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

Regarding the question of how high C-reactive protein (CRP) levels must be to warrant intravenous (IV) infusion, the decision should be made based on the patient's specific condition, other clinical test results, and the physician's comprehensive judgment. C-reactive protein is a nonspecific inflammatory marker. Its normal reference range varies depending on the population being measured, but for healthy adults, it is generally between 0.42 and 5.2 mg/L. Elevated CRP levels 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 necessary. 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 must also take into account the patient's individual circumstances, including the type of infection, the severity of illness, the patient's age, and overall health status, to formulate an appropriate treatment plan.
