DescriptionMeasured as part of the U/E profile. **PLEASE NOTE: THE REFERENCE RANGE FOR THIS TEST WAS CHANGED MONDAY OCTOBER 3RD 2011**
IndicationInvestigation of renal function.
Additional InfoNB Creatinine is related to muscle mass so women and children tend to have lower levels than men. It is therefore important to remember that a frail old lady may have a creatinine within the reference range which is actually indicative of a problem. Creatinine levels are inversely related to the GFR and so there can be a considerable fall in the GFR before serum creatinine levels begin to rise.
