You are needed!

Join the Tobias Registry and get the opportunity to save someone’s life!
Every day, someone is affected by a life-threatening blood disorder that can be treated with healthy blood stem cells when nothing else works. But for donation to be possible, a perfect match between patient and donor is needed. And it could be you, just you in the whole world, who is the perfect match.

Joining the registry is easy. When you take a swab, we can identify your unique HLA type and match you with a patient who are in need of a donor. But about 30% of everyone who need healthy blood stem cells never find a suitable donor. That is why we need more people to join the Tobias Registry. Many more.

You can be the only one for someone.

Take a swab from yourself

Once the health declaration is completed and approved, we will send you a swabbing kit. You swab the inside of your cheek and send the swab back to us.

The swabs are analysed to obtain your unique HLA type, which is stored in a secure database and this is the value which is then used for matching patients with.


You are now in the Tobias Registry!

By joining the registry, you are searchable by patients worldwide. Should you match with a patient, we will contact you about the next steps.

Not everyone on the Tobias Registry will have the chance to donate stem cells. Being on the registry is important because each member of the registry increases the chances of finding suitable donors for all patients.

Blood producing stem cells are found inside the bone marrow. If you become a candidate for donation, there are two ways to collect stem cells, either via the blood (peripheral stem cell harvest) or directly from the bone marrow (bone marrow harvest). The most common collection method is via the blood.
