Blood Test
Blood tests are commonplace for healthcare providers trying to determine specific types of gMG. Acetylcholine receptor (AChR) antibodies play a role in muscle movement. With 80-85% of people undergoing a diagnosis for MG testing positive for the AChR antibodies, a blood test can effectively help a healthcare provider to confirm a person has MG. Where a positive test will support the diagnosis for MG, for a negative test - something known as an Anti-MuSK (muscle-specific kinase) antibody test may be necessary. Around 6% of people who test negative for the AChR antibody test can test positive for Anti-MuSK antibodies.
