Paraneoplastic Reflexive Panel, CSF
Aids in the diagnosis of paraneoplastic neurologic syndromes.
This test only evaluates for the presence of high-risk paraneoplastic antibodies, independent of neurologic phenotype. Targeted phenotype-specific panels are preferred for the evaluation of autoimmune neurologic disease. Refer to the ARUP Autoimmune Neurology Panel Components tables for phenotype-specific test options.
Testing in both serum and CSF is recommended to maximize diagnostic yield; refer to Paraneoplastic Reflexive Panel (3002929) for serum testing.

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the U.S. Food and Drug Administration. This test was performed in a CLIA-certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
Purkinje Cell (PCCA) antibody and Neuronal Nuclear (ANNA) antibody IgG are screened by IFA. If the IFA screen is indeterminate, then a Neuronal Nuclear Antibodies (Hu, Ri, Yo, Tr/DNER) IgG by Immunoblot will be added. If the IFA screen is positive at 1:1 or greater, then a PCCA/ANNA antibodies titer and Neuronal Nuclear Antibodies (Hu, Ri, Yo, Tr/DNER) IgG by Immunoblot will be added. Additional charges apply.
If CV2.1 Antibody IgG Screen by IFA is positive, then CV2.1 Antibody IgG Titer by IFA will be added. Additional charges apply.
86255 x2; 84182 x2; if reflexed add 86256 and/or 84182 x4; if reflexed add 86256
