How To Become A Bone Marrow Donor

Do you worry about the welfare of other people? You hate seeing sick people, especially those with sickle cell anemia or leukemia. Do you regularly see a doctor and stay in excellent health?

If you’re concerned about how to become a bone marrow donor, we have the best step-by-step guidelines.

Being a bone marrow donor offers several advantages, including giving a sick person a second chance at life and reviving hope in the face of medical situations that appear insurmountably dismal.

A successful bone marrow transplant requires a good match between the donor and the recipient. It is more difficult to match bone marrow stem cells than to compare blood types.

You will also have your human leukocyte antigen (HLA) tested to see whether you might be a bone marrow match.

Most body cells, including immune system cells, contain the protein HLA. An HLA match increases the possibility of a successful bone marrow transplant.

What is a Bone Marrow?

Bone marrow is a soft, spongy tissue that can be found in the medullary cavities of various large bones (centers).

Bone marrow is an essential part of the body because it contains stem cells that develop into the cells of the immune system and those that make up blood cells.

What is a Bone Marrow Transplant?

A bone marrow transplant is a medical procedure that uses healthy blood-forming stem cells to replace bone marrow that isn’t producing enough healthy blood cells.

Few Things to Know about being a Bone Marrow Donor

You should know these things before choosing to be a bone marrow donor:

The Importance of Bone Marrow Transplants

Bone marrow transplants can be used to treat a variety of diseases and malignancies.

If the chemotherapy or radiation doses required to treat a patient’s cancer are so severe that the therapy may permanently damage or destroy the patient’s bone marrow stem cells, a bone marrow transplant may be necessary.

Transplantation of the bone marrow’s damaged tissue can also be necessary.

How many times can Bone Marrow be Donated?

You can give it more than once since your body can replenish lost bone marrow.

Although registering as a donor does not guarantee that you will be matched with a recipient. It’s unusual to find many matches.

What Medical Conditions are Bone Marrow Donors needed?

Bone marrow transplants may be helpful for people with leukemias, severe aplastic anemia, lymphomas, multiple myeloma, immune deficiency syndromes, and various solid tumor malignancies.

How are Donations and Recipients Matched?

HLA-A, HLA-B, HLA-C, and HLA-DRB1 specific antigens are necessary for successful marrow and cord blood transplantation (also called BMT).

These antigens are used to “match” a donor and patient. Antigens are proteins that cover the outside of white blood cells and other bodily tissue.

When seeking for a partner, people of the same race and ethnicity are more likely to complement one another.

Types of Bone Marrow Transplant

Bone marrow transplants come in two main categories. both allograft-based bone marrow transplants and autologous transplants. Whichever is best for the patient will be determined by the physician.

Autologous Transplant:

Autologous transplants involve the utilization of a patient’s stem cells. They frequently demand collecting a sample of your cells before beginning a cell-damaging therapy like chemotherapy or radiation. After the treatment, your body gets your cells back.

This type of transplant does not always have options. If the bone marrow is healthy, it can only be used. However, it lessens the likelihood of serious adverse effects like GVHD.

Bone Marrow Transplant using an Allograft

The genetic makeup of the patient and the donor is identical. Through bone marrow harvest or apheresis, a genetically compatible donor—typically a brother or sister—provides stem cells.

Various bone marrow transplants may serve as additional allogeneic bone marrow donors (BMT or MUD for matched unrelated donors).

Benefits and Drawbacks of being a Bone Marrow Donor


  1. If the patient has immunological deficits, a donation from a potent immune body can help the patient’s immune system develop.
  2. This approach can be used to treat both acute and chronic leukemia.
  3. Bone marrow transplants help ensure the safe administration of chemotherapy doses by replacing damaged bone marrow following treatment.
  4. It helps treat a variety of illnesses, including leukemia, immunological deficits, and inherited metabolic issues.
  5. Transplanting bone marrow helps to provide newly formed stem cells, which are essential for eliminating cancer cells.


  1. Both the patient and the donor experience mild short- and long-term negative effects following the transplant. Nausea and vomiting, mouth sores or ulcers, infections, bleeding, anemia, exhaustion, and many other symptoms could be present on either side.
  2. One concern is harm to the organs. The possibility of effects changes is somewhat alarming.
  3. After a bone marrow transplant, complications from an allogeneic transplant could lead to graft versus host disease.

How to Become a Bone Marrow Donor

There are various steps involved on how to become a bone marrow donor or peripheral blood stem cell (PBSC) donor.

In order to ensure that the donor and recipient are the best possible matches and that the donor is in good enough health to contribute, processes have been put in place.

The following are the steps on how to become a bone marrow donor:

Bone Marrow Registry

A bone marrow registry might help the 70% of people who don’t have a family who is a good match find one. BeTheMatch is the name of the biggest donation registry. It creates a database of potential bone marrow donors and registers such individuals. The registry will then be used by doctors to locate a compatible donor for a patient in need of a bone marrow transplant.

How to Join Bone Marrow Registries

Anyone who meets the following criteria will be added to a bone marrow donor registry:

  • Between 18 and 60 years old
  • Healthy, not pregnant

Online or in-person donor registry drives are available for registration. The required age range to sign up is 45 to 60. Only donors under the age of 45 are accepted at the regional, in-person campaigns. Compared to stem cells from older persons, their stem cells are more likely to benefit patients.

Those that register are required to:

  • Take a sample of cells from the inside of their cheek using a cotton swab.
  • Give a tiny sample of blood (about 1 tablespoon or 15 milliliters)

The blood or cells are then examined for certain proteins known as human leukocyte antigens (HLA). Your immune system, which fights infections, can differentiate between substances from your own body and foreign substances with the aid of HLAs.

Frequently Asked Questions

How often can you donate bone marrow?

Depending on your lifetime, you might only ever receive one or two calls about potential matches. You can still donate to someone else if the need arises after you've already done so for someone else. Furthermore, should you ever require a transplant, it has no impact on your capacity to get one.

How much weight must you be to donate bone marrow?

LThere is no prerequisite for a certain weight. There are, however, BMI restrictions for bone marrow donation. To assist protect your safety as a donor, some rules have been developed. In the event that you are asked to donate, you will first undergo a health checkup and physical examination.

What risks are associated with bone marrow donation?

The use of anesthetic during surgery and its consequences pose the greatest risk connected with bone marrow donation. Weakness, fatigue, and little back or hip pain could all be side effects of the procedure. Acetaminophen (Tylenol, among others) or ibuprofen (Advil, Motrin IB, among others) are two painkillers that may be helpful.

Does getting a Bone Marrow Painful?

A local anesthetic can be used to numb the area where the needles will be put during a bone marrow test. Particularly during bone marrow aspiration under local anesthetic, pain may be fleeting but intense. Many folks choose for minor sedation in addition to painkillers.
