Abstract

On each particular field, latter half and each institute in 1990's proposed reference value simultaneously. Until now, “normal value”has been used for the case of the medical judgment. The concept with the normal can not have the distrust, while it is long, either, and it keeps be used the thing that the result which there is in the normal counter electrode is abnormal and that it is not abnormal. However, the advance of science and technology had made more detailed analysis and diagnosis to be a possible thing, and in being not a disease as a concept of the health only, it became the age which did not become an evaluation of the health. Only that measuring method increases also increases on“reference value”... and, the compatibility between facilities becomes also a difficult situation, as measuring method increases. It looks forward to the medical examinee easily comparing with test result by last time, even if it has in when, where medical examination. Body information for the medical examination traces the wholeheartedness of miniaturization and segmentation, and diagnosis information increases by a diversity more precisely. The medical examination facilities would have to have the technique for making type of the reference value which increases like this and compatibility between facilities to be an easy thing. There is the trial which intends to unify the reference value adopted in each facilities, and it worries with whether that the specificity in which measuring method and measurement have the reference value which is a medical criterion is unified by disregarding, does not hurt the accuracy of the diagnosis. Then, the reference value adopted between facilities proposed common evaluation method in which becoming common, was possible by standardizing measured value by each reference value, while it is used in the convention way.“Common evaluation method”was proposed as the result which measuring method and reference value which are segmented also examined the possibility of the forecast prediction of health risk of reference value of the group and individual reference value by the comparison, while it is used in the pair along the convention as a criterion.
