We have measured by cation exchange high pressure liquid chromatography
adult hemoglobin (HbA) concentration at birth in 6,123 unselected single
newborn individuals. Probably because of the high precision of the
analytical method used, we could demonstrate clear a relationship between
HbA concentration and, respectively, gestational age and birth weight. We
also demonstrated a significant difference in the Hb switching process
between male and female newborns. Reference percentile distribution curves
are given that could be used to define more precisely those children having
slow or fast Hb switching.
