摘要:
An analytical test strip for the determination of an analyte (such as glucose and/or hematocrit) in a bodily fluid sample (such as a whole blood sample) includes a first capillary sample-receiving chamber, a second capillary sample-receiving chamber, and a physical barrier island disposed between the first and second capillary sample-receiving chambers. Moreover, the physical island barrier is disposed such that bodily fluid sample flow between the first capillary sample-receiving chamber and the second capillary sample-receiving chamber is prevented during use of the analytical test strip.

An electrochemical-based analytical test strip for the determination of an analyte (such as glucose) in a bodily fluid sample (for example, a whole blood sample) and/or a characteristic of the bodily fluid sample (for example, hematocrit) includes a first sample-receiving chamber with first and second sample-application openings, and first and second electrodes. The first and second electrodes are disposed in the first sample-receiving chamber between the first and second sample-application openings. The electrochemical-based analytical test strip also includes a second sample-receiving chamber and a plurality of electrodes disposed in the second sample-receiving chamber. In addition, the second sample-receiving chamber intersects the first sample-receiving chamber between the first and second electrodes, thereby defining a chamber intersection.

Described and illustrated herein are systems and exemplary methods of operating a multianalyte measurement system having a meter and a test strip. In one embodiment, the method may be achieved by applying a test voltage between a reference electrode and a first working electrode; measuring a first test current, a second test current and a third test current at the working electrode with the meter after a blood sample containing an analyte is applied to the test strip; estimating a hematocrit-corrected analyte concentration from the first, second and third test currents; and displaying the hematocrit-corrected analyte concentration.

A wound dressing (10) including a plurality of discrete, spaced apart pairs of electrodes (18a, 18b) for allowing an electrical property or characteristic of the dressing (10) to be measured. By measuring an electrical characteristic of the dressing, such as the impedance, the hydration thereof can be determined and monitored.

摘要:
An analytical test strip (“ATS”) for use with a hand-held test meter in the determination of an analyte in a bodily fluid sample includes an electrically insulting substrate, a first patterned conductor layer disposed on the electrically insulating substrate and having a working electrode and a reference electrode. The ATS also includes an enzymatic reagent layer disposed on the working electrode, a first patterned spacer layer disposed over the first patterned conductor layer and defining both a first sample-receiving channel and an analyte determination sample chamber within the ATS, and a second patterned spacer layer disposed over the first patterned spacer layer and defining at least a second sample-receiving channel. The ATS further includes a bodily fluid phase-shift sample chamber in fluidic communication with the second sample-receiving channel. The first sample-receiving channel and analyte determination sample chamber are isolated from the second sample-receiving channel and bodily fluid phase-shift sample chamber.

Described and illustrated herein are systems and exemplary methods of operating an analyte measurement system having a meter and a test strip. The methods and systems describe herein allow for trapping various errors during calculation of the analyte due to variations in the structure and materials making up the test strip and ambient temperatures.
