In clinical practice, however, creatinine clearance or estimates of creatinine clearance based on the serum creatinine level are used to measure GFR. Creatinine is produced naturally by the body (creatinine is a breakdown product of creatine phosphate, which is found in muscle). It is freely filtered by the glomerulus, but also actively secreted by the peritubular capillaries in very small amounts such that creatinine clearance overestimates actual GFR by 10% to 20%. This margin o… WebJun 1, 2002 · Dr. Matz has suggested the use of oral cimetidine to improve the accuracy and predictive capacity of the Cockcroft-Gault equation to estimate glomerular filtration rate …
