Magnesium measurements are used in the diagnosis and treatment of hypomagnesemia (abnormally low) and hypermagnesemia (abnormally high). Magnesium is a major intracellular cation, second only to potassium in concentration. Little is known about the factors regulating magnesium levels in plasma. It is believed that the parathyroid gland may be involved. Magnesium ions serve as activators for a number of important enzyme systems engaged in the transfer and hydrolysis of phosphatase, prostatic acid phosphatase, and creatinine kinase. Decreased serum magnesium levels have been observed in cases of diabetes, alcoholism, diuresis, hyperthyroidism, hypoparathyroidism, malabsorption, hyperalimentation, myocardial infarction, congestive heart failure and liver cirrhosis. Increased serum magnesium levels have been found in cases of rena failure, dehydration, and severe diabetic acidosis and Addison's Disease.

Grossly hemolyzed specimens will be rejected. Transport room
