C-Reactive Protein (CRP) Test

The C-reactive protein (CRP) test is a blood test that measures the levels of CRP in the bloodstream. CRP is a protein produced by the liver in response to inflammation in the body. The CRP test is commonly used as a marker of inflammation and can help identify and monitor various inflammatory conditions. The test is useful in diagnosing and monitoring infections, autoimmune disorders, cardiovascular diseases, and certain types of cancer. Elevated levels of CRP indicate the presence of inflammation, though it cannot pinpoint the exact cause or location of the inflammation.
