eGFR
Also written as: eGFR — estimated glomerular filtration rate
A calculated measure of kidney function based on serum creatinine, age, sex, and race. Used to stage chronic kidney disease in pediatric patients.
Full Definition
The estimated glomerular filtration rate is a calculated value derived from serum creatinine levels, patient demographics, and validated equations such as the Schwartz formula in children. It provides a standardized assessment of kidney function that accounts for body surface area differences in pediatric populations. eGFR values help classify the severity of kidney disease and guide treatment decisions, with normal values varying by age in children.
Usage
Usage note: Always lowercase 'e' when used as acronym; distinguish from measured GFR in clinical contexts.
