Blood disorder?

My sister, the only sibling I have, was hospitalised for an aparent blood deficiency. She has 2 small boys, who love their mother dearly, and she provides for them the best that she can. She is currently under the great (and super expensive) care of St. Luke's medical center, and will be residing there for hopefully a short period of time...but until the doctors can really get a grasp on the root cause, the entire family is left in limbo. Asking for any donations to help offset the medical bills that have and continue to accrue, as well as the time and wages she is losing from work. She works full time and rent isn't always easy to make on a single income...let alone when the income isn't coming in. Every little bit helps, thank you all for taking the time and for any donations you are able to make.
