ACCURATE ANALYTE MEASUREMENTS FOR ELECTROCHEMICAL TEST STRIP BASED ON MULTIPLE CALIBRATION PARAMETERS

摘要

Various embodiments for systems and methods that allow for a more accurate analyte concentration with a biosensor by obtaining two calibration codes, one for batch calibration due to manufacturing variations and the other for time calibration due to measured physical characteristics of the fluid sample.

1. A glucose measurement system comprising:
a biosensor having at least one electrode configured to receive an input signal that initiates an electrochemical reaction between a fluid sample and enzyme disposed on the at least one electrode; and a processor connected to a memory and a power supply to drive at least one input signal to the at least one electrode of the biosensor, the processor configured to obtain a batch calibration code and a timing calibration code so that the processor determines, based on the timing calibration code, a particular time from a start of test measurement sequence at which to measure output signals from the sample and ascertains an analyte amount in the fluid sample from the output signals measured at the particular time and the batch calibration code.
