After the donation

Long-term donor follow-up

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

Last updated: 18/07/2022

DKMS follows the general prescribed standards for follow-up of the World Marrow Donor Association (WMDA). The wellbeing of the donors has top priority at DKMS; we carry out an even closer follow-up than prescribed by WMDA.

The long-term donor follow-up programme is carried out by our Donor Follow-up Team.

After the first follow-up questionnaire, subsequent questionnaires will be sent out :

  • initially six months after your donation, 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.

You can also contact our team at any time outside of the follow-up sessions! They will be happy to answer your questions and help you further.

Frequently asked questions: Follow-up programme medical

Why and how often are my blood values checked?

After a stem cell donation, the body regenerates the stem cells within a few weeks. The follow-up programme includes checking blood values four weeks after donation to make sure that the relevant blood values have returned to normal.

Only if a blood value needs to be rechecked will we ask for additional blood tests.

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 a blood value needs to be rechecked will we ask for additional blood tests.
