Global Immunoprotein Diagnostic Testing Market

Industry size, competitive landscape, segmentation & forecast (2026–2036)

Executive summary

Immunoprotein diagnostic testing (immunoassays that measure antibodies, immunoglobulins and related proteins) is central to clinical immunology, infectious disease diagnostics, autoimmune disease monitoring, and therapeutic monitoring. Growth is driven by expanded screening programs, rising autoimmune and infectious disease burden, point-of-care adoption, and improved assay sensitivity (e.g., chemiluminescence, ELISA, lateral flow).

In 2017 the market was valued at US$ XX million and is forecast to reach US$ XX million by 2036 (CAGR: XX%, 2026–2036). Key demand pockets: hospital laboratories, reference labs, point-of-care settings and research/biotech.

Porter’s Five Forces

• Threat of new entrants: Moderate — moderate capital to scale but high regulatory/validation burden.

• Supplier power: Moderate — specialized antibodies, assay chemistries and detection platforms are supplied by a concentrated vendor base.

• Buyer power: High — large hospitals, group purchasing organizations and reference labs negotiate on price, service and integration.

• Threat of substitutes: Low–Moderate — molecular diagnostics substitute for some infectious disease applications, but immunoprotein tests remain essential for many indications.

• Competitive rivalry: High — incumbents compete on assay performance, automation compatibility, multiplexing and service.

SWOT analysis
