Creatinine clearance is primarily a renal function test based on the rate of excretion by the kidneys of metabolically produced creatinine. It involves the glomerular filtration rate (GFR) and renal plasma flow. It is therefore used to estimate the GFR. Values fall early in patients who subsequently develop acute renal failure. Values are reported in mgs of creatinine per 24 hours, utilizing the values of serum or plasma creatinine, urine creatinine, and the total volume of urine excreted in a 24 hour period.

Please specify on the request form if the sample is a 24-hour
urine or a timed urine (not 24-hour). Please indicate the
total urine volume and the start and end time of collection
on the request form.
