Test means, such as a composition, a test device, method of making the test device and process for determining glucose in a body fluid sample are disclosed. More particularly, the contemplated test means comprises glucose oxidase, a peroxidatively active substance, such as peroxidase, and a 3,3',5,5'-tetraalkylbenzidine indicator in an amount sufficient rapidly to produce upon contact of the test means with a predetermined amount of a glucose containing sample, a stable colored reaction product. The preferred benzidine indicator is 3,3',5,5'-tetramethylbenzidine.
