Faecal S100A12 concentrations in 56 healthy infants and children. Serial stools collected from the first day of life (meconium) to 6 months of age from 7 healthy infants (Population 1) and single stools collected from 49 children (Population 2) were utilised to measure faecal S100A12 concentrations by immunoassay.
