Calcium

Calcium is an essential mineral primarily stored in bones and teeth. It ensures the stability of the skeleton and plays an important role in muscle function, blood clotting, and nerve signal transmission. A blood test measures the proportion circulating in the blood.

Too low calcium levels can cause muscle cramps, tingling, or heart rhythm disturbances. Too high levels often indicate disorders of the parathyroid gland, certain tumors, or excessive intake of vitamin D.
