Market Growth Factors
The global immunoassay market is being propelled by the escalating incidence of chronic and infectious diseases worldwide. Immunoassay’s inherent specificity, high-throughput capabilities, and exceptional sensitivity suit it for precise disease diagnosis and therapeutic drug monitoring. These advantages enable its growing adoption in disease diagnosis, clinical pharmacokinetics, and drug discovery, fostering sustained market growth.
Furthermore, its fast, simple, and cost-effective features are enabling it to replace conventional testing methods such as high-performance liquid chromatography (HPLC) and gas chromatography (GC), particularly for on-site food contamination analysis. This shift is further supported by stringent regulatory frameworks related to food safety, leading to increased demand in the food testing segment.
Innovations in immunoanalytical systems such as surface plasmon resonance (SPR)-based instruments utilizing bioengineering, microfluidic, and biosensor technologies are creating new opportunities for market expansion. Additionally, the emergence of smartphone-based diagnostic formats and multiplex bead assays is driving demand for real-time health monitoring and facilitating advances in in vitro diagnostics across healthcare, research, and agriculture.
