Abstract

Provided is an automatic analyzer capable of accurately detecting an abnormality during aspiration even when an amount of a reagent used for analysis is small. An automatic analyzer includes: a dispensing mechanism configured to dispense a reagent from a reagent container to a reaction container; a control unit configured to control the dispensing mechanism to aspirate an amount of the reagent used for analysis, the amount including at least a second predetermined amount in addition to a first predetermined amount, then discharge the second predetermined amount of the reagent to the reagent container, and then discharge the first predetermined amount of the reagent to the reaction container; and a pressure sensor configured to measure pressure in the dispensing mechanism. The control unit determines whether the reagent is normally aspirated based on a measurement value of the pressure sensor when the dispensing mechanism aspirates the reagent. When the first predetermined amount is equal to or larger than a first predetermined amount threshold value that is predetermined in advance, the second predetermined amount is a constant value regardless of the first predetermined amount. When the first predetermined amount is smaller than the first predetermined amount threshold value, the second predetermined amount is larger than the constant value.
