YOU can give a chance to live!

Since 2018, GenDx organizes an annual Stem Cell Donor Recruitment Day in the week preceding the World Marrow Donor Day. This initiative is established in cooperation with Matchis, the Dutch center for stem cell donors, and in line with GenDx’s mission to improve the quality of life and survival of transplant patients. Our main aim is to motivate as many young, fit people to register as a potential stem cell donor.

On Thursday 15 September 2022, we were present at various locations, mainly at Utrecht Science Park, but also in Leiden.

The results are in: 129 people registered using our event code, meaning that GenDx donates €4.515,- to Stichting Matchis!

A big ‘thank you’ to everyone who contributed to this year’s edition. Whether you helped with promoting the event, helped spreading awareness on the topic, or volunteered during the event… Together, we reached our goal, which was to motivate as many young, healthy people as possible to join the stem cell donor registry.

Onto next year…

Stay tuned!
