The asymptomatic patient with a positive VDRL test.

Although VDRL and RPR tests are excellent screens for syphilis, false-positive reactions do occur. A positive VDRL or RPR test must be confirmed with an FTA-ABS test. Patients with positive serologic tests should have a thorough physical examination to determine the stage of syphilis. A patient with a low-titer VDRL or RPR may have active disease and may require lumbar puncture to rule out neurosyphilis.
