Potassium is an electrolyte, a substance that conducts electricity in the body, along with sodium, chloride, calcium, and magnesium. Potassium is crucial to heart function and plays a key role in skeletal and smooth muscle contraction, making it important for normal digestive and muscular function.
A variety of circumstances can falsely elevate potassium. These include the way a test is collected and processed. Clenching and relaxing your fists during the test can falsely elevate potassium. Delaying blood samples or rough handling can cause potassium to leak from blood cells. If the results are abnormal, a healthcare practitioner may suggest repeating the test.
This test requires a blood draw, which can be done at your local clinic. It will be analysed by an accredited lab, such as Karolinska, Synlab, or Unilabs. The first results are usually available within 48h.
No advance preparation is needed for this test.
