By test type, antibody testing leads with a 64% share, while antigen-antibody combination assays are the fastest-growing at approximately 7.4% CAGR. Chemiluminescence immunoassay (CLIA) is the leading technology at 38% (52% including electrochemiluminescence), and multiplex immunoassays are the fastest-growing at approximately 9.5%. Infectious disease testing accounts for 56% of demand and autoimmune testing is the fastest-growing application at approximately 7.6%; correspondingly, viral infections form the largest disease/condition group at 41% and autoimmune diseases the fastest-growing. Serum is the dominant sample type at 58%, with capillary blood the fastest-growing at approximately 8.6%, while hospitals are the largest end user at 41% and point-of-care settings the fastest-growing at approximately 9.5%.
Growth is underpinned by the persistent burden of HIV, viral hepatitis, syphilis and vector-borne infections, mandatory blood-donor and antenatal screening, rising diagnosis of autoimmune and allergic disease, and expanding laboratory infrastructure in emerging markets. Key trends include consolidation onto fully automated, high-throughput chemiluminescence platforms, multiplex autoantibody and allergen panels, AI-assisted immunofluorescence interpretation, LIS-connected digital workflows and decentralized rapid serology. Principal challenges include China’s volume-based procurement pricing reforms, reagent and capital costs, cross-reactivity and assay-standardization limitations, regulatory and quality-control burden under frameworks such as the EU IVDR, and uneven testing infrastructure in low-income settings.
The competitive landscape is moderately concentrated around diversified in-vitro diagnostics leaders - Roche Diagnostics, Abbott, Siemens Healthineers and Danaher’s Beckman Coulter - whose installed bases of automated immunoassay analyzers generate recurring reagent revenue, alongside specialty leaders such as DiaSorin, bioMérieux, Thermo Fisher Scientific and QuidelOrtho. With COVID-related volatility largely absorbed, the market enters 2026 on a steady, menu- and automation-led growth path, with emerging-market adoption, autoimmune and allergy specialty testing, and multiplex and point-of-care formats offering the strongest incremental opportunities through 2030.
