Analyte Determination Method and Analyte Meter

摘要

The presence of oxygen or red blood cells in a sample applied to an electrochemical test strip that makes use of a reduced mediator is corrected for by an additive correction factor that is determined as a function of the temperature of the sample and a measurement that reflects the oxygen carrying capacity of the sample. The measured oxygen carrying capacity can also be used to determine hematocrit and to distinguish between blood samples and control solutions applied to a test strip.

主权项

1. A method for determining an analyte in a sample comprising the steps of:
(a) placing the sample in an electrochemical test cell comprising a working and a counter electrode and a mediator that serves as a charge carrier in the electrochemical determination of the analyte, (b) electrochemically determining an uncorrected result for the determination of analyte in the sample; (c) determining an additive correction term for the amount of oxygen in the sample, and (d) modifying the uncorrected result of step (b) by adding the additive correction term of step (c) to provide a corrected determination of analyte in the sample, wherein the additive correction term for the amount of oxygen in the sample is determined as a function of the temperature of the sample and a measurement that reflects the oxygen carrying capacity of the sample.
