Additional Codes
CPOE: Ref Sensory Neuropathy Antibody Panel with Reflex to Titer and Neuronal Immunoblot
DOE: Ref Sen Neur
Specimen
Gold SST tube, collect 4.0 mL blood
Centrifuge within 2 hours of specimen collection
Serum, 2.0 mL (1.0 mL minimum), refrigerated
Rejection Criteria
Plasma, other body fluids, contaminated specimens, heat-inactivated specimens, hemolyzed specimens, grossly icteric specimens, lipemic specimens, specimens not centrifuged < 2 hours from collection, specimens at room temperature >24 hours, insufficient quantity, unlabelled specimens
Interpretative Information
Aid in diagnosis of a sensory neuropathy when malignancy, other than plasma cell dyscrasia, is suspected.
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, and Tr/DNER) IgG by Immunoblot will be added. If the IFA screen is positive at 1:10 or greater, then a PCCA/ANNA antibodies titer and Neuronal Nuclear Antibodies (Hu, Ri, Yo, and Tr/DNER) IgG by Immunoblot will be added. Additional charges apply.
