Steps

  1. 1Ccr = (140 − 60) × 65 ÷ (72 × 1.20)
  2. 2= 5200 ÷ 86.4 = 60.2 mL/min
  3. 3Drug dosing uses CrCl (not eGFR) for many labels — e.g., metformin contraindicated <30, DOACs need adjustment <50

💡 Cockcroft-Gault (1976) estimates creatinine clearance from a blood sample — it predates CKD-EPI eGFR but remains the dosing reference on most drug labels. It overestimates in obesity (uses actual weight; some clinicians use adjusted/ideal weight instead). Not valid in acute kidney injury, pregnancy, severe edema, or extremes of muscle mass.
