Abstract
A method of depositing reagent on an electrochemical test sensor adapted to determine information relating to an analyte includes providing a base and forming an electrode pattern on the base. The method further includes depositing the reagent on at least the electrode pattern using a reagent-dispensing system. The reagent-dispensing system applies mechanical force to the reagent in the reagent-dispensing system to assist in providing a wet reagent droplet on at least the electrode pattern.
Claims20
An electrochemical test sensor comprising a base, a lid, a plurality of electrodes and a dried reagent, the dried reagent comprise an enzyme, a mediator, a cellulose polymer and a multivalent salt such that dried reagent has a uniformity in which the ratio of the thinnest point to the thickest point is greater than about 0.2, the enzyme including glucose dehydrogenase, the mediator including a 3-phenylimino-3H-phenothiazine or a 3-phenylimino-3H-phenoxazine.
