- A bone marrow aspiration can take about 60 minutes. Bone marrow is the spongy tissue inside your bones. It’s home to blood vessels and stem cells that help produce: red and white blood cells platelets fat, cartilage, bone.
- There are two types of marrow: red and yellow. Red marrow is mainly found in your flat bones such as your hip and vertebrae. As you age, more of your marrow becomes yellow due to an increase in fat cells. Your doctor will extract red marrow, usually from the back of your hip bone. And the sample will be used to check for any blood cell abnormalities.
