Blood tests (between 100 - 120 cc) marrow sampling, and x-rays will be done as needed to track the effects of the transplant. For bone marrow sampling, a large needle is placed into the numbed hipbone. The bone marrow is then withdrawn through the needle. Patients will have transfusions of blood and platelets as needed. Blood tests (between 100 - 120 cc) will be done daily while patients are in the hospital.
