CSF-VDRL test
Alternate Names : Venereal disease research laboratory slide test - CSF
Definition
The CSF-VDRL test is used to diagnose neurosyphilis. This test looks for antibodies called reagins, which are sometimes produced by the body in reaction to the syphilis-causing bacteria. See also: VDRL
Why is the Test Performed?
The CSF-VDRL test is used to diagnose syphilis in the brain or spinal cord. Brain and spinal cord involvement usually indicates late stage (tertiary) syphilis. Blood screening tests, such as VDRL and RPR, are more effective during middle stage (secondary) syphilis.
How is the Test Performed?
The test is performed on a CSF sample obtained by lumbar puncture (spinal tap).
How to Prepare for the Test?
Before the procedure, you will be asked to review the risks and sign a consent form.
How will the Test Feel?
Usually, discomfort associated with the lumbar puncture is mild to moderate. The entire procedure usually takes about 30 minutes but may take longer. The actual fluid collection only takes a few minutes.
