The chemiluminescence immunoassay market size is expected to reach USD 18.97 billion by 2034, according to a new study by Polaris Market Research. The report “Chemiluminescence Immunoassay Market Size, Share, Trends, Industry Analysis Report: By Product (Instruments, Consumables, Reagents, and Others), Sample Type (Blood, Urine, Saliva, and Others), Technology, Application, and Region (North America, Europe, Asia Pacific, Latin America, and Middle East & Africa) – Market Forecast, 2025–2034” gives a detailed insight into current market dynamics and provides analysis on future market growth.

The chemiluminescence immunoassay (CLIA) market growth is attributed to the increasing demand for accurate, efficient, and high-sensitivity diagnostic solutions. A few key drivers of the market growth are the rising prevalence of chronic and infectious diseases, the need for early disease detection, and the growing focus on personalized medicine. CLIA market opportunities are fueled by technological advancements such as automation, AI integration, and the development of multiplex assays. Trends such as the expansion of point-of-care testing, the shift toward noninvasive sample types, and the growing adoption of digital platforms further support market growth. The market is expected to expand in the coming years as healthcare infrastructure improves in emerging economies, providing new avenues for growth.

Chemiluminescence Immunoassay Market Report Highlights

The reagents segment, based on product, dominates the chemiluminescence immunoassay market share due to their frequent usage in diagnostic tests. The consumables segment is expected to register the highest growth, driven by the increasing adoption of disposable items such as cartridges and microplates in laboratories and point-of-care settings.

By sample type, the blood sample segment holds the largest share of the market due to its reliability and wide application in various medical tests. Saliva-based testing is the fastest-growing segment, driven by its noninvasive nature and increasing use in disease diagnostics such as COVID-19 and hormonal tests.

The electrochemiluminescence Immunoassay (ECLIA) segment, by technology, holds the largest market share due to its high sensitivity and precision, particularly in detecting low analyte concentrations. The microparticle chemiluminescence immunoassay (MCLIA) segment is expected to grow the fastest, driven by its ability to increase sensitivity and reduce assay times, particularly in high-throughput environments.

The infectious diseases segment, based on application, dominates the CLIA market revenue share due to the high global demand for accurate, rapid diagnostic tests. The oncology segment is expected to witness the highest growth, fueled by the rising incidence of cancer and increasing use of CLIA assays in tumor marker detection and monitoring.

North America leads the chemiluminescence immunoassay (CLIA) market due to its advanced healthcare infrastructure, high adoption of CLIA systems, and large investments in diagnostics. Asia Pacific is the highest growing region, driven by expanding healthcare access, rising chronic and infectious disease prevalence, and increasing healthcare expenditures in emerging markets such as China and India.
