This test is used primarily to evaluate magnesium deficiency. Magnesium deficiency produces neuromuscular disorders. It may cause weakness, tremors, tetany, and convulsions. Hypomagnesemia is associated with hypocalcemia, hypokalemia, long-term hyperalimentation, intravenous therapy, diabetes mellitus, especially during treatment of ketoacidosis; alcoholism and other types of malnutrition; malabsorption; hyperparathyroidism; dialysis; pregnancy; and hyperaldosteronism. Renal loss of magnesium occurs with cis-platinum chemotherapy.
Magnesium deficiency is described with cardiac arrhythmias. The concept that magnesium deficiency may cause arrhythmias is of significant concern. Increased magnesium levels relate mostly to patients in renal failure. Marked increases may be found in such patients who take magnesium salts usually found in antacids which contain magnesium. High magnesium levels are manifested by decreased reflexes, somnolence, and heart block.
No special preparation is necessary prior to blood sample collection.
