Field immunoassay reaction system, method of immunoassay diagnosis and probe or carrier for use therewith.

摘要

A field immunoassay reaction system and method is provided. The reaction system comprises the following components: i) a dipstick carrier or probe at least partly coated with monoclonal antibody specific for an antigen contained in a body substance or fluid; (ii) a plurality of containers; (iii) detergent or other suitable substance to prevent non-specific binding of antigen to the monoclonal antibody; (iv) buffer; and (v) in situ signal amplification or detection means. Preferably there is also included as an additional component a second monoclonal antibody labelled with an enzyme and enzyme substrate. The detection means is suitably a colour standard or portable colourimeter.
