How high is the C-reactive protein (CRP) level in whole blood considered dangerous?

　　Whole blood CRP usually refers to serum C-reactive protein. Generally speaking, there is no absolute numerical threshold indicating at what level serum C-reactive protein becomes dangerous, as the degree of risk also depends on the individual's specific condition, accompanying symptoms, and the severity of the underlying disease.

　　Serum C-reactive protein is a relatively sensitive indicator reflecting various infectious and non-infectious inflammatory conditions in the body and serves as a non-specific marker of systemic inflammation. The normal reference range may vary depending on the laboratory and testing methods, but it is typically between 0-10 mg/L or 0-5 mg/L.

　　When serum C-reactive protein levels exceed the normal range, it may indicate the presence of inflammation or infection within the body. If serum C-reactive protein remains persistently elevated, especially exceeding 40 mg/L or higher, it may suggest more severe inflammation; however, the exact level of risk must be determined comprehensively considering other factors.

　　When elevated serum C-reactive protein levels are detected, patients are advised to seek medical attention promptly, where a physician will make a diagnosis and initiate treatment based on the individual's specific condition. Doctors will evaluate the patient's symptoms, physical signs, and medical history comprehensively to formulate a personalized treatment plan. During treatment, patients should also maintain healthy lifestyle habits and a positive mindset to promote recovery.
