🫘 eGFR Calculator (CKD-EPI 2021)
Estimate GFR with the race-free CKD-EPI 2021 creatinine equation for CKD staging.

Sex
When to use
Assess and stage chronic kidney disease (with albuminuria).
How it works
CKD-EPI 2021: 142 × min(SCr/κ,1)^α × max(SCr/κ,1)^−1.200 × 0.9938^age × (1.012 if female); κ=0.7/0.9, α=−0.241/−0.302.
Key points
- Race-free 2021 equation, reported per 1.73 m².
- Confirm eGFR < 60 over ≥ 3 months for CKD.
- Combine with albuminuria for KDIGO category.
