What is the normal range for serum calcium levels?

The normal range for serum calcium levels is indeed 8.5 to 10.2 mg/dL. This range is critical for maintaining several physiological functions, including bone health, muscle contraction, nerve transmission, and blood clotting. Adequate calcium levels are essential for cellular processes and signaling. Values below or above this range can indicate various medical conditions, such as hypocalcemia or hypercalcemia, which may require further investigation and management.

When evaluating serum calcium levels, it's also important to consider factors such as albumin levels, as calcium can bind to proteins and lower or elevate the free calcium levels reported on laboratory tests. Hence, maintaining calcium within this normal range is crucial for overall health and proper functioning of various biological systems.
