Dani,
Glad she got it checked out. Also since her WBC is down yoou need to have a thermoneter around at all times. I even carry one in my purse. If her temp reaches 100.5 you need to call the doctor for instructions. This will help catches any infections early.
They can also give her Neupigen (sp)shots to build her WBC up, but they will wait a bit to see if her body will do it alone first.
Good luck and take care,
Dinah
