title: Health term-born girls had higher levels of urine neutrophil gelatinase-associated lipocalin than boys during the first postnatal days.
abstract: Neutrophil gelatinase-associated lipocalin (NGAL) is one of the most extensively examined biological markers for early prediction of acute kidney injury, but there is a lack of data on normal NGAL values in healthy term-born infants. This encouraged us to established serum and urine levels using samples collected from 38 girls and 50 boys, born at a median age of 39 weeks, during the first 48 hours after birth.
  
  
  CONCLUSIONS
  Our findings showed that urine NGAL, but not serum levels, were significantly higher in girls than in boys.
