ABSTRACT:
In a method of assay for a trace component such as antigen, antibody or enzyme utilizing immunochemical reaction or enzyme reaction in combination with photographic detection system comprising measuring optical density of a silver image formed in proportion to the antigen, antibody or enzyme to be measured, a novel analysis sheet comprising a support having provided thereon, in succession, a water absorbing layer and a silver halide emulsion layer is employed. The analysis sheet essentially increases the amount of water absorbed so that the analysis sheet is extremely effective for improving detection sensitivity.
