Provided is an automatic analyzer having an information leakage prevention function for managing viewing of specimen information by a user. For this purpose, when a logged-in user causes a display device to display specimen information on a predetermined specimen ID, a computer refers to reference authority information set for each analysis item regarding a user ID of the user and reference classification information in specimen ID data on the predetermined specimen ID, and determines whether a measurement value of an analysis item can be displayed. For example, a measurement value of an analysis item requested for the predetermined specimen ID is hidden on the display device when reference classification information on the analysis item is a classification indicating presence of a reference restriction in the specimen ID data and reference authority information set for the analysis item regarding the user ID is a classification indicating absence of a reference authority.
