Working Principle:

Chemi-luminescence immunoassays contain two systems of immunoassay and chemi-luminescence analysis. The immunoassay system uses a chemi-luminescent substance or an enzyme as a label, and directly marks the antigen or the antibody, and reacts with the antibody to form an antigen-antibody immune complex. The chemi-luminescence analysis system is a luminescent substrate in which an oxidizing agent or an enzyme is added after the end of the immune reaction. The chemi-luminescent substance is oxidized by the oxidizing agent to form an intermediate in an excited state, which emits photons to release energy to return to a stable ground state. The luminous intensity can be detected using an illuminating signal measuring instrument. According to the relationship between the chemi-luminescent label and the luminescence intensity, the content of the analyte can be calculated using a standard curve.

Typical structure:

1) Generally for desktop or floor type.

2) According to the degree of automation can be divided into fully automatic and semi-automatic.

: Used in conjunction with blood glucose test strips for quantitative detection of glucose concentrations in human capillary whole blood and/or venous whole blood and/or arterial whole blood (also plasma/serum)

Product Features:

1) There are many types of illuminating, and the available methods and types of luminescent substances are more selective.

2) Whether the marker needs to be separated during the reaction can be divided into homogeneous reaction and heterogeneous reaction.

3) Separation methods can be divided into: solid phase separation, filtration separation, bead separation, paramagnetic particle separation, etc. to achieve separation of free markers and immune complex markers

2. Classification

Classification Code: 22-04-02 Class II Chemi-luminescence immunoassay instrument

Product Description: Usually consists of one or more of a loading module, a reaction module, an optical detection module (photomultiplier tube), a data processing module, an incubation temperature control module, and a cleaning separation module. The principle is generally to convert the optical signal emitted by the chemi-luminescence reaction into a digital signal, and the data processing system calculates the concentration value.

Expected Usage: Used in conjunction with an adaptation reagent for qualitative and/or quantitative analysis of the analyte in a human sample.

3. Registration Unit

In principle, the technical principle, structural composition, performance index and scope of application of the fully-automated chemi-luminescence immunoassay analyzer of the same registered unit should be basically the same. Products with different sample processing quantities due to different number of single functional modules can be used as the same registered unit. A product in a situation should be divided into different registration units:

1) Products of different chemi-luminescent reaction types, such as products based on the principle of direct chemi-luminescence reaction of acridine esters and indirect chemi-luminescence reactions based on AMPPD and alkaline phosphatase, should be classified into different registration units.

2) Products using different methods for separating free markers and immune complex markers should be classified into different registration units.

3) Products using different photodetection devices should be divided into different registration units.

4) The chemi-luminescence reaction type is the same, the separation method of the free label and the immune complex label is the same, and the intended use is basically the same, but the product has a significant influence on the safety effectiveness due to the difference in the main design structure of the product, regardless of the sample processing speed. Whether there are differences in sample processing volume, analytical performance indicators, etc., should be divided into different registration units.

22-04 Automatic immunoassay analyzer

Usually consists of a sampling center, a processing center, a waste liquid and a supply center, a system control center, etc., based on an immunological reaction in which antigen and antibody bind to each other, using an enzyme label or a chemi-luminescent agent to label the antigen and antibody, and through a series of cascade amplification The reaction combines an optical signal or an electrical signal with an analyte concentration or the like to analyze an antigen or antibody to be tested in a human sample. It is used for quantitative, semi-quantitative or qualitative detection of various analytes in human body fluids, such as tumor markers, pathogen antigen antibodies and the like.
