Selecting the Right Donors - Still a Challenge: Development of a Uniform Donor Questionnaire in Germany.

The selection of blood donors includes the assessment of the individual's health and medical history by using a donor questionnaire (DQ) in order to identify persons whose donation could present a health risk to recipients or to themselves. This way, DQs provide one layer of blood safety and contribute to the high safety profile of blood components currently available in Germany. This review reports the development of a new uniform questionnaire in Germany and its first evaluation using a field test approach. This development is set in context with the international experiences regarding donor selection and prospective challenges.
