Understanding Meconium
Meconium is a newborn baby's first stool, and it contains valuable information about what happened during pregnancy. Unlike regular stool, meconium begins forming in the intestines while the baby is still in the womb.
This dark, sticky substance contains materials the baby ingested while in the uterus, including intestinal cells, lanugo (fine body hair), mucus, amniotic fluid, bile, and water. Because it forms during pregnancy, meconium essentially creates a record of substances the baby was exposed to before birth.
Dr. Ostrea realized that analyzing meconium could reveal exposure to harmful substances that might not show up in other tests, making it an invaluable diagnostic tool.
