Why is the Test Performed?
This test is performed when an abnormal blood level of magnesium is suspected.
About half of the body's magnesium is found in bone, where it plays a structural role (along with calcium, phosphate, and various proteins). In all other tissues magnesium is among the most abundant of all the intracellular (inside the cell) electrolytes, second only to potassium.
Magnesium is necessary for essentially all biochemical processes. For example, synthesis and use of ATP (the major source of energy for all cells).
