C-reactive protein 100 indicates the presence of a serious infection or non-infectious injury such as an acute cardiovascular accident, requiring active management of the primary disease. C-reactive protein is an acute time-phase protein with a normal value of 0-10mg/L. When inflammation or trauma exists in the body, C-reactive protein will rise rapidly. 1. When severe bacterial infection exists, C-reactive protein can be elevated to 100 or even 200, while viral infection C-reactive protein is usually not significantly elevated. When the white blood cell count is normal but C-reactive protein is elevated to 100 in routine blood tests, serious bacterial infections should be considered, and the patient should actively cooperate with the doctor for anti-infective treatment. 2. When there is non-infectious injury, such as acute myocardial infarction, C-reactive protein rises rapidly to more than 100, indicating that the myocardial cells are seriously damaged, and need to cooperate with the doctor in time for treatment.
