Abstract

Immunoassay techniques are powerful analytical tools that exploit the high specificity of antigen–antibody interactions for qualitative and quantitative analysis of biological molecules. These techniques play a crucial role in clinical diagnostics, pharmaceutical analysis, biomedical research, food safety, and environmental monitoring. Over the years, immunoassays have evolved from classical radioimmunoassays to highly sensitive chemiluminescent, fluorescence-based, biosensor-coupled, and point-of-care systems. This review provides a comprehensive discussion on the principles, classification, working mechanisms, advantages, limitations, recent advancements, and applications of various immunoassay techniques, supported by updated scientific references.
