Clinical Significance

Evaluate renal function, electrolyte balance studies, acid-base balance, water balance.

The role of electrolytes in the human body is manifold. There are almost no metabolic processes that are not dependent on or affected by electrolytes. Among other functions of the electrolytes are maintenance of osmotic pressure and water distribution in the various body fluid compartments, maintenance of the proper pH, regulation of the proper function of the heart and other muscles, involvement in oxidation-reduction reactions, and participation in catalysis of cofactors for enzymes.
