Unit Exclusion Label

There may be circumstances where a donor may not answer the Record of Donation questionnaire truthfully. In some cases, owing to the personal nature of the questions, a donor may be uncomfortable with providing certain pieces of information. In other cases, donors may be reluctant to tell friends, family or colleagues that they have been deferred—and thus continue with the donation to avoid answering uncomfortable questions.

To guard against such situations, the Canadian Blood Services employee provides the donor with two bar-coded labels. One indicates that the donor’s blood can be used and the other asks that the blood not be used. Once the appropriate label has been placed on the Record of Donation, no one at the clinic can determine which one was chosen. It is only later, in the laboratory, that a technician will scan the label with a bar-code reader before the unit is processed to determine whether or not it may be used.
