There is no discomfort. Some diapers contain antibacterials, therefore it is recommended that the diaper be lined with clear plastic wrap to protect the specimen and ensure accurate results. It is composed of amniotic fluid , salts, bile , cells, and normally is free of bacteria. While bacteria in the gut are a common and necessary part of life after birth, life in utero is normally sterile, and therefore there are no organisms in the meconium. If your child has been exposed to infected amniotic fluid, then this test may be positive for infective organisms and indicate the need for intervention and close attention.
Normal values show no organisms in the meconium stool of the newborn.
This is of concern since the infant immune system is underdeveloped and unprepared for an onslaught of invading organisms. Therefore a newborn infection could lead to newborn sepsis .
