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 Renal Disease … WebPurpose of review: Glomerular filtration rate (GFR) is the best overall measure of kidney function. Reference GFR measurements (e.g. inulin clearance) are laborious. Estimation of GFR using equations based on endogenous filtration markers is simpler, cheaper and easy to apply in practice but suffers from limited accuracy and reproducibility.

WebClassic inulin clearance studies have been performed in premature and term neonates to provide data on (1) the reliability of inulin as a marker of GFR in human neonates, (2) the development of GFR in early postnatal life, and (3) the effect of disease states on GFR.
