What is potassium?
Potassium is an important mineral for the function of nerves, muscles and the heart, and for the regulation of fluid balance. The amount of potassium in the blood is kept at low levels and alterations may indicate underlying problems such as kidney disease, high blood pressure or an irregular heartbeat.
Why take this test?
This test measures the level of potassium in the blood and can be used to investigate conditions associated with potassium changes such as kidney disease, high blood pressure or an irregular heartbeat.
