What is Chemiluminescence Immunoassay?
Chemiluminescence Immunoassay (CLIA) is a laboratory technique used to detect and quantify specific substances such as proteins, hormones, and antibodies in biological samples. This method utilizes the emission of light (chemiluminescence) during a chemical reaction, which is then measured to determine the concentration of the analyte in the sample. CLIA is widely used in clinical diagnostics due to its high sensitivity and specificity, making it ideal for detecting low levels of biomarkers in blood or other bodily fluids.
Why CLIA is Important in Medical Diagnostics?
CLIA provides several advantages in medical diagnostics:
- High Sensitivity and Specificity: CLIA offers superior accuracy and reliability, even for detecting very small amounts of target substances.
- Broad Application: This technique is used for various applications including hormone testing, infectious disease detection, and cancer biomarker assays.
- Quick Results: CLIA assays provide fast and efficient results, essential for rapid decision-making in clinical settings.
History of Immunoassay Development
Immunoassay technologies have evolved over decades to become the cornerstone of modern diagnostic testing. From the early use of radioactive methods to the current dominance of chemiluminescence, the development of immunoassay technologies has significantly advanced medical diagnostics. Below is a brief overview of how immunoassay technologies have progressed over the years:
1960s: Radioimmunoassay (RIA)
The 1960s marked the beginning of immunoassay development with the introduction of radioimmunoassay (RIA). This method was widely used due to its low cost and high sensitivity. However, it had significant drawbacks, such as radioactive contamination, short shelf life of reagents, and complex operation procedures. These limitations made RIA less ideal for widespread use in clinical diagnostics.
1970s: Colloidal Gold Technology
In the 1970s, colloidal gold technology was introduced, offering a much simpler and faster process. This advancement was a breakthrough for point-of-care testing due to its ease of use. However, it struggled with low sensitivity, which remained a major issue due to the inherent limitations of the technology itself.
1980s: Enzyme-Linked Immunosorbent Assay (ELISA) & Time-Resolved Fluorescence
In the 1980s, Enzyme-Linked Immunosorbent Assay (ELISA) and time-resolved fluorescence (TRF) emerged as more advanced immunoassay techniques. ELISA, which was primarily developed by domestic manufacturers like Shanghai Kehua, gained popularity due to its low cost and stable properties. However, it could not meet the increasing demand for higher sensitivity and precision, which limited its application for complex diagnostics. On the other hand, time-resolved fluorescence (TRF), as used by companies such as Shanghai Xinnuo, showed improvements in sensitivity but introduced its own challenges, including complex operations, high cost, and long reaction times. Despite these shortcomings, TRF became the foundation for further development in immunoassay technologies, particularly in the domestic market.
1990s: Emergence of Chemiluminescence
The 1990s saw the introduction of chemiluminescence immunoassay (CLIA), a revolutionary technology that quickly gained attention for its high sensitivity, fast detection times, and versatility. While the adoption of CLIA was slow in domestic markets, it gradually gained popularity, especially after the 21st century. With its rise, the market for CLIA-based systems began to expand rapidly, particularly in clinical diagnostics where precision and speed are crucial.
2000s: CLIA Becomes the Mainstream Immunoassay Technology
By the 2010s, CLIA had firmly established itself as the leading technology in immunoassay diagnostics, replacing previous methods like time-resolved fluorescence. The widespread adoption of CLIA was driven by its superior performance and the ability to handle a broader range of diagnostic tests with greater accuracy. Today, CLIA is the dominant method in the immunoassay market, enabling faster, more reliable diagnoses and contributing to better patient outcomes.

Basic Principles of Chemiluminescence (CL) Analysis
Chemiluminescence (CL) is a type of molecular luminescence spectroscopy that relies on the principle of a linear quantitative relationship between the concentration of the substance to be measured and the chemical luminescence intensity under specific conditions. This method uses instruments to detect the system's chemical luminescence intensity to determine the concentration of the target substance. Chemiluminescence is a trace analysis method that distinguishes itself from other types of luminescence analysis in that the energy source for the emitted light (radiation) comes from a chemical reaction, rather than from external light sources. In simple terms, chemiluminescence refers to the phenomenon of light emission accompanying a chemical reaction. It occurs when a chemical reaction generates enough energy to emit light, and the light emitted is used for detecting the concentration of a substance.
Types of Chemiluminescence Analysis Based on Energy Supply Reactions
Chemiluminescence analysis methods can be classified based on the characteristics of the energy-supplying reactions:
- Conventional Chemiluminescence Analysis (the energy-supplying reaction is a general chemical reaction)
- Biochemiluminescence Analysis (the energy-supplying reaction is a biochemical reaction, also known as BCL)
- Electrochemiluminescence Analysis (the energy-supplying reaction is an electrochemical reaction, abbreviated as ECL)
