Abstract

The invention relates to an immunoassay method in the technical field of light initiated chemiluminescence. The immunoassay method comprises the following steps: (1) carrying out chemiluminescence immunoreaction on a to-be-measured sample which contains a to-be-measured target antigen (or antibody), stimulating and recording first-time reading and second-time reading of chemiluminescence, and recording amplification of difference between the second-time reading and the first-time reading as A; (2) taking the amplification A of the two-time readings of a known standard substance which containsthe to-be-measured target antigen (or antibody) as a critical value; and (3) comparing the amplification A of the two-time readings of the to-be-measured sample which contains the to-be-measured target antigen (or antibody) to the critical value, if the amplification A of the two-time readings of the to-be-measured sample which contains the to-be-measured target antigen (or antibody) is greater than the critical value, showing that the concentration of the to-be-measured sample is higher than the concentration of the known standard substance; and meanwhile, if the first-time reading of the to-be-measured sample is lower than the known standard substance, diluting the sample and then measuring the sample.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of November 22, 2016, an application number of 201611026623.1, and an invention title of "immunoassay method, system and kit for identifying immunoassay". technical field [0002] The present invention relates to the technical field of light-activated chemiluminescence, in particular to an immunoassay method, a system for identifying an immunoassay, and a kit; another immunoassay method, another system for identifying an immunoassay system and another kit. Background technique [0003] Immunological detection is based on the principle of antigen-antibody specific reaction. Because it can use isotopes, enzymes, chemiluminescent substances, etc. to display or amplify the signal of the measured substance, it is often used to detect trace organisms such as proteins and hormones. active substance. [0004] Chemiluminescent immunoassay is a non-radioactive immunoassay tech...
