Your granulocyte count can be determined with a complete blood count (CBC). There are two ways of doing this: ablative (myeloablative) treatment and reduced intensity treatment, or a mini-transplant. A person with cancer usually undergoes chemotherapy before transplantation. Healthy bone marrow is an essential part of the body, as it contains stem cells that produce blood cells and the cells that make up the immune system. Inappropriately high levels of erythropoietin can cause high levels of red blood cells. These allow the cell to attach to an antigen on the surface of an invading microbe or another antigenic agent.

They can reproduce another cell identical to themselves, and they can generate one or more subsets of more mature cells. Granulocytes form in the bone marrow and release into the bloodstream when necessary. Monocytes are produced in bone marrow. These cells are so-called because they mature in the thymus, which is a small organ in the upper chest, just behind the sternum. In adults, the highest concentration of red bone marrow is in the bones of the vertebrae, hips (ilium), breastbone (sternum), ribs, and skull, as well as at the metaphyseal and epiphyseal ends of the long bones of the arm (humerus) and leg (femur and tibia).
