Which of the following is a potential risk of an autologous transfusion?

• A. The development of a hemolytic disease because if incompatibility.
• B. Inadvertent reinfusion of bacterial and other microbial contaminants.
• C. Development of GVHD between the donor's blood and the recipient.
• D. Acquiring of a new infectious disease from the donor.

Answer: (B)

Verified step by step guidance

1. Step 1: Understand what an autologous transfusion is. It involves collecting and reinfusing a patient's own blood, which eliminates the risk of immune incompatibility reactions that can occur with donor blood.
2. Step 2: Recognize that because the blood is the patient's own, risks like hemolytic disease due to incompatibility or graft-versus-host disease (GVHD) are highly unlikely in autologous transfusions.
3. Step 3: Consider the potential risks unique to autologous transfusions, such as contamination. Since the blood is collected and stored before reinfusion, there is a risk of bacterial or microbial contamination during this process.
4. Step 4: Understand that acquiring new infectious diseases from a donor is not a risk in autologous transfusions because the blood is from the same individual, not from a different donor.
5. Step 5: Conclude that the primary potential risk in autologous transfusion is the inadvertent reinfusion of bacterial and other microbial contaminants, which can lead to infection.
