Creatinine

Increased creatinine levels usually indicate renal function impairment but would not be considered a sensitive indicator of early renal disease.  Plasma concentrations can be more sensitive to changes in glomerular function where a chronic renal disease state exists. Urinary creatinine is only useful when performed as part of a creatinine clearance test.  In these circumstances it is useful verification of the completeness of a 24 hour urine collection.

The Biorex Diagnostics Creatinine reagents are intended for quantitative in-vitro determination of Creatinine in serum/plasma and urine.
