Syphilis Test VDRL
The syphilis test, VDRL is used to diagnose syphilis. The nontreponemal test is usually performed on blood but may be done on a serum sample or cerebro-spinal fluid (CSF). The test checks for an antibody that can be produced while infected with syphilis. Syphilis test VDRL is not very useful for detecting syphilis in very early or advanced stages. The test is also used to monitor patients' response to syphilis treatment. Syphilis VDRL test can result in false positive result even in the absence of infection due to recent immunization, other bacterial and viral infections and certain chronic conditions (e.g. liver disease, malignancy). Hence, a confirmatory test, the FTA-ABS test is done to check for syphilis-specific antibodies. Though no special preparation is required on the part of an individual who is to be tested, health care officials recommend abstaining from alcohol consumption 24 hours before a VDRL test.
