VDRL, Serum
Clinical Use
Order TestUse
The serum VDRL test serves as an aid in the diagnosis of syphilis. The predictive value of a reactive VDRL result is enhanced when used in conjunction with a treponemal‑specific test such as FTA or TP‑PA. In cerebrospinal fluid (CSF), a reactive VDRL—when not contaminated by blood or other substances—typically indicates current or past neurosyphilis.
