A "Myasthenia Gravis Profile" that includes AChR, ASMA, and MuSK refers to a blood test panel used to diagnose Myasthenia Gravis (MG) by detecting antibodies against three key proteins at the neuromuscular junction: Acetylcholine Receptor (AChR), Striated Muscle Antibodies (ASMA), and Muscle-Specific Kinase (MuSK); essentially checking for the presence of autoantibodies that could be causing muscle weakness associated with MG.
