Question: Are Siblings Always A Match For Bone Marrow?

Is it hard to find a bone marrow match?

Specifically, the matching process looks at markers, or proteins, known as human leukocyte antigens (HLAs).

A close HLA match is critical when transplanting blood and bone marrow–forming stem cells from an adult donor to a patient.

This makes it difficult for people of certain races or mixed ancestry to find a match..

What is a 10 10 HLA match?

Matching for the HLA-A, -B,- C,- DRB1 and -DQB1 loci is referred to as a 10/10 match, when HLA-DPB1 is included it becomes a 12/12 match. Matching for HLA-A, -B, -C, and -DRB1 loci is an 8/8 match.

Human Leukocyte Antigen Test (HLA) The HLA test looks at genetic markers on your white blood cells. If these markers are similar to those on the patient’s cells, you may be eligible to serve as a donor. You do not need to have the same blood type as the patient in order to be a donor.
