PURPOSE:To measure plural components in a sample liquid at one time by using one sample by color coding each of plural solid carriers according to measuring items, and bonding separate antigens or antibodies corresponding to the measuring items to the respective carriers of each color. CONSTITUTION:A sample to be measured is a sample contg. >=2 kinds of optional components which are previously measured by immunoassay. When an explanation is made by taking an example of a sandwich method, a specified amt. of the sample contg. the plural components to be measured is added to a reaction vessel and is caused to react for a specified time. The carriers are washed in some case after the reaction and thereafter a marked antibody or antigen is added and the sample is further caused to react. The carriers of respective colors are then separately drawn from the sample and the amt. of the marking agents bonded therewith are detected, by which the amts. of the measuring components for the respective carriers are known by one time of measuring operation. The material of the solid carriers may be any material like plastics such as polystyrene, and polycarbonate, cellulose, etc. The color coding of the carriers is accomplished preferably by adding coloring matters such as dyes and pigments to the materials of the respective carriers or color coding suitably the surfaces of the carriers with coloring materials, etc. |
