Serum Neuron-specific Enolase Levels in Preterm and Term Newborns and in Infants 1–3 Months of Age
Elevated serum levels of neuron-specific enolase (NSE) was initially assumed to be specific to neuronal tumors (particularly neuroblastoma), but is now known to accompany nontumoral conditions and tumors other than neuroblastomas. There is a need to establish normal ranges for NSE, especially in ear...

Methods: We enrolled 140 healthy babies, which included 40 preterm newborns (3–15 days old and born at 28–42 weeks gestation), 40 term newborns (< 1 month old and born at term), and 60 young infants 1–3 months old (n = 20 per subgroup of 1-, 2-, and 3-month-old infants).

The mean serum NSE levels for the preterm newborns was 21.83 ± 15.06 ng/mL [95% confidence interval (95%CI), 16.95–26.71 ng/mL]; term newborns, 18.06 ± 12.83 ng/mL (95%CI, 13.94–22.19 ng/mL); and young infants, 9.09 ± 4.38 ng/mL (95%CI, 7.96–10.23 ng/mL). The mean serum NSE level for infants 1–3 months old was within the ECLIA kit's normal range (4.7–18 ng/mL for adults), whereas the corresponding means for the preterm and term newborns were higher (p < 0.001, for both).
