Interpreting Potassium results

Interpretations

Normal range: 3.5 to 5.0mmol/L (136.5 to 195μg/ml approx.)

Hypokalemia: Below 3.5mmol/L (Less than 136.5μg/ml approx.)

Hyperkalemia: Above 5.0mmol/L (Above 195μg/ml approx.)

Potassium concentration in the body is maintained within a narrow normal range between 3.5mmol/L and 5.0mmol/L.

Hypokalemia or low blood potassium is indicated if potassium concentration lies below the normal range.

Hyperkalemia or high blood potassium is indicated if potassium concentration lies above the normal range.
