Calculators

CKD-EPI 2021

Race-free eGFR equation (Inker et al., NEJM 2021). Gold standard for kidney function estimation. Shows CKD stage G1–G5 with color-coded risk.

MDRD 4-Variable

Levey 4-variable MDRD formula. Useful for research and comparison with CKD-EPI. Supports both mg/dL and µmol/L input.

Cockcroft-Gault

Creatinine clearance (CrCl) with optional BSA adjustment. Widely used for drug dosing in clinical practice.

BSA & BMI

Body surface area via Mosteller, DuBois & DuBois, and Boyd formulas. BMI with WHO classification. Metric and imperial units.

CKD Staging

Results are automatically mapped to KDIGO CKD stages with color-coded risk indicators.

G1 ≥90 G2 60–89 G3a 45–59 G3b 30–44 G4 15–29 G5 <15
