Determine the renal function stage and general dose adjustment guidance based on GFR.
Formula
GFR staging: Normal ≥90, Mild 60–89, Moderate 30–59, Severe 15–29, ESRD <15 mL/min/1.73m².

Clinical
Calculate estimated glomerular filtration rate (eGFR) using the CKD-EPI 2021 equation. Assess kidney function and 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)
