OneBlood says it has found three matches so far, one near London and two in the USA, but she will need blood transfusions for the foreseeable future, which means more donors must be found. They weren't. A parade of family and friends came into the hospital to be pricked by needles.
Florida-based OneBlood, a nonprofit blood center, has now been conducting an worldwide search to find compatible blood donors.
Zainab Mughal, 2, is sick and needs a blood donor with the same rare blood she has.
"We have a zero per cent chance of finding compatible blood for this little girl if we look in pretty much any other ethnic group", said Ms Bright.
But a small percentage of people - including Zainab - produce antibodies in the presence or absence of certain antigens, prompting the body to reject the blood.
Zainab's tumor was found in her stomach two months ago, but doctors believe it may have been growing undetected for nearly ten months. In addition, the donor must also lack a common antigen carried in red blood cells called "Indian B".
Doctors told her parents the tumor in the two-year-old's abdomen had been growing for almost half of her life and would need rapid and involved treatment, including two bone marrow transplants, chemotherapy and a series of blood transfusions.
Donors need to be exclusively of Pakistani, Indian or Iranian descent, meaning both parents must be 100 percent of one of these ethnicities.
'We were all crying, ' said Zainab's father Raheel Mughal in an interview with OneBlood. "We are searching the world to try to find blood for this little girl".
Thus far, three donors have been found, two from the United States and one from England, but Zainab will need more blood than they can provide. For the majority of people, getting the blood type right is all that matters.
"Rare blood is the blood that you don't have when you need it no matter what", Nance said.
But doctors are saying that the seriousness of Zainab's treatment means they'll need at least seven more. Still, Zainab's case is so rare that Bright - who's worked in the industry for 20 years - had to go to a textbook to learn more about it.
In OneBlood video, Mughal made a plea for those who can help.
'My daughter's life very much depends on the blood.
