摘要: A multi-use assay system accurately docks a removable test strip supporting a reagent-analyte reaction with an optics system including an LED, photodetector, and lenses or light pipes for directing light to and from the test strip. Docking is achieved using alignment fixturing, whereby an optics block holder is relied upon to align the test strip and test pad with the various optical components. Signals from the photodetector indicative of test strip reaction progress are provided to a processor for measuring the analyte.

摘要: A strip for testing for the presence of an analyte generally comprises a support member which contains a spreading layer and a reagent layer, and a capillary tube in communication with the support layer and spreading layer for transporting a sample of body fluid thereto. A method of testing a fluid for the presence or concentration of an analyte is also provided which generally includes providing a test strip with a support member, a spreading layer, and a reagent layer on the spreading layer. A capillary tube is provided on the support member whereby a fluid containing an analyte to be tested is introduced into the tube and flows through the tube to the spreading layer and contacts the reagent layer.

摘要: An electrochemical test device is provided for determining the presence or concentration of an analyte in an aqueous fluid sample. The electrochemical test device includes a working electrode and a counter electrode made of an amorphous semiconductor material. The working electrode is overlaid with a reagent capable of reacting with an analyte to produce a measurable change in potential which can be correlated to the concentration of the analyte in the fluid sample. The test device optionally contains a reference electrode made of an amorphous semiconductor material having a reference material on the reference electrode.
