What is the normal serum level range for magnesium?

• A. 1.0-1.5 mg/dL
• B. 1.7-2.2 mg/dL
• C. 2.5-3.0 mg/dL
• D. 3.5-4.0 mg/dL

Answer: (B)

The normal serum level range for magnesium is indeed between 1.7 and 2.2 mg/dL. This range is important for various physiological functions, including the regulation of muscle and nerve function, blood glucose control, and blood pressure regulation. Magnesium also plays a critical role in bone development and the production of protein. Maintaining this serum level is crucial, as both deficiency and excess can lead to significant health issues, such as muscle cramps, arrhythmias, and metabolic disturbances. Monitoring magnesium levels is particularly important in clinical settings where imbalances may occur, such as in patients with renal dysfunction or conditions that affect electrolyte absorption.
