what are normal serum calcium levels
CALCIUM. Calcium is important for many bodily functions. The normal concentration of total serum calcium (bound calcium plus free calcium) is in the range of 8.8-10.4 mg/dL. About 40% of the total calcium in the plasma is loosely bound to proteins; this calcium is referred to as bound calcium. The normal range of free calcium is 4.8-5.2 mg/dL.
