Which of the following is the MOST common infectious complication of transfusion?
Your Answer
Correct Answer
Explanation
Bacterial contamination is the most common infectious transfusion-related complication, significantly higher than the risk of transfusion-transmitted viral infection. Bacterial contamination of platelet components occurs because platelets are stored at room temperature, which facilitates bacterial growth. Approximately 1 in 1,000-3,000 platelet units may be contaminated with bacteria. The incidence of bacterial contamination with red blood cells and other products is lower.
