SODIUM & POTASSIUM (Na & K)

No patient preparation is needed.

Sodium is critical in maintaining water and osmotic equilibrium in extracellular fluids. Disturbances in acid base and water balance are typically reflected in sodium concentrations. Potassium is an essential element involved in critical cell functions. Potassium levels are influenced by electrolyte intake, excretion and other means of elimination, exercise, hydration and medications.
