Above the range
What causes a high Estimated GFR (eGFR)?
Normal range ≥ 90 (normal kidney function) mL/min/1.73 m² (≥ 90 mL/min/1.73 m² SI). Specimen: Serum creatinine (calculated). See the full Estimated GFR (eGFR) reference page for the taught thresholds and nursing considerations.
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).
| Specimen | Serum creatinine (calculated) |
|---|---|
| Conventional range | ≥ 90 (normal kidney function) mL/min/1.73 m² |
| SI range | ≥ 90 mL/min/1.73 m² |
| Staging threshold | < 15 mL/min/1.73 m² indicates kidney failure |
