A partial list of magnesium measurement methods used to determine magnesium status. Please note that serum magnesium level is still the most widely practiced method of determining magnesium status in health and disease [19,20,21,22,23,24].

▪ Total serum magnesium

▪ Oral magnesium loading test

▪ Intravenous magnesium loading test

▪ RBC magnesium content

▪ Hair magnesium content

▪ Muscle magnesium content (biopsy)

▪ Bone magnesium content

▪ 24-h urinary magnesium

▪ The ratio of ionized to total magnesium

RBC, red blood cell.
