  • Patent number: 11733198
    Abstract: A method for determining a concentration of an analyte in a fluidic sample is described. A sample is applied to a biosensor including an electrochemical cell having electrodes. A predetermined voltage waveform is applied during at least first and second time intervals. At least first and second current values are measured during the first and second time intervals, respectively. A turning point time is determined during the first time interval at which the measured first current values transition from a first to a second profile. The concentration of analyte in the sample is calculated based on determined turning point time and at least one measured current value. In another example, a physical characteristic of the sample is estimated based on measured current values. The concentration is calculated using a first or second model if the estimated physical characteristic of the sample is in a first or second range, respectively.

  • Publication number: 20150241378
    Abstract: An electrochemical-based analytical test strip (“TS”) for the determination of an analyte in a bodily fluid sample includes an electrically insulating substrate, a patterned conductor layer disposed over the electrically-insulating substrate and having an analyte working electrode (“WE”), a bare interferent electrode (“IE”) and a shared counter/reference electrode (“CE”). The TS also includes a patterned insulation layer (“PIL”) with an electrode exposure slot configured to expose the WE, IE and CE, an enzymatic reagent layer disposed on the WE and CE, and a patterned spacer layer (“PSL”). The PIL and the PSL define a sample receiving chamber with a sample-receiving opening. The IE and the CE constitute a first electrode pair configured for measurement of an interferent electrochemical response and the WE and the CE constitute a second electrode pair configured for measurement of an analyte electrochemical response. The WE and the IE are electrically isolated from one another.
