MuSK Antibody Test

The MuSK Antibody Test detects antibodies directed against muscle-specific kinase (MuSK), a protein involved in neuromuscular transmission. This test helps identify MuSK-positive myasthenia gravis (MG), particularly in patients negative for acetylcholine receptor antibodies. Detecting these autoantibodies supports diagnosis, classification, and management of autoimmune neuromuscular junction disorders.
