What tests are used to diagnose hyperkalemia?

ANSWER

Lab tests may be done to check the level of potassium in your blood and urine. Blood test results vary from lab to lab. Your doctor will explain your specific results. Many different factors can affect your potassium level. If your potassium level appears high, your doctor will likely repeat the blood test.

An electrocardiogram, commonly known as ECG or EKG, will be done to check for problems with your heart rhythm. This test records your heart's electrical activity.

Not every person with hyperkalemia has changes that can be seen on an ECG. Sometimes, changes that are seen may be mistakenly attributed to another disease.
