Test Description: Phosphorus Urine, 24-Hours

The 24-Hour Urine Phosphorus test measures the amount of phosphorus excreted in the urine over a 24-hour period. Phosphorus is a mineral essential for bone health, energy production, and cellular function. This test helps assess kidney function, bone health, and the body’s phosphorus balance. Abnormal levels may indicate conditions such as kidney disease, hyperparathyroidism, or bone disorders. It is often used to evaluate calcium and phosphorus metabolism and detect potential deficiencies or imbalances.
