Journal of Pediatric Hematology/Oncology: March 2019 - Volume 41 - Issue 2 - p e119-e121 doi: 10.1097/MPH.0000000000001164 Buy Metrics Abstract Red cell distribution width (RDW) is altered because of prematurity and fetal growth restriction (FGR). We conducted a prospective observational study to determine normal RDW values in Indian neonates (N=964) with significant FGR. Mean RDW values in preterm neonates were higher than term neonates (P<0.0004). The RDW values in Indian neonates (with significant FGR) were higher than their western counterparts (P<0.0001). The mean RDW values for different gestational ages in Indian neonates are higher than those observed in other studies. This could be attributable to the FGR component among Indian neonates.
