What is being tested?

Potassium is present in all body fluids, but most potassium is within your cells. Only a very small amount of potassium is contained within the serum or plasma component of the blood. In health, the amount of potassium within serum is tightly controlled, however, many illnesses / drugs can cause concentrations of potassium to become too high or too low. An abnormal concentration can alter the function of the nerves and muscles including those of the heart.I In extreme cases you may experience disturbances to your heart beat or the heart muscle may even lose its ability to contract.

How is the sample collected for testing?

A blood sample is taken by needle from a vein in the arm.
