The inclusion of donor date of birth or donor initials alongside the UNOS ID provides an additional layer of identification that enhances both safety and traceability in tissue typing. Accurate labeling is critical in transplantation to prevent errors and ensure that the right tissues are matched to the right recipients.

Using the donor date of birth helps to confirm the donor's identity and allows for better differentiation between donors, which is particularly useful in situations where multiple donors may have similar or identical identifiers. Donor initials can serve as a quick reference point for healthcare providers, contributing to seamless communication and record-keeping.

In contrast, relying solely on the UNOS ID may not be sufficient, as this unique identifier alone does not provide contextual information that can be vital during the handling of tissues. The other options suggest using identifiers that either do not add meaningful differentiation or are limited in scope compared to the broader utility of including both the donor date of birth and initials.
