ⓘ The CKD-EPI 2021 equation is the current international gold standard for estimating GFR. It does not use race as a variable — making it fully applicable to Indian patients. Serum creatinine should be measured in a fasting state for best accuracy.

Please enter valid age (18+) and serum creatinine (0.1 to 20 mg/dL).

ⓘ For educational purposes only. Not a substitute for physician judgment. eGFR calculated using CKD-EPI 2021 creatinine equation (Inker LA et al., NEJM 2021;385:1737–1749). CKD staging per KDIGO 2022 Clinical Practice Guidelines. eGFR is an estimate. Not validated for acute kidney injury, pregnancy, extremes of muscle mass, or amputees. Abnormalities should be confirmed over at least 3 months before diagnosing CKD.
