Use:C-Reactive Protein, Inflammatory (CRP) is used as an indicator of infectious and inflammatory disease states, including active rheumatic fever and rheumatoid arthritis. CRP is the most sensitive acute phase protein and rises within two hours of acute insult (surgery, infection, etc.) If no other event occurs, CRP will peak at about 48 hours and then begin to decrease.
