Evaluation of renal function
1-4 years: 0.2 - 0.6 mg/dL, 5-11 years: 0.4 - 0.9 mg/dL, 12-150 years, male: 0.7 - 1.3 mg/dL, female: 0.5 - 1.0 mg/dL

The CKD-EPI equation should not be used to predict EGFR in unstable patients or in children. A GFR estimate between 15 and 59 for ? 3 months is classified as Chronic Kidney Disease (Stage 3 or 4).
GFR estimate can be interpreted accurately only during a steady state of creatinine balance. GFR estimate will overestimate true GFR if serum creatinine is rising (such as acute kidney failure) and will underestimate true GFR if serum creatinine is declining (such as resolution of acute kidney failure).
EGFR is not calculated when serum creatinine values are <0.1mg/dL.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
