Notes
  • To calculate the creatinine clearance from a 24-hour urine collection, enter your patient's data into the appropriate data fields. The serum creatinine concentration must be stable for this formula to be valid. (Refer to UpToDate topic reviews that discuss calculation of the creatinine clearance for a review of the factors that limit the accuracy of this test.)

 
Equations used
 
Creatinine_clearance = Urine_creatinine * 24-hour urine volume / Serum_creatinine / 1440

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
