The ZKRD only receives pseudonymized data relating to donors. Therefore, we have no
access to your personal data. Please contact “your” donor center in this respect. If you no
longer know which donor center this is, you can refer to your donor card. Unfortunately, you
will have to contact every single donor center if you do not have such a card. The best
approach would be to start with the donor center nearest the facility where typing was
performed.
