A main controller of an immunological test apparatus counts an elapsed time TP. An information output unit outputs required determination time information regarding a required determination time so as to be associated with information of a determination result. The required determination time information is at least information indicating that the elapsed time TP exceeds a set time TS at which sensitization processing, in which a chemical solution for sensitizing the coloration state of a reagent that is combined with influenza virus to be colored is spread onto a carrier, is started, that is, information indicating that the sensitization processing has been performed.
