What is the acceptable range for magnesium levels in the blood?

The acceptable range for magnesium levels in the blood is crucial for understanding electrolyte balance and overall health. The correct range for serum magnesium is typically between 1.5 to 2.5 mmol/L. This range is important because magnesium plays a vital role in numerous biochemical functions within the body, including muscle contraction, nerve function, and the synthesis of DNA and proteins.

When considering the correct range, it reflects the balance needed for physiological functions; levels too low can lead to symptoms like muscle cramps or arrhythmias, while levels too high may result from renal failure or excessive intake and can cause neuromuscular disturbances.

The range of 0.5-2.0 mmol/L does not encompass the normal physiological levels. It could imply deficiency since it's lower than the accepted range. The range of 0.7-9.5 mmol/L is excessively broad and includes values far higher than typical physiological levels, indicating possible error in measurement or interpretation as it includes critical hypermagnesemia. Lastly, while the range of 1.0-5.0 mmol/L starts at a more acceptable lower boundary, the upper limit is too high and does not accurately reflect the normal limits for healthy individuals.

Thus, confirming normal magnesium levels is
