News outlets report the woman had stored her own blood while pregnant in case she needed a transfusion during her delivery. The blood wasn't needed and the woman agreed to give it to Zainab Mughal, who has neuroblastoma.
Susan Forbes of Florida-based OneBlood says the woman isn't eligible to donate more so soon after giving birth. The blood center is seeking more donors for the girl, who lacks a feature common to most types of blood. The donor must be of Pakistani, Indian or Iranian descent and have type A or O blood.
