Potassium Blood Test

A Potassium Test measures the level of potassium present in your blood. The normal potassium range typically lies between 3.5 to 5.0 mEq/L.

• High Potassium (Hyperkalemia):

  Occurs when potassium levels rise above 5.0 mEq/L and becomes severe above 8.0 mEq/L.

  It is commonly caused by:

  • Kidney failure

  • Potassium supplements

  • Severe dehydration

  • Certain medicines

    Hyperkalemia can cause dangerous heart rhythm disturbances and sudden cardiac arrest.

• Low Potassium (Hypokalemia):

  Occurs when potassium falls below 3.0 mEq/L and may result from:

  • Diarrhea and vomiting

  • Excessive sweating

  • Starvation or eating disorders

  • Diuretic medications

    Severe hypokalemia can cause paralysis, respiratory failure, and heart rhythm problems.

Hence, the Potassium Test is critical for early detection and prevention of life-threatening complications.

The Potassium Test is a simple blood test that evaluates potassium concentration to assess heart, muscle, and kidney health. It is commonly ordered as a part of the Electrolyte Panel along with Sodium and Chloride tests.
