Hospital laboratories report kidney function using CKD-EPI 2021 eGFR because it accurately classifies Chronic Kidney Disease without race adjustments. However, pharmaceutical companies historically established drug dosage adjustment tiers (e.g. for Apixaban, Metformin, Enoxaparin) using Cockcroft-Gault CrCl. In elderly or low-weight patients, clinicians should use the more conservative estimate to prevent drug accumulation.
Laboratories often lack real-time patient weight and height data required for the Cockcroft-Gault formula, whereas CKD-EPI 2021 requires only serum creatinine, age, and biological sex.
