C-Reactive Protein Testing Market: Assay Technologies, Rapid Testing Innovation, and Competitive Developments

Assay technology and testing format are central to how the C-reactive protein testing market is evolving. Polaris Market Research reports that the market was valued at USD 2.9 billion in 2024 and is projected to reach USD 6.7 billion by 2034, at a CAGR of 8.80% from 2025 to 2034. North America was the largest market in 2024. This article examines assay types, detection ranges, and innovation.

Assay Types and Segmentation

The report segments the market by assay type into immunoturbidimetric assays, ELISA, chemiluminescence immunoassay, and others. It further segments by detection range into hs (high sensitivity) CRP, conventional CRP, and cCRP, and by end-use into clinics, hospitals, laboratories, assisted living healthcare facilities, home care settings, and others.

Immunoturbidimetric assays accounted for the largest revenue share in 2024. Their application in chronic diseases of the respiratory and cardiac systems contributes to their dominance, and advancements in the chemiluminescence immunoassay (CLIA) process, providing accurate results, will further drive growth in this segment. Researchers worldwide are developing innovative assays to support rapid and precise CRP testing. In January 2021, investigators from D.M. Vasudevan Agappe Diagnostic Limited, India, established the use of a latex-enhanced immunoturbidimetric assay for highly sensitive, wide-range CRP detection in human serum.

High-Sensitivity Testing

The high-sensitivity C-reactive protein (hs-CRP) testing segment is expected to witness the fastest growth during the forecast period, driven by advancements in CRP technologies. Compared with traditional CRP tests, hs-CRP testing is highly sensitive and can detect even small increases in CRP levels, which makes it valuable for identifying cardiac risk.

Introducing nano-bio hybrid materials in CRP biosensors has emerged as an advantageous procedure for rapid and accurate CRP measurement using portable biosensors. In a study published in May 2021, researchers from Korea outlined advances in spectroscopy-based, electrical, and electrochemical CRP biosensors comprising nanomaterial hybrids and biomaterials, which Polaris Market Research expects to boost adoption of advanced CRP tools.

Point-of-Care Advances

Adoption of point-of-care devices is among the factors expected to raise demand, and the market is seeing the development of hs-CRP-based point-of-care testing devices by different market entities. A study from Babeș-Bolyai University in Romania, published in July 2021, reviewed assays based on plasmonic nanoparticles for detecting CRP and demonstrated recently developed point-of-care assays for fast CRP testing. Government-supported initiatives also emphasize point-of-care screening to enhance accessibility and convenience.

Commercial products reflect this shift. Aidian provides QuikRead go CRP tests and a portable QuikRead go instrument for quantitatively measuring CRP, and Abbott provides the Afinion CRP and Afinion 2 Analyzer test, which delivers results in just 3 minutes.

AI Integration and Recent Developments

AI enables faster and more accurate CRP analysis by automating interpretation and reducing manual errors, while AI-driven analytics improve clinical decision-making by cross-referencing CRP with patient history. Machine learning can also detect inflammation-linked changes from ECG or large datasets. Automation and AI integration also streamline laboratory workflows, increase efficiency, and cut costs. In September 2025, HORIBA announced a strategic partnership with GeodAIsics to develop an AI-driven solution for early sepsis detection, integrating hematology analyzers, including HORIBA's CRP-enabled systems, to identify infection and inflammation patterns at an early stage.

Restraints and Competitive Landscape

The high cost and lack of standardized reimbursement are projected to hamper market growth. Companies working in the global CRP market include Abaxis, Inc.; Abbott, Danaher; Aidian; BODITECH MED, INC.; F. Getein Biotech, Inc.; Hoffmann-La Roche Ltd.; HORIBA, Ltd., Inc.; Laboratory Corporation of America Holdings; Merck KGaA; Ortho Clinical Diagnostics; Quest Diagnostics; Randox Laboratories Ltd.; Roche Ltd.; Siemens Healthineers AG; Thermo Fisher Scientific; and Zoetis. Polaris Market Research describes intense competition shaped by technological advancements, product differentiation, strategic collaborations, and a focus on research and development.

Assay choice, sensitivity, and testing format continue to shape competition. The full Polaris Market Research report provides further segment and regional detail.

Conclusion

The C-reactive protein testing market is experiencing continued demand due to the growing need for inflammation assessment, infection evaluation, and chronic disease monitoring. Increasing awareness regarding early disease detection and the importance of laboratory diagnostics is encouraging the adoption of CRP testing solutions. Technological advancements in rapid diagnostic platforms, point-of-care testing, and automated laboratory systems are improving testing accessibility and operational efficiency. Furthermore, the growing emphasis on preventive healthcare and timely clinical decision-making is supporting market opportunities. However, limitations in test specificity, interpretation requirements, and varying healthcare reimbursement policies may influence adoption. Overall, the market is expected to maintain a favorable outlook as healthcare providers prioritize efficient diagnostic testing and improved patient management.
