Abstract
Zinc coproporphyrin, isomers I and III (I:III ratio, approximately 8:1), was identified in human meconium using high-performance liquid chromatography, ultraviolet-visible absorbance spectroscopy, and emission fluorescence spectroscopy. The high levels of zinc coproporphyrin in the first stools of life decrease steadily as meconium is evacuated and reach a plateau at comparatively negligible levels after complete evacuation of meconium. Zinc coproporphyrin can be used as a marker for human meconium.
