Serum Creatinine mg/dL

Additional markers (optional — for complete CKD staging)

Urine ACR Albumin-to-Creatinine Ratio (mg/g)

Previous Creatinine mg/dL — for trend analysis

Relevant conditions

Diabetes mellitus

Leading cause of CKD in India

Hypertension

Regular NSAID / painkiller use

Ibuprofen, Diclofenac, Nimesulide

Contrast dye procedure planned

Angiogram, CT with contrast

ⓘ 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 clinical decision support 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 — actual GFR may vary. Not validated for acute kidney injury, pregnancy, extremes of muscle mass, or amputees. Single measurements should not be used to diagnose CKD; abnormalities should be confirmed over at least 3 months.
