Your doctor may ask you to do a creatinine clearance test to see how well your kidneys are working. This shows how fast your kidneys clear creatinine from your body. It’s normally filtered from your blood by your kidneys and cleared (removed) from your body in your urine.Ī creatinine clearance test compares the amount of creatinine in your blood to the amount in your urine over a 24-hour period. Back to top About Your Creatinine Clearance TestĬreatinine is a substance in your blood.

Doses of some drugs may need to be adjusted.Ĭomplete and accurately timed urine collections are essential.This information explains how to collect and store your urine (pee) for your creatinine clearance test. This may indicate acute or chronic kidney disease. Reduced creatinine clearance is an indicator of reduced glomerular filtration rate (GFR). Measured creatinine clearance is of particular use in patients with extremes of body size or composition where estimation formulae may be unreliable.

Typically falling approx 0.5 mL/min per year at ages over 30 years.Ĭreatinine clearance is a marker of glomerular filtration rate (GFR). The patient should not eat meat at the meal immediately prior to, or during, the procedure.Ī calculated value using serum and urine creatinine.Ĭreatinine clearance (mL/min) = urine creatinine (mmol/L) x urine volume (mL) x 16.7 / plasma creatinine (mmol/L) x duration of collection (hours) The patient's height and weight may be measured so that surface area can be calculated and creatinine clearance adjusted to the 'standard' body surface area of 1.73m 2 if required.Ĭreatinine clearance may be estimated rather than measured -see Creatinine clearance Cockcroft and Gault.
