Normal magnesium range?

Normal magnesium range?

• A. 1.2-2.1
• B. 0.8-1.2
• C. 2.0-3.0
• D. 3.0-4.0

Answer: (A)

Magnesium in the blood is measured in mg/dL, and the range that’s generally considered normal is about 1.2 to 2.1 mg/dL. This window reflects the circulating portion of magnesium, even though most Mg is stored intracellularly or in bone, and the serum level serves as a practical indicator of overall magnesium status. Normal levels support proper nerve and muscle function and stable cardiac conduction. Values below 1.2 mg/dL indicate hypomagnesemia, which can lead to increased neuromuscular excitability and potential arrhythmias. Values above 2.1 mg/dL indicate hypermagnesemia, which can depress reflexes and respiratory function, especially in settings like kidney impairment or excessive magnesium administration. Among the given ranges, 1.2-2.1 mg/dL best fits the typical normal reference. The other ranges fall outside this normal window, either too low or too high.
