| 摘要 |
The present invention relates to a simple immunochemical semi-quantitative assay method according to chromatography, which comprises trapping a certain amount of an analyte in a sample with a predetermined amount of a fixed antibody for the analyte before qualitative analysis of the analyte, the certain amount corresponding to the amount of the fixed antibody, and thereby decreasing a concentration of the analyte to be subjected to subsequent immunochemical qualitative determination, and an apparatus therefor.
