| Additional information | The VDRL test is the only serological assay which is approved for use in CSF. In patients suspected of neurosyphilis but with a non-reactive VDRL result, the FTA-ABS test may be useful in some cases. The FTA-ABS test has high sensitivity but is nonspecific with a high rate of false positive results in CSF. References: Birnbaum NR, Goldschmidt RH and Buffett WO. 1999.
