What tests can help diagnose myasthenia gravis?

To provide a diagnosis, your doctor may ask you to have several tests:

  • Edrophonium test
    If an injection of the chemical edrophonium chloride results in a sudden and temporary advancement in your muscle strength, it signifies that you may have myasthenia gravis.
  • Ice pack test
    Your doctor will firstly place a bag filled with ice on your eyelid. After several minutes, the bag will be removed and the signs of improvement of your eyelid will be analyzed.
  • Single-fiber electromyography (EMG)
    EMG measures the electrical activity between your brain and your muscle.
  • Blood test
    Blood tests of acetylcholine receptor antibody or anti-MuSK antibody can help tell whether you have myasthenia gravis.
