my 9 year old daughter has a consistent low wbc (3.4), GR (33.6), GR# (1.1), MPV (7.4), MCH (32.6), and LY (62.1). She bruises easily, and scars tend to heal slowly.Can you please tell me what this could be? She is 54 inches tall and weighs approx 64 lbs. She also has had a significant amount of hair loss over the past year.
