University of Wisconsin at Madison scientists report they have found elevated levels of hemoglobin F (fetal) in the blood of infants whose cause of death was listed as SIDS.
They suggest that "infants with SIDSare characterized by a marked delay in the switch from hemoglobin F to hemoglobin A -- a phenomenon that may reflect an underlying chronic condition.
