Tested for anti-mag?

Yes, I was tested several times. It seems to me it is part of a standard test even for the average neurologist. After some brief research I found this

“Abstract

BACKGROUND: Detection of serum antibodies to myelin-associated glycoprotein (MAG) by Western blot (WB) is a valuable assay to diagnose a distinct type of demyelinating polyneuropathy with immunoglobulin M (IgM) monoclonal gammopathy. In this study, the diagnostic accuracy of a new and more practical ELISA to detect these antibodies was validated.”

So, you may see the test listed as ‘MAG’, ‘anti-MAG’, ‘Western Blot’, Elissa, or simply as Ig. At Mayo they listed it under Immunology AG, Immunology III. But, I have seen all these descriptions in my various lab reports.
