ABSTRACT:
A novel method and a novel apparatus therefor are described for detecting and measuring a predetermined immunochemical substance, for example, an antigen, an antibody, a hapten, or certain low molecular weight substance. The detection and measurement of an immunochemical substance using the method and apparatus of the invention involves providing for the agglutination of a suspension of particles in a sample, or color intensity of solutions by which, using the apparatus of the invention to determine certain electromagnetic radiation properties of the sample, the presence and amount of the immunochemical substance can be determined.
