24 Hr. Urine Urea

This laboratory investigation measures 24 Hr. Urine Urea using a urine specimen. It may help clinicians assess the relevant urinary analyte, understand aspects of kidney handling or metabolism, and investigate a concern identified from symptoms or other results. For timed collections, the complete collection period and correct storage are important; for random samples, follow the laboratory’s collection instructions. The result should be interpreted alongside clinical history, medicines, hydration, and other investigations.
