Introduction
In general, a high-sensitivity C-reactive protein (hs-CRP) level of over 50 mg/L does not require intravenous infusion. C-reactive protein is an acute-phase reactant protein, with a normal reference range typically between 0–5 mg/L. A CRP level of over 50 mg/L indicates a mild elevation, which may be caused by factors such as intense physical exercise, trauma, or infection.
Under normal circumstances, a high-sensitivity C-reactive protein (hs-CRP) level of over 50 mg/L generally does not require intravenous infusion, but infusion may be necessary if the condition is severe. The detailed analysis is as follows:
1. Not required
High-sensitivity C-reactive protein is an acute-phase reactant, with a normal reference range typically between 0–5 mg/L. An hs-CRP level above 50 mg/L indicates a mild elevation, which may result from intense physical exercise, trauma, infection, or other causes. If the elevation is due to factors such as strenuous exercise or injury, intravenous therapy is usually unnecessary and symptoms often resolve with rest. However, if the cause is infection, treatment under a doctor's guidance with medications such as amoxicillin capsules or cefixime capsules may be needed.
2. Required
If the patient also experiences symptoms such as cough and fever, shows significantly elevated white blood cell count and neutrophils in complete blood count, and chest CT reveals patchy areas of high density, pulmonary infection should be considered. In such cases, intravenous infusion therapy is recommended. Doctors typically use injectable antibiotics such as cefoperazone sodium or cefotaxime sodium.
Patients are advised to ensure adequate rest, avoid excessive fatigue, maintain warmth, and prevent cold exposure in daily life. If significant discomfort occurs, prompt medical attention is essential to avoid delays in diagnosis and treatment.
