Aside from increased sensitivity, what major advantage does glucose oxidase offer over fehling/'s reagent for measuring blood glucose?

The major advantage that glucose oxidase method has over Fehling reagent for blood glucose measurement is that glucose oxidase method is specific for glucose measurement. The Fehling method gives positive result to glucose detection as well as for alcohols and aldehydes. This means that the test is not specific for glucose only. Also, the Fehling method can only be used in an alkaline environment.
