FABP2 and necrotizing enterocolitis: The median concentrations of serum I-FABP and FC were significantly higher in infants with suspected NEC (4.76 μg/mL and 521.56 μg/g, respectively) than in control subjects (1.38 ng/mL and 213.34 μg/g, respectively), despite similar postnatal ages (p < 0.05 for both).
