C-reactive Protein(CRP) Determination Reagent is an in vitro diagnostic quantitative test kit. CRP is an acute protein that rises sharply in the serum when the body is infected or damaged. It plays an important protective role in the body's natural immune process. CRP is extremely low in normal human serum, and it can rise sharply within a few hours when tissue is damaged, inflammatory, and infected. It can increase several times or hundreds of times, peaking in 2-3 days, and gradually decreasing when the condition improves. CRP is widely used in early diagnosis and differential diagnosis of clinical diseases.
