Side-by-side comparison helps you choose the right calculator for a specific clinical question.
Clinical
Calculate estimated glomerular filtration rate (eGFR) using the CKD-EPI 2021 race-free equation. Free kidney function assessment with CKD staging from serum creatinine.
Formula
CKD-EPI 2021: 142 × min(Scr/κ, 1)^α × max(Scr/κ, 1)^-1.200 × 0.9938^Age × (1.012 if female)
Inputs
Clinical
Calculate creatinine clearance (CrCl) using the Cockcroft-Gault equation. Used for renal drug dosing adjustments based on kidney function.
Formula
CrCl = [(140 − age) × weight] / (72 × Scr) × 0.85 if female
