Calcium

Also Known As: Total Calcium, Ionized Calcium

Calcium is the most abundant and one of the most important minerals in the body. It is essential for cell signaling and the proper functioning of muscles, nerves, and the heart. Calcium is needed for blood clotting and is crucial for the formation, density, and maintenance of bones and teeth. A calcium test measures the amount of calcium in the blood or urine, which reflects the amount of total and ionized calcium in the body.
