Introduction
When the value is within the range of 3-10 mg/L, although it has not reached the level of severe risk, it has exceeded the ideal healthy range and may be associated with a chronic inflammatory state. This mild elevation is commonly seen in conditions such as vascular endothelial inflammation and metabolic abnormalities. Prolonged maintenance at this level increases the likelihood of cardiovascular-related issues, and further examinations are needed to identify the underlying cause.
Generally, when high-sensitivity CRP exceeds 10 mg/L, attention should be paid to potential health risks. If the level remains consistently above 30 mg/L, it may indicate the presence of a serious infection or inflammatory condition. If abnormalities are detected, timely medical consultation is recommended. Detailed explanation is as follows:
When the value falls within the range of 3-10 mg/L, although it hasn't reached the threshold for severe risk, it has already exceeded the optimal healthy range and may be associated with a chronic inflammatory state. This mild elevation is commonly seen in conditions such as vascular endothelial inflammation and metabolic abnormalities. Maintaining this level over a prolonged period increases the likelihood of cardiovascular-related issues, and further investigations are needed to identify the underlying cause.
When high-sensitivity CRP exceeds 10 mg/L, especially when persistently above 30 mg/L, the level of risk significantly increases. This is often associated with acute infection, severe inflammation, or tissue damage. It may be accompanied by symptoms such as fever and pain. If not promptly treated, the infection or inflammation may progress, affecting organ function and even triggering systemic health complications. Targeted diagnostic tests and treatment should be initiated as soon as possible.
The clinical significance of high-sensitivity CRP can vary depending on the testing context. Test results must be interpreted in combination with symptoms, medical history, and other laboratory indicators. A single CRP value alone should not be used to determine health status. It is essential to consult a physician for proper interpretation of results and to develop an appropriate follow-up plan.
