You will have an electrocardiogram (ECG -- a test that measures the electrical activity of the heart). You will have a bone marrow aspirate and biopsy performed. To collect a bone marrow aspirate and biopsy, an area of the hip or chest bone is numbed with anesthetic, and a small amount of bone marrow and bone is withdrawn through a large needle. Women who are able to have children must have a negative blood or urine pregnancy test.
