C-Reactive Protein (CRP) is an acute-phase protein, produced only in the liver. The concentration of CRP in plasma or serum increases significantly in the presence of infectious and noninfectious inflammation, tissue damage and in the presence of malignant tumours. CRP is present in the active stages of inflammatory disorders like rheumatoid arthritis, ankylosing spondylitis, Reiter’s syndrome, psoriatic arthropathy, systemic lupus erythematosus, polyarteritis, ulcerative colitis and Crohn’s disease. CRP is used in many parts of the world as a screening test when a patient is admitted to the ER or hospital, although its use in the United States is not as prevalent.
