WebCockcroft-Gault formula: Estimated creatinine clearance rate (eCCR) Creatinine clearance can be estimated using serum creatinine levels. The Cockcroft-Gault (C-G) formula uses a patient’s weight (kg) and gender to predict CrCl (mg/dL). The resulting CrCl is multiplied by 0.85 if the patient is female to correct for the lower CrCl in females. Web1 Jul 2024 · The equation used for the calculation of GFR is: Cs = (Us × V)/Ps Where Cs is the volume of plasma cleared of the substance per minute, Us is the urinary concentration of the substance, V is the volume of urine produced per minute and Ps is the plasma concentration of the substance.
