Blood Crp test refers to the measurement of C-reactive protein in the patient’s blood. 1. Blood Crp is an indicator of inflammation. In patients with acute bacterial infections, blood Crp is elevated, usually accompanied by elevated white blood cells and neutrophils, and the degree of elevation is directly proportional to the severity of the infection; in patients with viral infections, blood Crp is normal. Therefore, blood Crp can be used to reflect not only the type of inflammation, but also the severity of inflammation. 2. Blood Crp can also be used to identify pneumonia and bronchitis, to determine the severity of acute pancreatitis, to determine the degree of activity of systemic lupus erythematosus and rheumatoid arthritis, and to determine whether the patients after organ transplantation have undergone a rejection reaction and the diagnosis of Kawasaki disease. 3. In addition, in the event of myocardial infarction and other tissue and organ damage, blood crp index will also be significantly higher. Warm tips: patients should not stay up all night, drink alcohol, and draw blood on an empty stomach before testing blood Crp. If the blood Crp test is abnormal, further perfect examination should be carried out to clarify the reasons for the elevation of Crp, and treatment should be carried out under the guidance of doctors.
