Urea Nitrogen 24 Hour Urine Test

The Urea Nitrogen 24 Hour Urine Test measures nitrogen excreted over a full day to evaluate protein metabolism and kidney function. Elevated levels may reflect high protein intake, catabolic states, or certain metabolic conditions, while decreased levels can indicate malnutrition, liver disease, or impaired renal function. This test provides valuable insight into nutritional balance, metabolic health, and renal performance.

The Urea Nitrogen 24 Hour Urine Test test contains 1 test with 1 biomarker .

About 80% of urinary nitrogen is in the form of urea which is the major end product of protein metabolism. Urea excreted in the urine is the primary method of nitrogen elimination; therefore, this test provides an approximate evaluation of nitrogen balance. Conditions associated with increased urine urea nitrogen are hyperthyroidism, high protein diets and post-operative states. Decreased levels are associated with convalescence, liver disease, toxemia and advanced renal disease.
