GFR
Glomerular filtration rate as a measure of kidney function
Also known as
glomerular filtration rate eGFR estimated GFR kidney filtration
Definition
The glomerular filtration rate (GFR) describes the volume of plasma filtered by the renal glomeruli per minute and is the primary measure of kidney function. In practice, eGFR is calculated from creatinine, age, and sex using the CKD-EPI formula. A value below 60 ml/min/1.73 m² persisting for more than three months defines chronic kidney disease.
| Parameter | Value |
|---|---|
| Unit | ml/min/1.73 m² |
| Reference Range | > 90 ml/min/1.73 m² (normal kidney function) |
| Optimal Range (lab2go) | > 90 ml/min/1.73 m² |
