Which factor is used for matching organ recipients by size?

• A. Size matching
• B. Recipient's eye color
• C. Blood pressure
• D. Donor's age

Answer: (A)

Size matching is essential in organ transplantation because the graft must fit the recipient's anatomy and connect properly to blood vessels and ducts. When the donor organ is proportionate to the recipient's body size, perfusion and function are more likely to meet metabolic demands and avoid vascular or anastomotic issues. Eye color is not a factor in organ size decisions; blood pressure is important for overall perioperative management but does not determine size compatibility, and donor age can affect graft quality but not the physical fit. Therefore, the factor used for matching organ recipients by size is size matching.
