eGFR Calculator (2021 CKD-EPI Creatinine)

Clinical context

2021 CKD-EPI creatinine is currently recommended by the ASN and NKF for GFR reporting. GFR staging (mL/min/1.73m²): • G1 (normal or high): ≥90 • G2 (mildly decreased): 60–89 • G3a (mildly to moderately decreased): 45–59 • G3b (moderately to severely decreased): 30–44 • G4 (severely decreased): 15–29 • G5 (kidney failure): <15 Used equations for calculations: • Female (SCr ≤ 0.7 mg/dL): GFR = 142 × (SCr/0.7)^-0.241 × (0.9938)^Age × 1.012 • Female (SCr > 0.7 mg/dL): GFR = 142 × (SCr/0.7)^-1.200 × (0.9938)^Age × 1.012 • Male (SCr ≤ 0.9 mg/dL): GFR = 142 × (SCr/0.9)^-0.302 × (0.9938)^Age • Male (SCr > 0.9 mg/dL): GFR = 142 × (SCr/0.9)^-1.200 × (0.9938)^Age
