What is the normal range of total calcium in mmol/L?

Total calcium plays a crucial role in various physiological processes, including muscle contraction, blood coagulation, and nerve conduction. The normal range for total calcium in the bloodstream is typically reported in millimoles per liter (mmol/L), and this range is approximately 2.2 to 2.6 mmol/L. This value represents the concentration of calcium that is normally found in healthy adults, ensuring that bodily functions reliant on calcium have the necessary resources for optimal performance.

The other ranges presented do not accurately reflect the normal physiological levels of total calcium. Understanding that the body's calcium levels are tightly regulated by hormones such as parathyroid hormone, vitamin D, and calcitonin emphasizes the need to maintain this specific range for overall health and metabolic functions. Knowledge of these values is essential for healthcare professionals in assessing and managing patients in various clinical settings.
