When interpreting C-reactive protein labs, the main purpose is to check whether the value of C-reactive protein is elevated and the degree of elevation, and then combine with the patient’s signs and symptoms to comprehensively analyze the condition. C-reactive protein is an acute-phase response indicator, with normal values ranging from 0 to 10 mg/L. Elevated values are common in bacterial infections, rheumatic immune diseases, and also in malignant tumors, surgical trauma, and burns. C-reactive protein plays an important role in determining the cause of fever and monitoring rheumatic immune diseases. When a bacterial infection occurs in the human body, C-reactive protein often rises quickly and can be greater than 100mg/L. When a viral infection occurs, C-reactive protein is often not elevated or is only mildly elevated. C-reactive protein is also elevated when rheumatic immune diseases such as systemic lupus erythematosus and rheumatoid arthritis are in an active stage or when the disease is aggravated. It is recommended that the patient should consult a doctor in time after completing the C-reactive protein test, and the doctor will make a comprehensive judgment on the condition and the C-reactive protein value, and formulate a treatment plan.
