Calculating creatinine clearance from gfr

WebA traditional method for estimating the GFR is to calculate the creatinine clearance from serum creatinine and a 24-hour urine collection. As indicated in the guidelines document, creatinine clearance is not an identical parameter to the GFR as tubular secretion and extra-renal creatinine loss lead to creatinine clearance exceeding the GFR. ... WebThe above formula only applies for GFR calculation when it is equal to the Clearance Rate. The normal range of GFR, adjusted for body surface area, is 100–130 average 125 (mL/min)/ (1.73 m 2) in men and 90–120 (mL/min)/ (1.73 m …
