Description

Technical field: [0001] The invention relates to a high-sensitivity optical detection device, which is especially suitable for quantitative analysis in medical immunological detection. Background technique: [0002] Currently, there are two main types of techniques used in clinical immunoassays: radioimmunoassay (RIA) and enzyme-linked immunoassay (EIA). Advantages of RIA: high sensitivity, good accuracy and repeatability, and can be used for ultra-trace quantitative analysis. The disadvantages are: it can only be applied in large hospitals, and it is difficult to spread to grassroots medical institutions; the radioactive isotope r-rays cause radiation damage to the human body; the detection waste causes radioactive pollution to the environment; the shelf life is short, only one month. EIA is easy to operate and easy to popularize. However, the sensitivity is poor, the repeatability and accuracy are not good, and it is mainly used for qualitative analysis, which is difficu...

AI Technical Summary

Problems solved by technology

The disadvantages are: it can only be applied in large hospitals, and it is difficult to spread to grassroots medical institutions; the radioactive isotope r-rays cause radiation damage to the human body; the detection waste causes radioactive pollution to the environment; the shelf life is short, only one month

However, the sensitivity is poor, the repeatability and accuracy are not good, and it is mainly used for qualitative analysis, which is difficult for quantitative analysis; most of the substrates of enzyme label technology are toxic or carcinogens, and cannot be stored, and must be freshly prepared when used; enzyme label itself Also unstable, susceptible to changes in temperature and pH

Therefore, the current problems in clinical immunoassays are: RIA with high sensitivity, accuracy and repeatability cannot be popularized, and EIA, which is easy to popularize and easy to operate, cannot meet clinical requirements

The vast majority of demand units are unable to afford the expensive instrument prices, and can only look at CLIA's high technology.

[0008] At present, semi-automatic chemiluminescence immunoassay instruments that avoid complex and expensive sample integrated processing systems and integrate machinery, control, software, and low-light detection technology are still blank in the market.
