After the donation

Long-term donor follow-up

All further donor follow-up will be through DKMS. Blood tests are usually no longer necessary.

We will send you a short questionnaire about your health and general condition - for the first time six months after your donation and then once a year until ten years have passed. The DKMS team check the questionnaires very carefully and will contact you immediately if there is a need for any extra clarification.

Of course, you can also contact one of our team at any time outside of the follow-up sessions! They will be happy to answer your questions and help you further. If you have any questions, please send an email to or alternatively, give us a call on 0800 12 10 82. Lines are open Monday – Friday, 08:30 to 16:30.

Frequently asked question follow up

What examinations are due after stem cell donation?

After your stem cell donation, we ask you to take part in a donor follow-up. This helps us to keep a close eye on your well-being. The first donor follow-up takes place four weeks after your stem cell donation. To find out more please read the information within our donor follow up monitoring.

Why does the follow-up take so long?

DKMS is subject to the general prescribed standards for follow-up of the Central Bone Marrow Donor Registry Germany (ZKRD). Because the well-being of the donors has top priority at DKMS, we carry out an even closer follow-up than prescribed.

Why are my blood values checked?

After a stem cell donation, the body regenerates the stem cells within a few weeks. The purpose of checking blood values four weeks after donation is to make sure that the relevant blood values have returned to normal.

How often do I have to have blood samples taken after donation?

Normally, a blood sample only needs to be taken once - four weeks after donation. Only in the case that blood values still need to be checked, the collection clinic will ask you for another control blood sample.

Please return the first questionnaire that you receive from the collection clinic after your stem cell donation to the collection centre.

Please send all further questionnaires for follow-up after six months after your donation to the DKMS Physicians Team.

Will I receive feedback after each questionnaire?

No, you will not receive feedback after each questionnaire, but only if there is a need for clarification. Of course, you can contact our team of doctors at any time - even independently of the donor follow-up!

When will I be contacted by the DKMS after my donation?

In addition, we will send you a questionnaire as part of the donor follow-up six months after your donation for the first time and then once a year until ten years have passed since your donation.
