Abstract
An analytical element for quantitatively determining high levels of glucose in blood is made by (a) impregnating a carrier with a first solution, having dissolved therein 4-aminoantipyrine and 3-hydroxy-2,4,6-triiodobenzoic acid or 3,5-dichloro-2-hydroxy-benzene sulfonic acid or salts thereof, a glucose oxidase and a peroxidase, and drying the carrier; and (b) applying to the carrier a second solution of a film-forming agent in a volatile solvent, and drying to remove the volatile solvent and leave a film over the dried first impregnant.
