Abstract
There are provided a method and an apparatus for measuring an immunologically active material by physically or chemically immobilizing a material being immunologically active to a material to be measured of a specimen onto dehydrated solid fine particles, providing a desired dispersed body of said immunologically active material immobilized onto said solid fine particles in a dispersing medium, adding the specimen to said dispersed body while stirring to react the specimen with the immunologically active material, thereby causing a reaction mixture in an agglutinated state and optically measuring said agglutinated state of the reaction mixture to thereby quantitatively determine the content of the material to be measured with an improved accuracy.
