OneBlood says it has found three matches so far, one near London and two in the US, but she will need blood transfusions for the foreseeable future, which means more donors must be found.
As per the details mentioned by Zainab's family and her doctors, donors must be of Pakistani, Indian, or Iranian lineage. Narrowing the field further is the fact that donors would also need to be missing the "Indian B" antigen commonly found in blood, just like Zainab.
Locating people who are missing the Indian B antigen comes down to genetics.
OneBlood runs blood donor centers across the Southeast.
Must be blood type "O" or "A".

Zainab's tumor was found in her stomach two months ago, but doctors believe it may have been growing undetected for nearly ten months.More news: Travis Scott Denies Cheating On Kylie Jenner: 'Try Again,' Trolls

"We were all crying", Raheel Mughal, the girl's father, said, according to the Miami Herald. 'This was the worst thing we were expecting'.
Zainab will need up to seven more people to donate throughout the course of her treatment, according to the organization.
So far, at least three donors have been found, two in the United Kingdom and one in the U.S. In about 2 out of 3 cases, the cancer has already spread to the lymph nodes or other parts of the body upon diagnosis.
The two-year-old from South Florida, Zainab suffers from Neuroblastoma, a cancer that grows from immature nerve cells surrounding the adrenal glands that affects children of five years of age or under.
Statistically, donors need to be exclusively of Pakistani, Indian or Iranian descent.
'We need to find more.It's a humble request, and I request it from my heart, ' said Raheel Mughal said in the video. And more than 1,000 people who are of Iranian, Indian or Pakistani descent have donated blood to be tested, Forbes said.
"What you're doing to save a human life, my daughter's life, is unbelievable", shared Mughal.
