MuSK Antibody Test

The MuSK antibody test is a diagnostic test used to detect the presence of antibodies against muscle-specific tyrosine kinase (MuSK) in the blood. This test is primarily used to aid in the diagnosis of myasthenia gravis (MG), a rare autoimmune disorder that causes muscle weakness and fatigue.

Myasthenia gravis is caused by the immune system attacking and damaging the neuromuscular junction, which is the area where nerves and muscles meet. The presence of MuSK antibodies in the blood is associated with a specific form of myasthenia gravis called MuSK antibody-positive myasthenia gravis.

The MuSK antibody test is a blood test that measures the level of MuSK antibodies in the blood. It is usually ordered when a patient shows symptoms of myasthenia gravis, such as muscle weakness, drooping eyelids, difficulty swallowing, or difficulty breathing. The test is also used to monitor the response to treatment in MuSK antibody-positive myasthenia gravis patients.

The MuSK antibody test is a highly specific test, meaning that it is very accurate in detecting the presence of MuSK antibodies in the blood. However, it is important to note that a negative test result does not completely rule out the possibility of MuSK antibody-positive myasthenia gravis, as some patients may not produce detectable levels of MuSK antibodies.

The MuSK antibody test is a relatively new test and is not available at all laboratories. It is typically performed at specialized neuromuscular disease centres or by referral from a neurologist.
