Estimated Glomerular Filtration Rate
Abbreviation: eGFR
Panel: Metabolic, Kidney & Electrolytes · All metabolic & kidney tests
Typical adult reference range
| Conventional units | ≥90 mL/min/1.73 m² |
| SI units | ≥90 mL/min/1.73 m² |
Ranges vary between laboratories and methods — compare your result with the range printed on your own report.
What a high or low result can mean
Low estimated glomerular filtration rate: persistently low values can be seen in chronic kidney disease.
These are associations, not a diagnosis: the same result can have several causes, and your clinician interprets it with the rest of your results and history.
Good to know
Estimated from creatinine (and sometimes cystatin C), age, and sex; it is not measured directly.
◆ Kidney note
This test is closely tied to kidney health, and it is one a kidney specialist (nephrologist) watches closely. On this site, kidney-related results are a special focus: see the kidney and dialysis medicines in our Drug Guide and the kidney condition hubs for the wider picture.
