Kidney Function
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.
This result is reported qualitatively or as a one-sided threshold rather than a two-sided numeric band.
| Specimen | Serum creatinine (calculated) |
|---|---|
| Conventional range | ≥ 90 (normal kidney function) mL/min/1.73 m² |
| SI range | ≥ 90 mL/min/1.73 m² |
| Conversion factor | ×1 (conventional → SI) |
| Critical value | < 15 mL/min/1.73 m² indicates kidney failure |

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).
A commonly taught critical (panic) value is < 15 mL/min/1.73 m² indicates kidney failure. Critical results are reported to the provider immediately under your facility's policy.
