Abstract
A method for the detection of a predetermined substance in a fluid is described. The method uses a test strip that is stable to storage and accelerated keeping test conditions. A sample of a fluid containing an unknown quantity of a predetermined substance is contacted with a support having thereon a reagent layer wherein the reagent layer contains a dialyzed latex polymer and a reagent detection system which reacts with the substance to provide a detectable change. The detectable change can be determined qualitatively or quantitatively to determine the presence or the amount of the predetermined substance.
Claims8
A method for the detection of a predetermined substance in a fluid, the method comprising:
- contacting a sample of a fluid containing an unknown quantity of the predetermined substance with a support having thereon a reagent layer wherein the reagent layer contains a dialyzed non-particulate latex polymer and dispersed therein a reagent detection system which reacts with the substance to provide a detectable change;
- and detecting whether a reaction occurred;
- wherein the dialyzed latex polymer constitutes at least about 60% by weight of the dry reagent layer.
A method for the detection of glucose in a fluid, said method comprising:
- providing a transparent support having thereon a reagent layer comprising dialyzed non-particulate carboxylated vinylacetate/ethylene copolymer, glucose oxidase, peroxidase, and a color indicator that changes color when exposed to glucose;
- wherein the dialyzed copolymer constitutes at least 60% by weight of the dry reagent layer;
- contacting a sample of the fluid with the support;
- and
- determining whether any change in color has occurred.
