Abstract: An automatic analysis apparatus is capable of stirring a reagent without reducing the analysis processing capacity. The automatic analysis apparatus includes a reagent table that is rotatable and that holds reagent vessels, and a plurality of magnets are disposed below the reagent table, with orientations of magnetic poles of the magnets fixed, along a movement path of the reagent vessels moving on a circumference when the reagent table is rotationally driven. The plurality of magnets is disposed such that the fixed orientations of the magnetic poles of the magnets vary along the movement path, and act a magnetic force on a stirring bar in each of the reagent vessels. When the reagent table is rotated and the reagent vessels pass above the magnets, the stirring bar in each of the reagent vessels is rotated or oscillated by the magnetic force received from the magnets, to stir the reagent.

Abstract: Provided is a method for measuring a substance in a blood sample, which allows avoidance of the influences of both of bilirubin and hemoglobin by simple operations. Provided is a method for measuring a substance in a blood sample by an enzymatic method using an oxidizable color reagent, the method including (1) bringing the blood sample into contact with a non-ionic surfactant; and then (2) bringing the resultant sample into contact with a betaine-type amphoteric surfactant, to perform an enzyme reaction and a color reaction by an oxidizable color reagent at the same time as the contact or after the contact.
