What Are the Blood Tests of Myasthenia Gravis?

Q:
What are the blood tests of myasthenia gravis?

A:
There are 15% of the myasthenia gravis patients who have tested negative for the acetylcholine antibody, which means these patients have seronegative myasthenia gravis.

Then a blood test of anti-MuSK antibody is needed. About 40% of the patients with seronegative myasthenia gravis have positive results for the anti-MuSK antibody test.

Another blood test focuses on acetylcholine receptor antibody because 85% of the myasthenia gravis patients have this antibody.

If the antibody is detected with an elevated concentration, the test can be strongly indicative of myasthenia gravis.

Key words: blood test myasthenia gravis; myasthenia gravis blood test.
