What Does a High Potassium Blood Level Mean?
Potassium is essential to many vital processes in the body. Potassium is involved in the proper functioning of nerve and muscle cells, digestion, metabolism and maintaining the balance of both electrical and chemical processes in the body. Potassium is especially important in cardiac function. MayoClinic.com explains that normal serum potassium levels range between 3.6 and 4.8 mEq/L. A high level of potassium in the blood is often indicative of an underlying kidney dysfunction.
