24 HOUR URINE UREA

A 24-hour urine urea test is advised by a doctor to assess kidney function in people with chronic kidney disease or those on dialysis. It is also used to evaluate protein intake, nutritional status, and nitrogen balance in hospitalized, critically ill, or malnourished patients, and in people with burns, trauma, or major surgery.

To prepare for a 24-hour urine urea test, discard your first morning urine and note the time. Then collect all urine for the next 24 hours in the container provided, including the next morning's first sample. Keep the container refrigerated. Follow your usual diet unless advised otherwise, drink fluids normally, and inform your doctor about any medicines.

No, fasting is not required for a 24-hour urine urea test. You should eat your usual diet during the collection period unless your doctor advises otherwise, as the test reflects your normal protein intake. Drink fluids normally, and collect every urine sample over the full 24 hours for accurate results.
