what test is for electrolyte
Electrolyte tests are performed from routine blood tests. The techniques are simple, automated, and fairly uniform throughout the United States. During the preparation of blood plasma or serum, health workers must take care not to break the red blood cells, especially when testing for serum potassium.
Electromyography (EMG) is a form of electrodiagnostic testing that is used to study nerve and muscle function. Commonly performed by a physiatrist or neurologist trained in this procedure, EMG testing can provide your doctor with specific information about the extent of nerve and/or muscle injury and can also determine the exact location of injury and give some indication whether the damage is reversible.
