Clinical Info
CSF VDRL test is used an aid in diagnosis of neurosyphilis. CSF VDRL detects non-treponemal antibodies and has lower sensitivity than CSF treponemal tests such as FTA, therefore a negative CSF VDRL result cannot reliably rule out neurosyphilis (including ocular syphilis and otosyphilis). Clinical correlation is required.
