Application of Dynamic Linear Detecting Method in Data Processing of the Portable Blood Sugar Analyzer

摘要

In this paper, a dynamic linear detecting method, that the non-linear coefficient NL% was led and the non-linearity of data were estimated continuously and dynamically and determined when NL% exceeded reference value (5%), was used for data processing and could solve the problem caused by the phenomenon of substrate depleting occurred following the redox reaction in portable blood sugar analyzer. By contrast to the conventional end-point method, the dynamic linear detecting method is based on multipoint data collecting. Experiments of measuring the calibration glucose solution with 8 various concentrations from 50 mg/dl to 400 mg/dl were carried out with the analyzer developed by our group. The linear regression curve, whose correlation for the data was 0.9995 and the residual was 2.8080, were obtained. The obtained correlation, residual, and the computation workload are all fit for the portable blood sugar analyzer.
