Creatinine Clearance & Weight Charts

This guidance is for NHS Lothian staff to calculate creatinine clearance. 

If available, use the calculator (NB: intranet only)

CrCl (ml/min) = [ (140 - Age) X {weight* X 1.23(male) or 1.04(female)} ] / Serum creatinine**) 

*Use actual or Maximum Body weight, whichever is the lower

**If Cr <60 mmol/L, use a value of 60
