Bronchopneumonia C-reactive protein is not high, which mostly suggests that the pathogen infecting bronchopneumonia may be a virus and not a bacteria. Bronchopneumonia, also called lobular pneumonia, is usually caused by bacteria, respiratory viruses, Mycoplasma pneumoniae and other infections. Clinical symptoms are fever, cough and sputum. It mostly occurs in infants and young children and the old and frail. C-reactive protein is a commonly used clinical test, mainly used to determine whether the bacterial infection and the severity of the infection. If C-reactive protein is significantly elevated, more than 10mg/dl, it suggests that the inflammation is obvious and mostly caused by bacterial infection, and antibiotic treatment can be given; if C-reactive protein is not elevated or the elevation is not obvious, it often suggests that the pathogen is a virus. But there are other possibilities, such as the body’s immune system is in a state of inhibition of the inflammatory response is not obvious, or physical and chemical factors stimulation caused by inflammation. Therefore, after the C-reactive protein test, should hold the results of the test to see the doctor, do not take medication without authorization, in order to avoid misunderstanding the condition, resulting in adverse outcomes.
