Potassium

Normal potassium level in the blood is maintained at a strict level between 3.5 to 5 millimoles per liter. A potassium level greater than 5 millimoles per liter is considered high potassium also called hyperkalemia and a potassium level lower than 3.5 millimoles per liter is considered hypokalemia.
