Potassium Test
 
 

Potassium assists nerves and muscles to communicate. It also is involved in transporting nutrients into cells and moving waste materials out of cells. A potassium blood test evaluates the amount of potassium in blood. Potassium tests may be ordered to check for kidney disease, for signs of heart problems or if an individual has high blood pressure. Potassium plays a role in the activity of the heart and improper potassium levels can lead to an irregular heartbeat or an electrical malfunction of the heart.
