How is fasciculation diagnosed?

The cause of muscular fasciculation is diagnosed in several different ways depending on what the physician can rule out. Blood tests can be used to check for irregularities in the body's electrolyte levels or thyroid problems. Someone may also be given a physical exam to test muscle strength and nerve control, which may involve an electromyography (EMG) test. In the most severe cases, tests can be done through magnetic resonance imaging (MRI) of the brain or spinal cord to check for neurological disorders.
