DKMS : How to become a stem cell donor?
How to become a stem cell donor?

You can also save lives!

Let's see the whole process

1. How do I register as a blood stem cell donor?

You can register in one of our campaigns or by completing our webform, after which a registration kit will arrive at your address. In this last case you only have to take the sample according to the instructions and send it back to us.

2. Who can register as a blood stem cell donor?

People who fill the following requirements can register: living in Chile, have good general health, be over 18 and under 55 years old and weigh more than 50 kg.

3. How do I know I am already registered as a donor in the base?

You will receive an email to welcome you to our donor registry. This means that your sample was analyzed correctly and your data is available for a possible search for someone who needs a transplant anywhere in the world.

How stem cell donations work

4. When will you call me for donating blood stem cells?

We may call you in a couple of months, in a few years or maybe never. The important thing is that being registered can give a second chance of life to someone who really needs it.

5. How a donation is performed?

In 80% of cases, the donation is made through the peripheral donation process, which lasts approximately 5 hours. In the other 20% of cases, the stem cells are removed from the pelvic bone in a procedure under general anesthesia.

6. Everything is clear. What should I do now?

Excellent! It is very important that you keep your data permanently updated, because if you result compatible with a person that requires a transplant, we will have to contact you as soon as possible.


Your decision to become a lifesaver

Various factors, including the health of the patient, determine whether you will be asked to donate your stem cells. If you are chosen, you should make a final decision regarding your commitment to the patient. After a final health check and consultation at the collection center, you will be asked to sign a consent form for the stem cell donation. The collection method (peripheral stem cell collection or bone marrow donation) is determined by the treating doctor and is dependent on both your health and the health of the patient. All expenses will be covered and DKMS is there to help every step of the way.

Approximately one week before your donation appointment, the patient will begin chemotherapy and sometimes radiotherapy, in order to prepare their body for the stem cell donation. At this point in time, withdrawing from the donation procedure would have life-threatening consequences for the patient.


How does it work:

PERIPHERAL DONATION For a period of 5 days, the donor will receive a G-CSF growth factor. This medication increases the number of stem cells in the bloodstream, which will be collected from the blood through a special procedure. The collection from the bloodstream lasts approximately 4 to 8 hours and can be done in one or two consecutive days. This procedure has been performed by DKMS since 1996. When you are having the medication, you may experience flu similar symptoms. According to research conducted to date, no long-term side effects are known.

EXTRACTION OF BONE MARROW Usually, two small incisions in the pelvic bone are enough. The collection is done with the donor lying on his stomach and lasts approximately 60 minutes. The risks envolved to this kind of donation are mostly limited to the complications of regular anesthesia. For a few days after collection, you may experience a localized pain similar to a bruise. The donor will stay in the hospital for two to three days after the bone marrow collection and then should be a few days at home to recover. To confirm, check with the hospital staff who will perform the collection procedure.


General anaesthetic is used for this method, in which a needle is inserted in the skin over the pelvic bone, in order to remove approximately one litre of liquid marrow containing blood stem cells. The process itself takes around one hour and a two night stay in hospital, meaning the donor can usually return to work within one week. With bone marrow collection, any risks are associated to the general anaesthetic rather than the collection itself. Donors may experience local pain from the procedure, but usually fully recover within one week with no long-term side effects. Furthermore, donors undergo a full health test before donation, to ensure they are healthy and able to donate.
