Immunoassay (IA) is a technique used to measure the concentration of analytes in a solution with an antibody or an antigen as a biorecognition agent. It plays a crucial role in clinical diagnostics, pharmaceutical analysis, environmental monitoring, and security. It is widely used in research centers, hospitals, and laboratories to diagnose different diseases and improve the overall health and well-being of humans and animals. Moreover, as it is fast, simple, and cost-effective, IA is rapidly replacing conventional tests, such as high-performance liquid chromatography (HPLC) and gas chromatography (GC), for on-site analysis of food contamination.

The escalating number of individuals suffering from chronic and infectious diseases represents one of the key factors propelling the market growth. As IA offers inherent specificity, high-throughput, and high sensitivity for the analysis of biological samples, it is used in disease diagnosis, therapeutic drug monitoring, clinical pharmacokinetics, and drug discovery around the world. Moreover, automation, versatility, and the speed of analysis, along with stringent regulatory framework regarding food safety, is influencing the demand for IA in food testing. Apart from this, researchers are developing prominent immunoanalytical systems, including surface plasmon resonance (SPR)-based instruments using bioengineering, microfluidic, and biosensor technologies. These systems help in the detection of analytes and the screening of immunological components based on biomolecular interactions. Furthermore, the emerging trend of smartphone-based formats and multiplex bead assays is anticipated to drive the demand for IAs for managing health complications in real-time and enabling in vitro diagnostics.
