When a plural number of subjects to be tested are continuously and sequentially measured, and the values obtained by measurement are compared with a standard value for judgement, a prescribed number of newly inputted measured values are sequentially stored, a mean value is computed basing upon stored values for determining the standard value for judgement, and the measured values are compared with the standard value for judgement for judging whether these measured values are to be employed or not. Whenever new measured values are inputted, a new standard value is determined. If there is a value for an inferior subject among newly inputted measured values, the value is omitted from computation of the standard value for judgement.
