Blood cells are made in the bone marrow, but most blood cell problems in lupus occur after the cells leave the marrow and enter the blood stream. Thus, most hematological questions in lupus can be answered from the results of blood tests alone. Occasionally, however, a bone marrow test provides important information to help in planning treatment.
