Use

C-reactive protein (CRP) is a sensitive acute-phase reactant for inflammation, synthesized by the liver. Measuring CRP can help detect systemic inflammatory processes and assess response to treatment of bacterial infections. It is useful for differentiating between active and inactive disease forms with concurrent infection, such as in systemic lupus erythematosus or ulcerative colitis. Persistent high CRP concentrations generally indicate an uncontrolled infection. Monitoring CRP levels postoperatively can aid in recognizing complications like infected wounds, thrombosis, and pneumonia.
