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.
The FTA test is not recommended for cerebrospinal fluid specimens. For CSF specimens, Treponema pallidum (VDRL), Cerebrospinal Fluid with Reflex to Titer (0050206) test is recommended.
See Compliance Statement B: www.aruplab.com/CS
Inconclusive final reports indicate the initial specimen submitted has been tested twice and cannot be interpreted as either reactive or nonreactive. If it is the second specimen submitted on a patient and the report is again inconclusive, it is impossible to state definitively that the patient does or does not have syphilitic infection.
