Erythrocyte potassium levels uniquely reveal your total body potassium status. Potassium is an abundant mineral that helps keep normal water balance between the cells and body fluids. Muscle contractions, nerve impulses and blood pressure rely on availability of potassium.
Minerals are important catalysts that spark many of the chemical reactions in your body. We need minerals like potassium for nerve transmission, digestion, antibody production, metabolism of nutrients, and more. Measuring mineral concentrations inside your erythrocytes (red blood cells) is one of the best ways to determine their adequacy.
