Abstract
A biological microparticle inspection apparatus has a reactor in which blood containing T cells is mixed with latex-labeled antibodies and T cells are coupled with the antibodies to form complexes. A particle size measurement unit is provided for measuring the size of the particles contained in the blood, including the complexes. A signal processing unit processes the measured sizes of the particles outputting signals only when the measured sizes fall within a range of the size of the complex, and counts the number of the output signals. The number of the output signals corresponds to the number of the complexes and hence the T cells.
