WebSep 1, 2024 · Background: The 24-hour (24-h) creatinine clearance (CrCl) is the most common method for measuring GFR in clinical laboratories. However, the limitations of CrCl have resulted in the widespread acceptance of mathematically derived estimated glomerular filtration rate (eGFR) using Cockcroft-Gault (CG), Modification of Diet in … WebCreatinine clearance is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Creatinine clearance exceeds GFR due to creatinine secretion, [3] which can be blocked by cimetidine.

WebFeb 17, 2024 · A glomerular filtration rate (GFR) test measures how well your kidneys are carrying out their filtration function. This test usually involves testing your blood for a waste product called creatinine. WebThis means that the creatinine level in the blood stream can be used to track how well the kidneys are clearing waste products: if a person’s kidney function falls, their creatinine level will go up. Creatinine clearance (measuring how much creatinine a person makes in 24 hours) can give a reasonable estimate of actual GFR.
