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.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
