What is the normal concentration range for serum calcium levels?

The normal concentration range for serum calcium levels is indeed 8.5-10.5 mg/dL. This range is accepted as the reference interval in most clinical settings and is crucial for various physiological functions. Calcium plays a significant role in bone health, muscle contraction, nerve transmission, and blood coagulation. Maintaining serum calcium levels within this range is essential for physiological stability. Deviations from this normal range can indicate underlying health issues; for example, low levels (hypocalcemia) may suggest vitamin D deficiency or parathyroid hormone problems, while high levels (hypercalcemia) can indicate hyperparathyroidism or malignancy.

Understanding the normal serum calcium levels helps in diagnosing and managing conditions related to calcium metabolism and can guide healthcare professionals in their clinical decision-making processes. This knowledge is vital for medical technologists who may analyze serum calcium levels as part of a comprehensive metabolic panel.
