What is the normal range for blood calcium levels?

The normal range for blood calcium levels typically falls between 8.5 and 10.2 milligrams per deciliter (mg/dL), though this may vary slightly depending on the laboratory. Levels below this range indicate hypocalcemia, while levels above suggest hypercalcemia. Maintaining calcium within this range is crucial for bone health, muscle function, and other physiological processes. Abnormal results often warrant further investigation to identify underlying conditions.
