Why the Test is Performed The CSF-VDRL test is done to diagnose syphilis in the brain or spinal cord. Brain and spinal cord involvement is often a sign of late-stage syphilis.Blood screening tests (VDRL and RPR) are better at detecting middle-stage (secondary or latent) syphilis.VDRLThe VDRL test is a screening test for syphilis.

This means you can have syphilis even if this test is normal. Therefore, a negative test does not always rule out the infection. Other signs and tests may be used to diagnose neurosyphilis. What Abnormal Results Mean A positive result is abnormal and is a sign of neurosyphilis. Risks Risks for this test are those related to lumbar puncture, which may include:Bleeding into the spinal canal or around the brain (subdural hematomas). Discomfort during the test. Headache after the test that can last a few hours or days. If headaches last more than a few days (especially when you sit, stand or walk) you might have a CSF-leak. You should talk to your physician if this occurs. Hypersensitivity (allergic) reaction to the anesthetic. Infection introduced by the needle going through the skin.Your provider can tell you about any other risks.Open ReferencesReferencesKarcher DS, McPherson RA.
