The normal range for calcium levels in adults is 8.5-10.5 mg/dL. This range is significant because calcium plays essential roles in various physiological processes, including bone health, muscle function, nerve transmission, and blood clotting. Maintaining calcium levels within this range ensures that these functions operate effectively.

Calcium levels that fall below or above this range may indicate underlying health issues. For example, levels below 8.5 mg/dL can suggest hypocalcemia, which may result from conditions such as vitamin D deficiency or parathyroid hormone dysfunction. Conversely, levels above 10.5 mg/dL may indicate hypercalcemia, which can arise from conditions like hyperparathyroidism or malignancies. Understanding the normal calcium range is crucial for diagnosing and managing various medical conditions effectively.
