A test system for measuring the concentration of an analyte in a biological fluid sample comprises: a plurality of test members () in a container (), each test member () including reagent means for indicating the catalytic activity of an enzyme when in the presence of a biological fluid containing an analyte acted upon by the enzyme; 0 a test meter () for receiving a test member (), the meter () having circuitry for performing a measurement on a test member received therein to produce a measured physical value, means for determining an analyte concentration value for a specified biological fluid from said measured physical value, and means () for indicating a determined analyte concentration value; a Container RFID tag () associated with the container () which includes data specific to said plurality of test members (); and a Patient RFID tag () which includes data specific to a patient; and wherein said test meter () includes means for reading and storing data from said Container RFID tag () and from said Patient RFID tag ().

Test system

A test system for measuring analyte concentration in a fluid sample includes:

A non-mediated enzyme electrode comprises a base substrate () on which is provided an electrically conductive base layer () comprising finely divided platinum group metal or oxide bonded together by a resin; a top layer on the base layer (), the top layer comprising a buffer. A catalytically active quantity of an oxidoreductase enzyme is provided in at least one of the base layer and the top layer. The invention also provides a biosensor () which includes an enzyme electrode, and methods of manufacturing the enzyme electrode and biosensor.
