|Serum magnesium, like serum potassium, is
often normal despite depletion of total body magnesium Intracellular levels of magnesium
are more accurate measures; however, there is often poor correlation of intracellular red
blood cell and intracellular mononuclear cell magnesiumand these may correlate poorly with
the magnesium content of muscle in different disease states Of the two, intracellular
mononuclear cell magnesium is a better indicator of the magnesium status of the heart For
example, in a recent study of patients in the coronary care unit, only 7.7% had low serum
magnesium levels, but 53% showed low levels of mononuclear cell magnesium.
