Diagnosing myasthenia gravis (MG) involves several steps to confirm the presence of the condition. Here are the common diagnostic methods: 1. Clinical Examination A healthcare provider will review your symptoms and medical history, and conduct a physical examination to assess muscle strength and fatigue. 2. Blood Tests Antibody Tests: Blood tests can detect antibodies against acetylcholine receptors (AChR) or muscle-specific kinase (MuSK), which are often present in Myasthenia Gravis. 3. Electromyography (EMG) Repetitive Nerve Stimulation: This test measures the electrical response of muscles to repeated nerve stimulation. Single Fiber EMG: This is a more sensitive test that can detect impaired nerve-to-muscle transmission. 4. Imaging Tests CT Scan or MRI: These imaging tests can check for the presence of a thymoma (a tumor in the thymus gland), which is sometimes associated with Myasthenia Gravis. 5.Neostigmine Test Neotigmine Test: This involves injecting a drug called edrophonium chloride (Tensilon) to see if it temporarily improves muscle strength, which can indicate Myasthenia Gravis. 6. Pulmonary Function Tests Respiratory Muscle Strength: These tests measure how well the lungs are functioning and can help assess the impact of MG on breathing muscles
