Creatinine clearance

 In pediatrics, it is generally corrected to a body surface area of 1.73 m2 (standard body surface area of an adult).

Corrected CrCl (mL/min/1.73*m2) =

The formula for the calculation is as below. The BSA here is calculated from the height and weight with the formula of DuBois and DuBois.

CrCl = UCr * UVol
PCr * Tmin

Corrected CrCl = CrCl * 1.73

Reference range in our laboratory of an "uncorrected" creatinine clearance for an adult male is 90-139 mL/minute, and for an adult female is 80-125 mL/minute. Many medications must be adjusted for renal impairment when the CrCl falls below 50 mL/min.
