An immunoassay based on the agglutination or the agglutination inhibition of a suspension of immunologically coated particles by the sample. Measurements are made with an apparatus having means for providing electromagnetic radiation at wavelengths equal to or less than the mean diameter of the particles and in a range of at least about 100 nm. The apparatus also includes means for measuring, at a predetermined angle, a portion of the radiation transmitted through a cuvette containing the reaction mixture.
