Test Description: Potassium – Urine 24-Hours

The 24-Hour Urine Potassium test measures the amount of potassium excreted in the urine over a 24-hour period. Potassium is a crucial electrolyte that helps regulate fluid balance, nerve function, and muscle contractions. This test is used to assess kidney function, electrolyte imbalances, and conditions such as hypertension, kidney disease, or hormonal disorders like hyperaldosteronism. Abnormal potassium levels in urine may indicate issues with kidney function, dehydration, or excessive intake or loss of potassium from the body.
