WebIt's easiest to see in the Cockcroft and Gault formula for converting creatinine to GFR: (140-age)/Creatinine -- plus a correction for weight whereby obesity actually means higher GFR. With a "normal" creatinine of 1 mg/dl, GFR is 100% when you're 40 yrs of age, but falls linearly thereafter. WebCreatinine clearance ( CrCl) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus). The additional proximal tubule secretion falsely elevates the CrCl estimate of GFR. 12. pine valley apartments in new castle delaware
