Test Detail

Potassium, Urine 24H

A 24-hour urine potassium test measures the amount of potassium excreted by the kidneys over a full day, which helps diagnose conditions like high or low potassium levels in the body and kidney problems. The normal range for adults is typically between 25 to 125 mEq/day or mmol/day, but this can vary by lab and is influenced by diet. The test requires collecting all urine over 24 hours in a special container, and results indicate potential imbalances caused by kidney function, medications, or dietary factors.
