 On Days -10, -1, 0, 1, 3, 7, 14, 21, and then at 1, 2, 3, 6, and 12 months after the transplant, blood about 3 tablespoons will be drawn to check your immune function, response to the T cells, inflammatory responses, and for GVHD markers. If possible, the blood will be collected during standard of care blood draws so that no additional needle sticks will be needed.
