Routine hematological values in term newborns.

Routine hematological parameters were investigated in 240 term normal neonates, 40 neonates in the first week of life and 49 infants between 3 and 6 months of age. Term normal neonates were selected on the basis of well defined criteria. Cord blood Hb values of 16.2 +/- 1.5 g/dl compared well with some of the recent Indian studies and Caucasian figures. Cord blood hemoglobin was lower in the presence of low maternal hemoglobin and in newborns delivered by Cesarean section. A wide variation existed in the total and differential leucocyte counts, thus limiting the clinical utility of white cell counts in the newborn period. Platelet counts were within the adult normal range.
