This test detects antibodies that develop in response to Treponema pallidum, the bacteria that causes syphilis. This is the most accurate test for this bacterium. Early detection and treatment of syphilis is the best way to protect against serious complications.
Test results may take 3 to 4 business days once the specimen is received by the laboratory. When the result is positive, additional tests including a rapid plasma reagin (RPR) are used to confirm infection with syphilis.
