CRP is synthesized in liver and consists of five identical polypeptide chains forming a five-membered ring of molecular weight of 120 kD. CRP is one of the most characteristic acute-phase proteins and is considered as a reliable indicator of disease activity in various clinical conditions. Its concentration in blood increases rapidly by as much as 1000-fold upon exposure to various inflammatory stimuli. CRP has been used successfully for clinical diagnosis and monitoring of a variety of infections and diseases, including infections caused by bacteria, fungi, and viruses; intercurrent infections in leukemia and systemic lupus erythematosus; noninfectious inflammatory diseases such as rheumatoid arthritis; and diseases with cellular necrosis such as myocardial infarction. Measurements of CRP are especially useful in distinguishing viral from bacterial infections.

SAA is a sensitive inflammatory marker discovered in recent years. As an acute-phase reactive protein, its concentration increases significantly in acute and chronic inflammatory reactions, reaching more than 1000 times the normal level in 6-8 hours. As SAA has a short half-life, when the body’s inflammatory response is controlled, SAA rapidly drops to the normal level, which makes SAA a sensitive indicator of the body’s inflammatory state such as infection or trauma. In normal conditions, SAA concentration in serum is approximately 1-10 μg/ml. However, during an acute-phase reaction, the concentration can rise to 1 mg/mL or even higher. SAA can be used in diagnosis, predicting outcomes and assessing the efficacy of treatment in patients with inflammation.
