There is no known cure for MG, but there are effective treatments that allow many to lead full
lives. Spontaneous improvement and even remission may occur without specific therapy.
Acetylcholine Receptor Antibody blood test: an abnormal result means acetylcholine receptor antibody has been detected in your blood. It confirms the diagnosis of MG.
Anti-musk antibody testing blood test: reveals the presence of acetylcholine receptor OR muscle-specific tyrosine kinase-seropositive (MuSK) antibodies.
Electromyography: repetitive nerve stimulation that shows a pattern of responses that are characteristic of those with MG.
"Tensilon" test: the drug edrophonium chloride is injected into the vein. Improvement of strength immediately after injection provides strong support for the diagnosis of MG.
Sometimes all of these tests are negative or equivocal in someone whose story and examination still seem to point to a diagnosis of MG.
