82225:SENSORY NEUROPATHY EVALUATION | |||||||||
Methodology: | Enzyme Immunoassay (EIA) / Capillary Zone Electrophoresis (CZE) / Immunoblot (IB) | ||||||||
Edit Date: | 5/7/2009 | ||||||||
Components: | Myelin-Associated Glycoprotein IgM Autoantibodies / SGPG IgM Autoantibodies / IFE Paraprotein / Immunofixation Electrophoresis (IFE) Interpretation / Neuronal Nuclear (HU) Autoantibodies – WB | ||||||||
Performed: | Tuesday – Friday | ||||||||
Released: | 5 days after setup at PeaceHealth Laboratories’ reference lab. | ||||||||
CPT Code: | 83520-90 x2 / 84181-90 / 86334-90 | ||||||||
Specimen Collection Details | |||||||||
Collection: | One 7.5 mL serum separator tube (SST). | ||||||||
Handling: | Centrifuge and separate serum from cells and pour into a plastic vial. | ||||||||
Stability: | 7 days ambient, 7 days refrigerated, or 2 month frozen. | ||||||||
Standard Volume: | 2.5 mL serum. | ||||||||
Minimum Volume: | 2 mL serum. | ||||||||
Transport: | Refrigerated. | ||||||||
Comments: | Low concentrations of one or more autoantibodies in this evaluation can be associated with neuropathies secondary to infectious, inflammatory or systemic autoimmune diseases. However, high concentrations of one or more autoantibodies, especially with paraproteinemia, are suggestive of a primary immune-mediated peripheral neuropathy. | ||||||||
