An analysis device AN includes determination means 6, capable of performing a first determination on whether a specific component in urine is positive or negative, on the basis of a color reaction between a reagent and the specific component in urine; and optical measurement means 7B capable of working out data on light absorption characteristics of the urine itself with respect to light of a predefined wavelength region. When the data on the light absorption characteristics lies within a predefined range, and a result of the first determination is either positive or negative as established beforehand, the determination means 6 changes the result of the first determination to a false positive or a false negative, or performs second determination to the effect that there is a likelihood of a false positive or a false negative. As a result, it becomes possible to determine accurately whether a component in urine, if any, yields a false positive or false negative, or to determine that there is a likelihood of such an occurrence. A highly reliable testing result can be achieved thereby. |
