Test ID: CRMWC    
Collapsin Response-Mediator Protein-5-IgG (CRMP-5-IgG) Western Blot, Spinal Fluid

Useful For Suggests clinical disorders or settings where the test may be helpful

This testing is recommended in cases of chorea, vision loss, cranial neuropathy and myelopathy. It is recommended that PAVAL - Paraneoplastic Autoantibody Evaluation be ordered in conjunction with this test if not previously performed. Western blot analysis is indicated when interfering nonorgan-specific or coexisting neuron-specific autoantibodies in serum or spinal fluid preclude unambiguous detection of CRMP-5-IgG, by indirect immunofluorescence assay, or when the immunofluorescence assay is negative in a patient whose neurological presentation suggests a CRMP-5-IgG-related syndrome.
