Whole blood c-reactive protein 56 is considered high. The common causes of elevated whole blood c-reactive protein include bacterial infection, tissue injury, and immune dysfunction. 1. Bacterial infection: when the body is infected with bacteria, c-reactive protein rises sharply, activating complement and strengthening phagocytosis to phagocytose bacteria and remove pathogenic bacteria invading the body. 2. Tissue damage: when trauma, surgery, burns and other tissue damage and necrosis, C-reactive protein will also rise to varying degrees, so as to remove necrotic, apoptotic tissue cells. 3. Immune dysfunction: when suffering from autoimmune diseases such as rheumatoid arthritis, the long-term stimulation of inflammation, the body’s inflammatory factors increase, which in turn leads to high whole blood C-reactive protein. There may be other reasons for elevated C-reactive protein, so it is recommended to go to the hospital in time to improve the examination to clarify the cause of the disease and then give targeted treatment.
