Magnesium: Serum magnesium levels do not reflect total body magnesium stores. RBC magnesium is a better reflection of total body magnesium levels. Few doctors know this or will order an RBC magnesium. Thus many patients who are total body magnesium deficient are total they are fine because of a normal serum magnesium level.
