Abstract:
1. A sensor for receiving, storing, and chemically reacting with fluid samples from a user for purposes of detecting and quantifying the amount of analytes in such samples by optical means using an optical measurement instrument, such a sensor comprising: a base support member, such a base support member providing support for said sensor and having an aperture that allows a portion of a reaction membrane to be exposed to said optical measurement instrument; said reaction membrane having a surface which is in physical contact with said base support member and covers all of said aperture, said reaction membrane comprising at least one reagent for reacting with at least one compositional component of said analytes and requiring no redox mediators for reaction; a storage chamber comprising an open-ended capillary passage for conducting said sample from an incision laterally across the width of said storage chamber and simultaneously permitting said sample to saturate said reaction membrane without an additional sorbent material, wherein: whereby said sensor is used to measure the amount of analytes in such fluid samples without the use of electrodes on said sensor.
