Complete blood count reference intervals for extremely preterm neonates.

ABSTRACT: Preterm infants exhibit dynamic hematological profiles during the first postnatal days, necessitating robust reference intervals for clinical interpretation. The aim of this study is to establish comprehensive reference intervals for complete blood counts in preterm neonates during the first five postnatal days, stratified by gestational age and postnatal age. Data from preterm neonates (23 + 0-34 + 0 weeks gestation) admitted to the neonatal intensive care unit Graz (2008-2023) were analyzed. Percentiles (2.5th, 10th, 50th, 90th, 97.5th) were generated for the following hematological parameters included in the full/complete and differential blood count (FBC, CBC): leukocytes, thrombocytes, hemoglobin, hematocrit, neutrophilic granulocytes, and lymphocytes.
