Clinical Significance

Calcium is the major mineral component of bone; 99% of the body’s calcium is in bone. Calcium ions play an important role in the transmission of nerve impulses and in maintaining normal muscle contraction. Abnormal concentrations of serum calcium may indicate malfunction of the parathyroid glands, bone diseases, carcinoma, malnutrition and malabsorption syndrome, vitamin D deficiency, overdose with calcium-containing antacids, and renal diseases
