is why it is used for follow-up. Timing matters: antibodies take time to appear after exposure, so a very early test can miss a new infection.
The screening test turns positive some weeks after infection and falls after treatment, which is how follow-up is tracked. Past treated syphilis, pregnancy, some autoimmune conditions, and other infections can make the first test react, which is why positives get a second, specific test.
A past infection usually stays positive on the specific test long-term, while the RPR level falls after treatment. That is why both are reported, and why a past treated infection needs your history to read correctly.
