Ultrasensitive c-reactive protein, 57 mg/L, is already higher than normal and is considered abnormal. Ultrasensitive c-reactive protein is a c-reactive protein in plasma. In the acute phase of systemic inflammatory response, ultrasensitive c-reactive protein is a nonspecific marker synthesized by the liver and is one of the predictors of cardiovascular risk events. The normal value of ultrasensitive c-reactive protein is usually less than 10mg/L. Ultrasensitive c-reactive protein 57mg/L, which is higher than the normal value, indicates that the patient has a disease in the body, which may be cardiovascular and cerebrovascular diseases, serious infections, rheumatic immune disorders, malignant tumors, and traumatic injuries to the body, and it is especially important for the diagnosis of coronary artery disease as well as atherosclerosis as a guiding significance. When the patient has non-infectious factors, there is tissue necrosis, injury, and there are signs of inflammation, there will be elevated c-reactive protein, such as severe pancreatitis, surgery, cardiac infarction, cerebral infarction, burns and so on. When an elevated ultrasensitive C-reactive protein is found, the patient should go to the hospital in time.
