    Abstract: A multiple-layer element method for monitoring the concentration of glucose in blood. The element comprises: (a) a core layer having two major surfaces, an optical reading chamber extending from a first opening in one of said two major surfaces to a second opening in the other of said two major surfaces, said, core layer further having a third opening therein and a flow channel, one end of which flow channel communicates with the third opening and the other end of which flow channel communicates with the optical reading chamber; and (b) a base layer in face-to-face contact with one major surface of said core layer; and (c) a cover layer in face-to-face contact with the other major surface of said core layer, said cover layer having an opening therein to vent the element. The method involves (a) obtaining a sample of biological fluid, e.g., interstitial fluid, from the body of a patient; (b) introducing the sample to article comprising a multiple-layer element having an optical reading chamber; (c) allowing reagents to react with an analyse of interest in the sample; and (d) measuring the concentration of analyse in the sample by means of an optical instrument.

    Abstract: This invention presents novel separation and assay procedures which allows both the indicator and the capture reagents to be in solution to avoid problems of slowed immunoreaction kinetics. The separation procedure involves an analyte-specific soluble capture reagent, that is conjugated to a charged substance, and an insoluble solid phase material that is oppositely charged. A fluid sample suspected of containing the analyte is mixed with the capture reagent in solution to form a charged capture reagent/analyte complex. When binding is complete, the solution is contacted to the oppositely charged solid phase material to attract, attach, and separate the capture reagent/analyte complex from the fluid sample. With the appropriate indicator reagent, i.e., a second analyte-specific binding substance which is conjugated to a label capable of producing a detectable signal, both sandwich and competitive assays can be performed. The assay reaction complex can be separated from the solution by contact with the oppositely charged solid phase material, and the presence or amount of analyte is monitored by detecting the label of the indicator reagent.
