Test Overview
NSCSF: ELISA
NSSER: Tech interpretation
VDSFT: Flocculation/Agglutination
This test should only be ordered in patients who are seropositive for syphilis in blood. Testing begins with syphilis IgG screening of the spinal fluid (CSF) specimen. If the screen is negative, no additional testing will be performed. If the CSF screen is reactive, the paired CSF and serum specimens will be used to establish the antibody index.
Samples that result as Syphilis Antibody Index negative do not undergo additional testing.
Samples that result as Syphilis Antibody Index positive or equivocal will be reflexed for VDRL testing to establish a semi-quantitative titer.
Negative
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
