For CSF specimens, Treponema pallidum (VDRL), Cerebrospinal Fluid with Reflex to Titer is preferred. May aid in the workup of neurosyphilis.
Semi-Quantitative Indirect Fluorescent Antibody
Transfer 1 mL CSF to an ARUP Standard Transport Tube. (Min: 0.2 mL)
Serum. Contaminated, heat-inactivated, or hemolyzed specimens.
Ambient: 48 hours; Refrigerated: 5 days; Frozen: 1 year
The significance of a reactive result in the FTA-ABS CSF test is unknown. The CSF from persons treated in the secondary or latent stage of syphilis and without signs of neurosyphilis may be reactive. A nonreactive result in the FTA-ABS CSF test suggests the absence of neurosyphilis.
Treponema pallidum (VDRL), Cerebrospinal Fluid with Reflex to Titer (0050206) is the recommended test for CSF specimens. If suspicion of neurosyphilis remains after VDRL testing, testing of the CSF with FTA-ABS may be considered.
