Transgender is an umbrella term for individuals whose gender identity (includes genders outside of the male/female binary) differs from their sex assigned at birth. Some reported that the gender on the donor's identification determined the Hgb threshold, while others used the donor's self-reported gender or the donor's sex at birth. Questions included how donor gender is ascertained if a donor's recorded gender can be changed, how eligibility criteria are assessed in transgender donors and how non-binary donors are managed. This international survey identified significant variation in approaches to determine the sex/gender of a potential donor, including the process for allowing a donor to change gender and policies to address transgender donors, including those who identify as non-binary.
