DescriptionPart of U&E profile. Although potassium is predominantly an intracellular ion, it is the serum concentration that is of immediate importance in therapy. Severe hyperkalaemia or hypokalaemia, if severe, must be treated immediately. Hypokalaemia is usually the result of potassium depletion and hyperkalaemia occurs most commonly when the rate of potassium leaving the cells is greater than its rate of excretion.
