How do you get tested for bone marrow match?
When people join the Be The Match Registry, they provide a sample of their DNA by swabbing their cheek. This cheek swab is tested for a minimum of 6 basic HLA markers. A patient’s doctor will usually choose several donors who appear to match the patient at a basic level.
What is the criteria for a bone marrow match?
Doctors match donors to patients based on their human leukocyte antigen (HLA) tissue type. HLA are proteins, or markers, found on most cells in your body. Your immune system uses these markers to recognize which cells belong in your body and which do not.
What are the chances of matching bone marrow?
A patient’s likelihood of finding a matching bone marrow donor or cord blood unit on the Be The Match Registry® ranges from 29% to 79% depending on ethnic background.
Does bone marrow have to be an exact match?
The HLA must be as closely matched as possible so that the transplant recipient’s body can ‘accept’ the new stem cells into their bone marrow. Just as important, matching at HLA will decrease the chance of the new marrow reacting against the patient, a reaction called graft versus host disease.
How long does it take to find out if you are a bone marrow match?
After any testing stage, it may take up to 60 days for the patient’s doctor to review the results, select a donor and decide to move forward with a transplant. If you have questions about the donation process you can find answers in Donation FAQs or call 1 (800) MARROW-2 to speak to a Be The Match representative.

How do you test for bone marrow compatibility?
From a blood test. Typically a bone marrow or stem cell match is determined from a blood test. The test measures your ’tissue type’ by looking at the hla proteins on the surface of your cells.
What should I know about having a bone marrow test?
The steps of a bone marrow biopsy are usually as follows: Before the biopsy, the person under examination changes into a gown. The healthcare provider applies an anesthetic with a needle to numb the biopsy area. Once the biopsy site is numb, the healthcare provider makes a small incision at the biopsy site. After the aspiration comes the bone marrow biopsy.
What does my bone marrow biopsy report suggest?
The biopsy allows us to see the architecture of the bone, the outer dense bone, and the inner “spongy” marrow, as well as all the cells in the spongy space of the marrow. The cells in the spongy space are normally surrounded by fat, and when the bone marrow report indicates the “cellularity” this refers to the amount of the space that has cells in it; the remainder is fat .
What should I know about bone marrow biopsy?
Your doctor may order a bone marrow biopsy if your blood tests show your levels of platelets, or white or red blood cells are too high or too low. A biopsy will help determine the cause of these abnormalities, which can include: anemia, or a low red blood cell count.
