摘要： A method of determining analyte concentration uses a redox reaction in an electrochemical cell that has at least two electrodes, one of which is a working electrode, at least one electrode being exposed to at least one redox mediator. The method uses at least one cycle of pulses, each cycle having at least a first potential and a second potential. The method comprises applying a first potential to initiate an accumulation phase that forces accumulation of a mediator concentration gradient at or close to the working electrode with a concentration that decreases towards the bulk solution, applying a second potential to initiate a measurement phase and deplete the established mediator concentration gradient at the working electrode, measuring current associated with the second potential of each cycle, and using the measured current to determine analyte concentration. In this way, the effects of diffusion interfering factors (DIF), especially haematocrit (Hct) can be mitigated.

摘要： A test sensor (100) for determining an analyte concentration in a biological fluid comprises a strip including a fluid receiving area (128) and a port-insertion region (126). A first row of optically transparent (132) and non-transparent positions forms a calibration code pattern (130) disposed within a first area of the port-insertion region (126). A second row of optically transparent (142) and non-transparent positions forms a synchronization code pattern (140) disposed within a second area of the port-insertion region (126). The second area is different from the first area. The synchronization code pattern (140) corresponds to the calibration code pattern (130) such that the synchronization code pattern (140) provides synchronization of the serial calibration code pattern (130) during insertion of the port- insertion region (126) into the receiving port of the analyte meter.

摘要： A system for determining usability of an analytical test strip having two electrodes connected in series with a sample cell includes a test meter configured to receive the test strip. The sample cell receives a fluid sample, the sample cell with the received fluid sample having a frequency-dependent impedance. A microprocessor and circuit in the test meter cause application of an AC waveform across the sample cell via the electrodes upon detection of sample in the sample cell and concurrently measure of a current through the electrodes. The AC waveform has a frequency at which the characteristic impedance is substantially zero. The measured current is inversely proportional to a series resistance of the two electrodes. A hand-held test meter and a method for determining usability of an analytical test strip are also described.
