Follow up every year with your child’s hematologist if they have HPFH. — Reviewed: August 2024 TīmeklisFetal hemoglobin binds to oxygen more strongly than adult hemoglobin, enabling the transfer of oxygen from mother to fetus prenatally. Oxygen exchange within the tissue is thus affected by the strength of the binding between hemoglobin and oxygen.
