Myelin Associated Glycoprotein (MAG) Antibody, IgM
Also known as: MAGM ELISA
Use
This test is used to identify elevated IgM antibody concentration against myelin-associated glycoprotein (MAG), which suggests active demyelination in peripheral neuropathy. It is a stand-alone test for autoimmune neuropathies and should be used alongside other clinical parameters for disease confirmation.
Special Instructions
Not provided.
Limitations
The test alone is not diagnostic and should be used in conjunction with other clinical parameters for a comprehensive assessment. The presence of MAG antibodies is indicative but not definitive for specific neuropathies, and results should be interpreted in a broader clinical context.
