What is the normal range for serum calcium levels?

• A. 6.0 to 8.0 mg/dL
• B. 8.5 to 10.5 mg/dL
• C. 10.5 to 12.0 mg/dL
• D. 7.5 to 9.5 mg/dL

Answer: (B)

The normal range for serum calcium levels is recognized as 8.5 to 10.5 mg/dL. This range is crucial for various physiological functions, including muscle contraction, nerve transmission, and blood coagulation. Serum calcium is tightly regulated by hormones such as parathyroid hormone and calcitonin, and it is important for maintaining bone health and overall metabolic functions. Levels below or above this range can indicate clinical conditions, such as hypocalcemia or hypercalcemia, which can have significant health implications. Thus, understanding and recognizing the normal range is essential for diagnosing and managing potential disorders related to calcium imbalances.
