What is the normal range for calcium levels in the body?

The normal range for calcium levels in the body is typically between 8.5 to 10.5 mg/dL. This range is essential because calcium plays a critical role in several bodily functions, including bone formation, neuromuscular function, and blood clotting. Maintaining calcium levels within this range is vital for physiological processes and overall health.

Levels below or above this range can indicate various health issues. For instance, low calcium levels, known as hypocalcemia, can result from conditions such as vitamin D deficiency, certain medications, or parathyroid hormone dysfunction. Conversely, high calcium levels, or hypercalcemia, can result from conditions such as hyperparathyroidism or malignancies. Understanding the normal range helps healthcare providers assess and manage patients effectively, ensuring any deviations are investigated and treated appropriately.
