  • Patent number: 5543299
    Abstract: The invention relates to polymeric compositions useful in analyte determination. The compositions contain a polymer, a reagent system for analyte determination, and an extender. The last component alleviates tackiness in the composition, and thus reduces damage in preparation of test apparatus. Mica is the particularly preferred extender.
