How high must the C-reactive protein level be before intravenous infusion is required?

There is no fixed standard value for exactly how high C-reactive protein (CRP) levels must be before intravenous (IV) infusion becomes necessary. The decision must be made based on the patient's specific condition, other clinical test results, and the physician's comprehensive judgment. C-reactive protein is a non-specific inflammatory marker. Its normal reference range varies depending on the population being measured, but generally falls between 0.42 and 5.2 mg/L in adults. An elevated CRP level may indicate the presence of infection, inflammation, or tissue damage in the body. However, CRP levels alone cannot directly determine whether IV infusion therapy is required. In certain situations, such as severe infection, dehydration, or when it is necessary to maintain fluid and electrolyte balance, physicians may consider IV infusion therapy. However, treatment decisions should also take into account the patient's specific circumstances, including the type of infection, severity of illness, age, and overall health status, in order to formulate an appropriate treatment plan.
