Ultrasensitive C-reactive protein has a normal range of 0.5-10 mg/L. Ultrasensitive C-reactive protein can be a sensitive indicator of infectious disease in the body. In many cases, routine blood tests do not show high levels of white blood cells, but this test can reflect infectious diseases, including common bacterial infections. This test can also reflect the risk of heart disease. Persistent low levels of inflammation play a major role in atherosclerosis, which is caused by the accumulation of cholesterol and other lipids, resulting in a sterile inflammation and an increase in ultrasensitive C-reactive protein. It therefore helps to predict the risk of cardiovascular disease in patients and contributes to early prevention. This indicator is also increased after surgery or trauma to the body, mainly due to trauma that leads to a series of inflammatory reactions in the body, resulting in an increase in ultrasensitive C-reactive protein.
