C Reactive Protein Testing Market Size

The global c reactive protein testing market size was valued at USD 3.29 billion in 2025 and is projected to grow from USD 3.37 billion in 2026 to USD 4.06 billion by 2034, registering a CAGR of 2.37% during the forecast period from 2026 to 2034. North America dominated the c reactive protein testing market with a market share of 38.5% in 2025.

A c-reactive protein test measures the amount of c-reactive protein (CRP) in a blood sample. The liver produces the protein CRP. C-reactive protein levels in the blood are typically low. If there is inflammation throughout the body, the liver releases more CRP into the bloodstream. Having a significant health issue that generates inflammation and high levels of CRP could be a sign of that. A CRP test can reveal whether and how much inflammation exists in the body. The test, however, cannot determine what is causing the inflammation or which area of your body is affected. A CRP test may detect or track inflammation in short-term or long-term illnesses, such as Viral or bacterial infections; disorders of the intestines, such as Crohn's disease and ulcerative colitis, are examples of "inflammatory bowel disease." Vasculitis, lupus, and rheumatoid arthritis are examples of autoimmune diseases and lung conditions like asthma.
