Donors are typically required to give consent for the process and this requirement means that minors cannot donate without parental consent.[15] In some countries, answers are associated with the donor's blood, but not name, to provide anonymity; in others, such as the United States, names are kept to create lists of ineligible donors.[16] If a potential donor does not meet these criteria, they are deferred. This term is used because many donors that are ineligible may be allowed to donate later.
The donor's race or ethnic background is sometimes important since certain blood types, especially rare ones, are more common in certain ethnic groups.[17] Historically, donors were segregated or excluded on race, religion, or ethnicity, but this is no longer a standard practice.[18]
