An apparatus for assaying an antigen or antibody

摘要

The invention provides a method of assaying an antigen or antibody in a sample by bringing the antigen- or antibody-containing sample into contact with a support for agglutination reaction as sensitized with an antibody or antigen respectively corresponding to the antigen or antibody in said sample and determining the quantity of the resulting agglutinate precepitate, which comprises measuring the diameter of the precipitate by means of a one-dimensional image sensor capable of sensing, on a line passing the center of said agglutinate precipitate, the intensity of the light from a light source after its passage through the agglutinate precipitate, and an apparatus for assaying an antigen or antibody in a sample by the above method.
