The Donation Process

The Donation Process

Why Donate?

Blood stem cell and marrow transplants are used to treat 70+ diseases, including blood cancers like leukemia and lymphoma, as well as sickle cell disease.

> 70% of patients do not have a matching donor in their family. They rely on an unrelated donor, someone like you, for their life-saving transplant. This is why we ask you to join the national registry.


1. Blood Stem Cell Donation/PBSC

The vast majority of transplants (80%) use a method called PBSC (peripheral blood stem cell) donation. It is a non-surgical procedure that is similar to donating plasma.

For 5 days leading up to the donation, you will receive an injection of filgrastim. This increases the number of blood-forming cells in your bloodstream (blood stem cells). Depending on where you live, you will visit a blood center, an outpatient hospital, or a visiting nurse will come to your home so that you can receive daily injections.

On the day of your PBSC donation, blood is removed through a needle in one arm and passed through a machine that will collect the blood-forming cells. The remaining blood is returned to you through a needle in the other arm. The process typically lasts 4-6 hours.

After the donation has completed, your stem cells are transported to the patient for transplant.

Are There Any Side Effects?  Some donors report muscle aches for a few days.

2. Bone Marrow Donation

The remaining 20% of donations are bone marrow donations. This is a surgical procedure, using anesthesia, that takes place in a hospital operating room. Doctors use a needle to withdraw liquid marrow (where the body’s blood-forming cells are made) from both sides of the back of your pelvic bone. Most donors go home on the same day.

After donation, your stem cells are transported to the patient for transplant.

Are There Any Side Effects?  Some donors report back or hip pain and fatigue for a few days after the procedure. Be the Match checks up on you until you report a full recovery.

Not Everyone is a Match

Not everyone on the Be The Match Registry® will match and be asked to donate to a patient. In fact, the chances of donating are 1 in 430. If you are asked to donate, the patient’s doctor has chosen you as the best donor.

If you are identified as a potential match for a patient, Be The Match representatives will work with you every step of the way. They cover every expense associated with the transplant process. Your comfort and safety are their priority.
