STUDY OF ""LAW OF PROPAGATION OF UNCERTAINTY"" ON THE ISO-GUM – APPLICATION TO THE BLOOD CHEMICAL ANALYSIS

Yasuo Iwaki, Tadao Inamura

Abstract

Generally, analysis of variance (ANOVA) has been using for the data analysis of the measured value. On the other hand, J.W. Tukey had studied the exploratory data analysis (EDA) in 1977. Therefore, the ISO (International organization for standardization) made the ISO-GUM (Guide to the expression of Uncertainty) that is a guidebook adopted EDA in 1993. In the ISO-GUM, the dispersion of data is evaluated as the uncertainty with the error. In the medical field, ISO-GUM was also taken up it. Nowadays, the improvement of accuracy of the measurement data on the blood chemical material analysis (BCA) is done by WHO standard based on ANOVA. ANOVA is said as the classical data analysis as well (CDA). The purpose of this study is to make the improvement of the accuracy in the quality control (QC) of the measured value and to make an accuracy assurance. So, it was verified how it was different when ISO-GUM rule and WHO standard were applied to BCA.
