Urine Urea 24 Hours is a test that measures the amount of urea excreted in the urine over a 24-hour period. Urea is a waste product produced by the liver from the breakdown of proteins and is eliminated through the kidneys.

This test is often used to evaluate kidney function, protein metabolism, and nitrogen balance in the body. It can help diagnose conditions like kidney disease, liver disease, or protein disorders. Abnormal urea excretion can indicate either impaired kidney function or changes in dietary protein intake.
