Building Strong Bones
Calcium and phosphorous are the most abundant minerals found in the body, and the majority of both minerals are found in the skeletal system. Calcium regulation is required for many basic body functions, such as cell function, bone structure, blood clotting, and neural transmission. Insufficient calcium or loss of calcium is called hypocalcemia, whereas too much calcium in the blood, often a result of malignancy or primary hyperthyroidism, is called hypercalcemia. The body regulates calcium through the parathyroid hormone (PTH) and vitamin D, and, to a lesser extent, calcitonin.

Clinical Utility of Calcium and PTH for Differential Diagnosis
Physicians use the combination of calcium and PTH measurements to aid in the differential diagnosis of several diseases.
