Kidney Function

Estimated GFR (eGFR)

Q: What is the normal range for Estimated GFR (eGFR)?

The standard teaching reference range for Estimated GFR (eGFR) is ≥ 90 (normal kidney function) mL/min/1.73 m² in conventional units, or ≥ 90 mL/min/1.73 m² in SI units. This value is measured in serum creatinine (calculated). Reference ranges vary by laboratory, method, age, sex, and population - always use the range printed on the actual result.

Q: What causes a high Estimated GFR (eGFR)?

Common causes of a high Estimated GFR (eGFR): Normal or hyperfiltration (early diabetes).

Q: What causes a low Estimated GFR (eGFR)?

Common causes of a low Estimated GFR (eGFR): Chronic kidney disease (stages by eGFR); Acute kidney injury; Aging kidneys.

Q: What staging threshold is taught for Estimated GFR (eGFR)?

For Estimated GFR (eGFR), the commonly taught staging threshold is: < 15 mL/min/1.73 m² indicates kidney failure.

Normal range ≥ 90 (normal kidney function) mL/min/1.73 m² (≥ 90 mL/min/1.73 m² SI). Specimen: Serum creatinine (calculated).

Also known as: glomerular filtration rate, estimated GFR.

Reference range

This result is reported qualitatively or as a one-sided threshold rather than a two-sided numeric band.

Combined adult band. LabVals does not publish separate men's, women's, or pediatric ranges for Estimated GFR (eGFR); those can be narrower than the band shown.
