Claim:
1. A biological sample analyzing apparatus comprising: an assay sample preparation unit comprising a mixing container and a dispenser operable to aspirate a testing reagent, which contains carrier particles with a substance for causing an antigen-antibody reaction, and a biological sample, which is selected from a group consisting of blood, urine, whole blood, plasma and serum and contains an assay material reactive with the substance through the antigen-antibody reaction, in the mixing container to prepare an assay sample in which some of the carrier particles are agglutinated by the assay material reacted with the substance and a reminder of the carrier particles are not agglutinated; a measuring unit comprising a flow cell through which the assay sample including the agglutinated carrier particles and the unagglutinated particles is flown, and a laser light source operable to irradiate a laser light to the agglutinated and unagglutinated carrier particles in the assay sample flowing through the flow cell, the measuring unit further comprising a light detector configured to detect a light scattered from the agglutinated and unagglutinated carrier particles in the assay sample flowing through the flow cell, wherein the scattered light carries size information indicative of a size of a respective one of the agglutinated and unagglutinated carrier particles in the assay sample, and the agglutinated and unagglutinated carrier particles in the assay sample are distinguishable from each other by the size information; a display device; and a controller computer programmed to perform operations comprising:
