What is this test?
➤ A creatinine clearance test compares the amount of creatinine in your blood to the amount in your urine over a 24-hour period. This shows how fast your kidneys clear creatinine from your body. Your doctor may ask you to do a creatinine clearance test to see how well your kidneys are working.
Test Preparations
➤ The first morning specimen should be discarded, record the time, and collect the succeeding for the next 24hrs.
➤ Avoid stool contamination.
