Calculator
How it works and when to use it
The calculator uses the 2021 CKD-EPI creatinine equation, the one recommended today without a race term, and takes creatinine in mg/dL or µmol/L.
KDIGO stages: G1 normal or high (90 or more), G2 mildly decreased (60 to 89), G3a (45 to 59), G3b (30 to 44), G4 (15 to 29), G5 kidney failure (under 15), and chronic kidney disease needs the fall to last 3 months or other markers of damage.

Frequently asked questions
Does one low eGFR mean chronic kidney disease?
No, chronic kidney disease needs the fall to last more than 3 months, or markers of damage such as albumin in the urine.
When is the result not accurate?
With very high or very low muscle mass, amputation, pregnancy and acute kidney injury, where cystatin C can help.
Why was the race term removed?
The 2021 version was refitted without race, to avoid the estimation errors linked to it.
