PURPOSE:To make an accurate decision on the border of a normalcy range by taking plural tests of one objective body and providing a conditional nromalcy range for every normalcy range, and taking a measurement again when test data enters the range and deciding whether the body is normal or not. CONSTITUTION:When factors (a)-(d) are taken as to plural measurement items, e.g. A, B, and C, normalcy ranges 1 of the factors (a)-(d) and conditional normalcy ranges 3 near th border are determined as to the item A; and the overlap range of the ranges 1 is determined as a total normalcy range 2 and the overlap range of the ranges 3 is determined as a total conditional normalcy range 4. Then, ranges 3 and 4 are determined similarly as to the items B and C; it is decided that the tested body is normal when data on the items A-C are all within the range in the 1st measurement, and measuements are taken again as to an item for decision making when there is the item in the range 4. |
