What makes a bone marrow match?

How is a bone marrow match determined? Doctors look for a donor who matches their patient’s tissue type, specifically their human leukocyte antigen (HLA) tissue type. HLAs are proteins — or markers — found on most cells in your body.

Are family members the best bone marrow donors?

The optimal donor is a histocompatible (HLA) matched relative who is usually a sibling or, in rare cases, a parent or grandparent with identical HLA tissue typing. Everyone inherits two sets of chromosomes containing HLA genes, four genes per set.

What does being a bone marrow donor involve?

Bone marrow donation is a surgical procedure that takes place in a hospital operating room.

Who is the best donor for bone marrow transplant?

A matched sibling turns out to be the best donors of bone marrow among all other options because it gives more chances of successful transplant being the closest possible match. It helps in quick engrafting of the donor cells and in turn, boosts the body for new blood cell formation once again.
