Syphilis testing usually follows a two-step process. First, a “screening” test (like RPR or VDRL) is done. If that is positive, the FTA-ABS is used to verify the result. It uses a specialized fluorescent microscope to “light up” the bacteria if the specific antibodies are present in your blood. The “Absorption” part of the test ensures that other common, non-syphilis bacteria don’t cause a false positive.
