| pubmed-article:626523 | pubmed:abstractText | The first urine passed by a newborn infant who has inhaled meconium or meconium-stained amniotic fluid often contains a dark-coloured water-soluble substance, recognisable spectrophotometrically by an absorption band at about 405 nm. Spectrophotometric analysis of the first urine can in this way be used to diagnose preceding meconium aspiration. | lld:pubmed |
