24 Hours Urinary Creatinine

The 24-Hour Urinary Creatinine Test is a laboratory investigation used to measure the total amount of creatinine excreted in urine over a 24-hour period.

Creatinine is a waste product produced by normal muscle metabolism and removed from the body primarily through the kidneys. This test helps healthcare professionals evaluate creatinine excretion and assess kidney function. It may also be used as part of a creatinine clearance assessment.
