Parameter	Value
Age (years)
Sex	1 Male   Female
Weight (kg)
Serum Creatinine (mg/dL)
CrCl (mL/min)	mL/min

Interpretation
>90	Normal renal function.
60–89	Mildly decreased (CKD Stage 2).
30–59	Moderately decreased (CKD Stage 3). Adjust renally-dosed medications.
15–29	Severely decreased (CKD Stage 4).
<15	Kidney failure (CKD Stage 5). Consider dialysis.

Cockcroft DW, Gault MH. Prediction of creatinine clearance from serum creatinine. Nephron. 1976;16(1):31-41. PMID 1244564. Formula: CrCl = [(140 − age) × weight (kg)] / [72 × serum Cr (mg/dL)] × 0.85 if female. Note: Use IBW or adjusted BW in obese patients. Not validated in AKI or rapidly changing creatinine.
