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.
吸入胎粪或被胎粪污染羊水的新生儿首次排出的尿液通常含有一种深色水溶性物质，通过在约405nm处的吸收带可进行分光光度法识别。通过这种方式，首次尿液的分光光度分析可用于诊断之前的胎粪吸入情况。
