Which item is collected and maintained in the organ transplant registry?

• A. Histocompatibility information
• B. HLA typing data
• C. Donor medical history
• D. Recipient address and contact information

Answer: (A)

Histocompatibility information is the data that describes how well a donor organ is immunologically suited for a specific recipient. This centers on immune system compatibility—HLAs, ABO type, and crossmatch results—which directly affect the risk of rejection and long-term success after transplant. A transplant registry stores and maintains this information so clinicians can identify the best possible matches and track how well they perform over time. HLA typing data is a crucial part of histocompatibility information, but the registry’s purpose is to hold the complete compatibility profile, not just the typing in isolation. Donor medical history matters for safety and eligibility, but it doesn’t drive the matching process in the same way. Recipient address and contact information are needed for logistics, not for assessing medical compatibility.
