Increased CRP levels are found in inflammatory conditions including: bacterial infection, rheumatic fever, active arthritis, myocardial infarction, malignancies and in the post-operative state. This test cannot detect the relatively small elevations of CRP that are associated with increased cardiovascular risk.

Most tissue-damaging processes such as infections, inflammatory diseases and malignant neoplasms are associated with a major acute phase response of the C-reactive protein (CRP) and other acute reactants e.g. AAT, AAGP, C3C, C4 HAPT. The CRP response frequently precedes clinical symptoms, including fever. In normal healthy individuals CRP is a trace protein with a range up to 5 mg/L. After onset of an acute phase response the serum CRP concentration rises rapidly and extensively. Levels of up to thousand times the normal value are associated with severe stimuli such as myocardial infarction, major trauma, surgery or malignant neoplasm. CRP has a half-life of only a few hours, making it an ideal tool for clinical monitoring.
