Abstract

There is provided an automatic analyzer that is capable of highly accurately detecting an abnormality at the time of aspiration even though the amount of a sample used for analysis is small. An automatic analyzer according to the present invention includes: a dispensing unit that aspirates a sample from a sample vessel that houses the sample; a control unit that controls the dispensing unit such that the dispensing unit aspirates the sample in a third predetermined amount greater than a first predetermined amount that is an amount of the sample used for analysis, the dispensing unit discharges the sample in a second predetermined amount to a predetermined site different from the sample vessel, and the dispensing unit discharges the sample in the first predetermined amount to a reaction vessel used for analysis; a detection unit that detects a pressure waveform in the dispensing unit; and a determining unit that determines faulty aspiration and/or clogging, based on a first waveform that is the pressure waveform when the dispensing unit aspirates the sample, the faulty aspiration being in a state in which the dispensing unit insufficiently aspirates the sample, the clogging being a state in which the sample is clogged in the dispensing unit.
