Normal serum potassium values vary with technique used by the laboratory but are usually between 3.5 and 5 mEq/L. Hypokalemia is defined as a serum potassium <3.5 mEq/L. Mild hypokalemia is 3.0–3.5 mEq/L. Moderate hypokalemia is 2.5–3.0 mEq/L; severe hypokalemia is <2.5 mEq/L. Severe hypokalemia can cause cardiac arrhythmias.
