Routine serum magnesium determination: a contemporary clinical imperative.
Identification of hypomagnesaemia or hypermagnesaemia is presently the most expeditious method of clinically identifying perturbations in Mg metabolism. Clinicians may overlook as much as 90% of clinical hypomagnesaemia and hypermagnesaemia when serum Mg is determined on order versus on a routine basis. Routine serum Mg determination will facilitate management of digitalis toxicity in patients who are not currently identified as being hypomagnesaemic as well as preventing the occurrence of refractory K repletion. In our opinion routine serum Mg determination represents a clinical need which has not been addressed to date.
