Pixtera - chances are your hematologist is just curious as to how your daughter is doing.
However since your hematologist has put doubt in your mind the best thing to do would be to talk to your pediatrician - get to the nitty gritty with her, tell her your concerns just as you have written above, ask her when/if your daughter should be tested.
As to bruises - any young child, older ones too for that matter, have bruises.
I used to have in my signature this quote:
-Instead of wasting your time worrying about symptoms, just get it checked out. -Nieca Goldberg, MD
Think that fits in your case too - no symptoms but the worry is there so talk to your pediatrician!
