creatinine clearance

Creatinine clearance is a medical test that measures how well your kidneys are filtering a waste product called creatinine from your blood. Creatinine is produced by muscle metabolism and is usually removed from the body through urine. By comparing the amount of creatinine in your blood to the amount in your urine over a 24-hour period, doctors can assess kidney function. A higher clearance rate indicates better kidney function, while a lower rate may suggest kidney impairment. This test helps healthcare providers diagnose and monitor conditions related to kidney health.
