AI Technical Summary

Problems solved by technology

Due to the existence of the HD-HOOK effect, the detected samples cannot be correctly distinguished because their concentration exceeds the linear range of the detection kit or the concentration itself is the value, so that the experiment is misdiagnosed, especially resulting in an increase in the false negative rate

Embodiment Construction

[0051] The present invention will be further described below in conjunction with accompanying drawing.

[0052] In one embodiment of the invention, the immunoassay device comprises:

[0053] Readout unit for recording the chemiluminescent reaction and taking multiple readings of the incubated mixture;

[0054] A processing unit connected to the reading unit, the processing unit judges whether there is a Hook risk in the immunoassay according to the reading of the reading unit.

[0055] In one embodiment, the immunoassay device further includes a moving mechanism for moving the incubated mixed solution to a reading unit for reading;

[0056] In one embodiment, the immunoassay device further comprises an incubator for providing a suitable ambient temperature for the chemiluminescence immunoreaction;

[0057] In one embodiment, the immunoassay device further includes a reset mechanism, which is used to reset the mixed solution after reading to the incubator for re-incubation; ...

Abstract

The invention relates to an immunoassay device which comprises a reading unit and a processing unit, wherein the reading unit is used for recording a chemiluminescence reaction and performing readingon incubated mixed liquid for many times; and the processing unit is connected with the reading unit and judges whether immunoassay has a Hook risk according to a reading of the reading unit. The device avoids experimental misdiagnosis since whether a concentration of a detected sample exceeds a linear range of a detection kit or the concentration is the value cannot be differentiated correctly due to a Hook effect.

Description

technical field [0001] The invention relates to the technical field of chemiluminescence immunoassay, in particular to an immunoassay device. Background technique [0002] 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. [0003] Chemiluminescent immunoassay is a non-radioactive immunoassay technology that has developed rapidly in recent years. Its principle is to use chemiluminescent substances to amplify the signal, and use its luminous intensity to directly measure the immune binding process. This method has become an immunological method. One of the important directions of detection. [0004] The double-antibody sandwich method is a method commonly used by chemiluminescence analysis technicians. The conventio...
