Myasthenia Gravis (suspected or established diagnosis)

NOTE: This pathway is intended for use in patients where there is a high clinical suspicion for a new diagnosis of myasthenia gravis based on signs and symptoms OR for patients with an established diagnosis of myasthenia gravis and concern for disease worsening. Myasthenia gravis is a chronic autoimmune neuromuscular disorder with a bimodal age distribution classified as early onset (age 20s-30s, women > men and late-onset (age 60s-80s men > female). Symptoms may seem relatively non-specific. A history of fatiguing/fluctuating weakness involving preferentially affected muscle groups adds to diagnostic certainty.
