C-Reactive Protein Testing Market Summary
The C-Reactive Protein (CRP) testing market is a cornerstone of the global in-vitro diagnostics (IVD) industry, serving as a vital indicator for systemic inflammation, infection, and tissue damage. CRP is an acute-phase reactant protein synthesized by the liver, and its concentration in the blood rises rapidly in response to various pathological triggers. This market is characterized by its broad utility across clinical disciplines, ranging from cardiovascular risk assessment to the monitoring of autoimmune disorders and neonatal sepsis. The industry is currently undergoing a structural shift toward high-sensitivity CRP (hs-CRP) assays and decentralized point-of-care (POC) testing, driven by the need for rapid diagnostic turnaround times and the rising prevalence of chronic non-communicable diseases.

The global C-Reactive Protein Testing market is estimated to reach a valuation of approximately USD 3.0–6.0 billion in 2025. The market is projected to expand at a compound annual growth rate (CAGR) of 1.0%–7.0% through 2030. While the industry is mature in developed economies, growth is sustained by the integration of CRP testing into routine health screenings and the expanding geriatric population, which inherently carries a higher burden of inflammatory conditions. The market’s stability is further reinforced by its essential role in managing infectious diseases and the increasing adoption of personalized medicine, where CRP levels help tailor therapeutic interventions for chronic inflammatory states.

Digitally Connected POC Devices: The integration of Bluetooth and cloud connectivity into portable CRP readers allows for the real-time transmission of results to telehealth platforms, supporting the growing trend of remote patient management.

Challenges

Lack of Diagnostic Specificity: CRP is a "non-specific" marker; while it tells a clinician that inflammation is present, it does not reveal the cause. This inherent limitation can lead to diagnostic ambiguity and necessitates that CRP be used as part of a wider panel of tests.

Pricing Pressures & Reimbursement: In many markets, CRP testing is viewed as a "commodity" test. Diagnostic providers face intense pricing competition and strict reimbursement caps from government and private insurers, which can limit the margins on high-volume laboratory testing.

Competition from Novel Biomarkers: Newer biomarkers, such as Procalcitonin (PCT) and Interleukin-6 (IL-6), are increasingly used alongside or in place of CRP for specific conditions like sepsis or severe COVID-19. Maintaining CRP's clinical relevance in the face of these specialized alternatives is a continuous challenge.
