Autoimmune Axonal Neuropathy Profile, Spinal Fluid
Also known as: Autoimmune Axonal Neuropathy Panel Spinal Fluid, Paraneoplastic
Use
This test should be considered for the differential evaluation of patients who present with a subacute neurological disorder of undetermined etiology, especially when nerve conduction velocity studies reveal lower amplitudes with a relatively preserved conduction velocity.
Special Instructions
If a reflex test is performed, additional charges/CPT code(s) may apply. For adults and patients with suspicion of cancer, additional evaluation of paraneoplastic autoantibodies is recommended (see Test No. 505500).
Limitations
This test was developed and its performance characteristics determined by Labcorp in accordance with CLIA requirements. It has not been cleared or approved by the Food and Drug Administration.
