The Serum Magnesium test measures the amount of magnesium in your blood. Magnesium is needed for your nervous, gastrointestinal, and cardiovascular systems to work normally. Your body gets magnesium from certain foods. Magnesium measurements are used in the diagnosis and treatment of hypomagnesemia (abnormally low plasma levels of magnesium) and hypermagnesemia (abnormally high plasma levels of magnesium). Magnesium is decreased in chronic nephritis, acute pancreatitis, and alcoholic cirrhosis. It is increased in acute or chronic renal failure and Addison's Disease.
A significant deviation from the normal range may require further evaluation by your physician.
