Use this eGFR calculator to estimate kidney function from age, sex, and serum creatinine. ClinFuse defaults to µmol/L, converts internally to mg/dL for the published CKD-EPI 2021 equation, and reports mL/min/1.73 m².

G1/G2 range if kidney damage markers are absent
Converted from µmol/L when selected.

eGFR = 142 × min(Scr/κ, 1)^α × max(Scr/κ, 1)^-1.200 × 0.9938^Age × 1.012 [if female]κ = 0.7 for female and 0.9 for male; α = -0.241 for female and -0.302 for male; Scr is serum creatinine in mg/dL.ClinFuse converts creatinine from µmol/L to mg/dL by dividing by 88.4 before applying the equation.eGFR is normalized to body surface area and is most useful for chronic kidney disease staging when renal function is stable.
Use caution in acute kidney injury, pregnancy, extremes of muscle mass, amputees, and rapidly changing creatinine values.
For drug dosing, creatinine clearance may still be requested in some prescribing references; see the Cockcroft-Gault calculator.
