GFR Calculator
Estimates your glomerular filtration rate, a key kidney function number, from a creatinine blood test result.
How this calculator works
Uses the CKD-EPI 2021 race-free creatinine equation: eGFR = 142 × min(Scr/κ,1)^α × max(Scr/κ,1)^−1.200 × 0.9938^age × 1.012 (if female), with κ = 0.7 (F) / 0.9 (M) and α = −0.241 (F) / −0.302 (M). Stages follow KDIGO.
