Creatinine Clearance

The formula for calculating Creatinine Clearance is

((140-age)*(ideal body weight in kg)) /((serum creat)*(72)) for men; times 0.85 for a female.

If they are enormously obese use your own fudge (low fat I hope) factor. I like to add an additional 20% to compensate my ideal body weight.
