Enzymic determination of serum oxalate.
A new colorimetric, enzymic method for determination of serum oxalate is described using oxalate oxidase from barley seedlings. This method, based on a specific reaction of oxalate with oxidase is rapid, simple and precise. The percentage recoveries of oxalate added to serum ranged from 91.5 to 103. The oxalate content in the serum obtained from 50 healthy non-fasting donors varied from 0.06 mg/dl to 0.41 mg/dl. The proposed method showed a good correlation with a chemical method.
