High C-reactive protein often suggests a variety of acute inflammation, tissue injury, myocardial infarction, surgical trauma, radiological damage and other diseases, and is usually rapidly elevated a few hours after the onset of the disease, and then rapidly decreases to normal when the disease improves, and its elevation is positively correlated with the degree of infection. C-reactive protein plays an active role in the inflammatory response, giving the body nonspecific resistance. Once inflammation occurs, C-reactive protein levels are elevated, while C-reactive protein is mostly normal in viral infections and elevated in patients with malignant tumors, and elevated C-reactive protein levels can also be used to assess the severity of acute pancreatitis.
