What is the primary purpose of HLA typing in organ donation?

• A. To determine blood type compatibility
• B. To assess tissue compatibility
• C. To evaluate organ function
• D. To monitor infection risk

Answer: (B)

The primary purpose of HLA typing in organ donation is to assess tissue compatibility. HLA, or human leukocyte antigen, plays a crucial role in the immune system, particularly in the recognition of foreign tissues. When a transplant occurs, the recipient's immune system must not reject the donor organ. HLA typing is a method used to identify specific markers found on the surface of cells that are essential for determining compatibility between donor and recipient tissues. A close match in HLA types reduces the risk of the recipient's immune system attacking the transplanted organ, thereby improving the likelihood of transplant success and long-term survival of the organ. In contrast, determining blood type compatibility is important, but it is a separate process. Evaluation of organ function and monitoring infection risk are relevant to the overall transplant process but are not directly associated with HLA typing's central role in ensuring tissue compatibility.
