Clinical Significance
The serum VDRL test is an aid in the diagnosis of syphilis. The predictive value of a reactive VDRL is increased when combined with a treponemal-specific test such as FTA or TP-PA. A reactive VDRL test on CSF, free of blood or other contaminants, usually suggests past or present syphilis infection of the central nervous system.
