Patent ID: 8741218

Claim:
An automatic analyzer comprising: a reaction vessel to contain a reaction solution including antigens and antibodies for an antigen-antibody reaction, where luminescent labels are bonded to one of the antigens, the antibodies or another substance in the reaction solution directly or indirectly, the reaction vessel includes a portion which collects carriers formed with antigen-antibody bonding present in the reaction solution from the antigen-antibody reaction, the carriers including the luminescent labels; a measuring mechanism to detect light generated from the carriers collected on the portion of the reaction vessel; and a moving mechanism to move the reaction vessel to a measurement position and the portion of the reaction vessel which has collected the carriers formed with the antigen-antibody bonding are separated from a remainder of the reaction solution so that the measuring mechanism detects the light from the portion of the reaction vessel, wherein the moving mechanism moves the reaction vessel to the measurement position a plurality of times after starting the antigen-antibody reaction so that the measuring mechanism quantitatively measures the antigen-antibody reaction in time series, and wherein the concentration of carriers collected at the portion of the reaction vessel changes over the time series.
