C-Reactive Protein (CRP)
About Test
The C-Reactive Protein (CRP) assay measures the concentration of CRP, a marker of inflammation, in the bloodstream. CRP is produced by the liver in response to inflammation, infection, or tissue damage. This test is invaluable in diagnosing and monitoring various inflammatory conditions, such as infections, autoimmune disorders, and cardiovascular diseases. Elevated levels of CRP may indicate acute or chronic inflammation, and the magnitude of the elevation can correlate with the severity of the inflammatory response. Physicians often utilize CRP testing to assess disease activity, guide treatment decisions, and monitor the effectiveness of therapies. Additionally, CRP testing can help identify individuals at higher risk of developing cardiovascular events, such as heart attacks or strokes. Integrating CRP testing into clinical practice allows for early detection and intervention, ultimately improving patient outcomes and quality of life.
