Anti MAG (Myelin associated Glycoprotein) Ab

Description

The Anti-MAG (Myelin Associated Glycoprotein) Antibody test detects antibodies targeting the myelin-associated glycoprotein, a crucial component of the myelin sheath in peripheral nerves. This test is particularly important in diagnosing certain types of peripheral neuropathies, especially those associated with IgM paraproteinemia. Positive results can indicate an autoimmune cause for nerve damage, often seen in conditions like MGUS (Monoclonal Gammopathy of Undetermined Significance) associated neuropathy. The presence of these antibodies helps differentiate this specific form of neuropathy from other causes, guiding treatment decisions that may include immunomodulatory therapies. Regular monitoring of anti-MAG antibody levels can also help assess disease progression and treatment effectiveness.
