20110284393 | ANALYTICAL TEST STRIP WITH AN ELECTRODE HAVING ELECTROCHEMICALLY ACTIVE AND INERT AREAS OF A PREDETERMINED SIZE AND DISTRIBUTION - An electrochemical-based analytical test strip for the determination of an analyte (e.g., glucose) in a bodily fluid sample (such as a whole blood sample) includes an electrically insulating base layer and a patterned conductor layer (for example, a gold patterned conductor layer) disposed over the electrically-insulating layer. The patterned conductor layer includes at least one electrode with the electrode having electrochemically inert areas and an electrochemically active area(s). Moreover, the electrochemically inert areas and electrochemically active area(s) are of a predetermined size and a predetermined distribution such that electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response. | 11-24-2011 |

20130047415 | USE OF CHAMBER HEIGHT TO AFFECT CALIBRATION CODE IN TEST STRIP MANUFACTURING - The invention provides a method for varying the intercept of a batch of test strips by varying the height of the strip's sample-receiving chamber. | 02-28-2013 |
20130084591 | ANALYTICAL TEST STRIP WITH ISOLATED BODILY FLUID PHASE-SHIFT AND ANALYTE DETERMINATION SAMPLE CHAMBERS - 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. | 04-04-2013 |
20140251833 | METHODS AND SYSTEMS TO DETERMINE FILL DIRECTION AND FILL ERROR IN ANALYTE MEASUREMENTS - Various embodiments for methods and systems that allow for detecting of a direction in which a sample is flowing towards a plurality of electrodes and detecting a fill error of an electrochemical test strip. | 09-11-2014 |
20150362454 | ANALYTICAL TEST STRIP WITH CAPILLARY SAMPLE-RECEIVING CHAMBERS SEPARATED BY A PHYSICAL BARRIER ISLAND - 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. | 12-17-2015 |
20150369769 | END-FILL ELECTROCHEMICAL-BASED ANALYTICAL TEST STRIP WITH PERPENDICULAR INTERSECTING SAMPLE-RECEIVING CHAMBERS - 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 (e.g., hematocrit) includes a sample-entry chamber with a sample-application opening disposed on an end edge of the electrochemical-based analytical test strip, and first and second sample-determination chambers, each in direct fluidic communication with the sample-entry chamber. The electrochemical-based analytical test strip also includes first and second electrodes (such as first and second hematocrit electrodes) disposed in the first sample-determination chamber, and a third and fourth electrodes (for example working and reference electrodes) disposed in the second sample-determination chamber. Moreover, the first and second sample-determination chambers intersect the sample-entry chamber perpendicular (or nearly perpendicular) to one another and the first sample-determination chamber also intersects the sample-entry chamber in an aligned manner. | 12-24-2015 |
