When should I consider referring a patient with a transfusion reaction to a specialist?

Based on the provided UK guideline excerpts, there is no specific guidance on when to refer a patient with a transfusion reaction to a specialist ¹. The guidelines focus on the importance of monitoring the patient's condition and vital signs before, during, and after blood transfusions to detect acute reactions that may require immediate investigation and treatment ¹. Patients who are having or have had a blood transfusion should be observed in an environment where staff are capable of monitoring and managing acute reactions ¹.
