Abstract
A composition useful in determining analytes, such as glucose or cholesterol, is disclosed. The composition contains an enzyme which specifically reacts with the analyte to be determined, a soluble ferricyanide compound which is reducible to form a ferrocyanide, a soluble ferric compound which provides ferric ions for reacting with ferrocyanide to form a reaction product, and a buffer which does not prevent formation of this reaction product. The composition has a pH of from about 3.0 to about 6.0.
