Is there a role for routine estimations of plasma magnesium?
The inclusion of magnesium in a blood chemistry profile has resulted in the detection of potentially significant abnormalities in 2.7% of specimens analyzed. Hypomagnesaemia occurs most often in patients treated with intravenous fluids or diuretics, and hypermagnesaemia in patients with renal failure. Hypomagnesaemia is often associated with abnormalities of potassium or calcium metabolism. Inclusion of magnesium in a routine blood chemistry profile is not clinically justified.
