Chemiluminescent Immunoassay (CLIA) is an advanced diagnostic technology that detects the concentration of antigens or antibodies in blood and other bodily fluids using chemiluminescent reactions. When target molecules bind with specific reagents, light is emitted, which is then captured and quantified by high-performance analyzers.

Compared to traditional testing methods, CLIA offers superior sensitivity, specificity, and automation, making it ideal for high-throughput clinical testing. It is widely applied in:
• Thyroid function testing
• Tumor marker detection
• Infectious disease screening
• Comprehensive hormonal analysis
