Abstract
A disposable electrochemical sensor for the detection of an analyte such as glucose in a liquid sample is provided. The sensor has a working electrode and a reference electrode disposed within a sample-receiving cavity, and a reagent layer disposed within the sample-receiving cavity and over the working electrode. The reagent layer contains at least an enzyme for producing an electrochemical signal in the presence of the analyte. The sample-receiving cavity has a volume of less than 1.5 .mu.l, and the sensor provides a stable reading of the amount of analyte in a period of 10 seconds or less. Where appropriate for the generation of electrochemical signal, for example in the case of glucose detection, the reagent layer also contains a mediator. The sensor is used in combination with a meter for detection of the analyte in a liquid sample. A suitable meter has a timing circuit for controlling the measurement of current indicative of analyte in the sample following detection of sample application to a test strip inserted in the meter, wherein the timing circuit causes the measurement of current to occur at a time 10 seconds or less after the detection of sample application.
