Newborn infants, whether born at term or very preterm have peripheral blood neutrophil counts very similar to older children and adults

Mature neutrophils are first detected by 14 to 16 weeks of gestation, but at mid-gestation the numbers of postmitotic neutrophils in the fetal liver and bone marrow remain markedly lower than in term newborns and adults.
