When to use it. Staging chronic kidney disease and tracking kidney function over time in adults.

Limits of this score. Only valid in steady state. In acute kidney injury the creatinine is still chasing the true GFR, so the estimate is meaningless. It is also unreliable at extremes of muscle mass — amputees, bodybuilders, advanced cirrhosis — and in pregnancy. For drug dosing, check whether the label specifies Cockcroft-Gault instead.
