Patent number: 10371663Abstract: Methods for determining a concentration of an analyte in a sample, and the devices and systems used in conjunction with the same, are provided herein. In one exemplary embodiment of a method for determining a concentration of an analyte in a sample, a sample including an analyte is provided in a sample analyzing device having a working and a counter electrode. An electric potential is applied between the electrodes and a first analyte concentration is determined. A second analyte concentration value is calculated from the first analyte concentration value and corrected for temperature effects, fill time and capacitance to provide for a final analyte concentration value.Type: GrantFiled: March 13, 2017Date of Patent: August 6, 2019Assignee: LIFESCAN IP HOLDINGS, LLCInventors: Ronald C.

Patent number: 10151724Abstract: Methods for distinguishing between an aqueous non-blood sample (e.g., a control solution) and a blood sample are provided herein. In one aspect, the method includes using a test strip in which multiple current transients are measured by a meter electrically connected to an electrochemical test strip. The current transients are used to determine if a sample is a blood sample or an aqueous non-blood sample based on characteristics of the sample (e.g., amount of interferent present, reaction kinetics, and/or capacitance). The method can also include calculating a discrimination criteria based upon these characteristics. Various aspects of a system for distinguishing between a blood sample and an aqueous non-blood sample are also provided herein.Type: GrantFiled: November 22, 2013Date of Patent: December 11, 2018Assignee: LIFESCAN IP HOLDINGS, LLCInventors: Ronald C.

Publication number: 20180195994Abstract: Methods for determining the hematocrit of a blood sample, and devices and systems used in conjunction with the same. The hematocrit value can be determined on its own, and further, it can be further used to determine a concentration of an analyte in a sample. In one exemplary embodiment of a method for determining the hematocrit value in a blood sample, a volume of blood is provided in a sample analyzing device having a working and a counter electrode. An electric potential is applied between the electrodes and an initial fill velocity of the sample into the device is calculated. The hematocrit of the blood, as well as a concentration of an analyte in view of the initial fill velocity can then be determined. Systems and devices that take advantage of the use of an initial fill velocity to determine hematocrit levels and make analyte concentration determinations are also provided.Type: ApplicationFiled: March 9, 2018Publication date: July 12, 2018Inventors: Ronald C.

Patent number: 9784707Abstract: Methods for calculating an analyte concentration of a sample are provided. In one exemplary embodiment the method includes steps that are directed toward accounting for inaccuracies that occur as a result of temperature variations in a sample, a meter, or the surrounding environment. In another exemplary embodiment the method includes steps that are directed toward determining whether an adequate sample is provided in a meter because insufficient samples can result in inaccuracies. The methods that are provided can be incorporated into a variety of mechanisms, but they are primarily directed toward glucose meters for blood samples and toward meters for controls solutions.Type: GrantFiled: September 14, 2012Date of Patent: October 10, 2017Assignee: LifeScan, Inc.Inventors: Alastair M.

Patent number: 9739749Abstract: Methods of determining a corrected analyte concentration in view of some error source are provided herein. The methods can be utilized for the determination of various analytes and/or various sources of error. In one example, the method can be configured to determine a corrected glucose concentration in view of an extreme level of hematocrit found within the sample. In other embodiments, methods are provided for identifying various system errors and/or defects. For example, such errors can include partial-fill or double-fill situations, high track resistance, and/or sample leakage. Systems are also provided for determining a corrected analyte concentration and/or detecting some system error.Type: GrantFiled: December 19, 2014Date of Patent: August 22, 2017Assignee: LifeScan, Inc.Inventors: Ronald C.
