The Cockcroft-Gault Equation may be inaccurate depending on a patient's body weight and BMI; by providing additional height, we can calculate BMI and provide a modified estimate and range.

Advice

After calculating a creatinine clearance, providers should consider calculating an actual GFR as well, to determine the staging/severity of a patient's chronic kidney disease.

CKD stage GFR level (mL/min/1.73 m2)
Stage 1 ≥ 90
Stage 2 60 – 89
Stage 3 30 – 59
Stage 4 15 – 29
Stage 5 < 15
