Key Market Takeaways

Leading Product Segment: Reagents and Kits Dominate

Among the various product types, reagents and kits continue to hold the lion’s share—60% of global revenue—and are projected to retain this lead through 2032. Their broad application in testing new and evolving pathogens, especially during global health crises, has propelled demand. The launch of novel, highly sensitive reagent kits is accelerating the pace of testing, making this segment indispensable for hospitals, labs, and point-of-care diagnostics.

Technology Spotlight: EIA/ELISA Leads the Pack

Enzyme Immunoassays (EIA), including ELISA, account for approximately 60% of the technology segment, thanks to their accuracy, quick turnaround time, and efficiency in managing high testing volumes. This technology is especially impactful in reducing assay time for immunodiffusion and immunoelectrophoresis. Meanwhile, rapid test technologies are gaining ground in managing outbreaks related to Zika, Salmonella, Campylobacter, and Listeria.

Infectious Disease Testing Remains the Primary Application

By application, infectious disease testing dominates the immunoassay space, generating 30% of global revenue. The consistent rise in HIV, influenza, malaria, and COVID-19 cases has fueled the need for accurate and scalable diagnostic solutions. This trend is expected to continue as new virus strains emerge and global healthcare systems prioritize rapid containment and diagnosis.

Geographic Insights

North America Maintains Market Leadership

North America accounted for 35% of global immunoassay market revenue in 2022, and is projected to maintain its dominance through 2032. This is attributed to:

  • A growing geriatric population
  • High incidence of chronic illnesses such as cancer and autoimmune diseases
  • Readily available advanced diagnostic infrastructure
  • Increased adoption of molecular diagnostic kits and automated testing platforms

Asia-Pacific: The Fastest Growing Market

The Asia-Pacific region emerges as the fastest-growing market, driven by increased government spending on healthcare infrastructure, especially in India and China. Rapid urbanization, a booming elderly population, and a surge in chronic lifestyle diseases contribute to the rising demand for diagnostic tools. The aftershock of COVID-19 has further spurred a widespread need for mass testing capabilities, significantly boosting sales of immunoassay kits.
