Abstract
Summary
1. The blood-group-specific substances present in meconium from a series of 53 infants were found to correspond to the blood type of the baby and its ability to secrete blood group material in its saliva in all except 2 cases in which O activity was demonstrated in the meconium but could not be found in the saliva. 2. The meconiums of blood groups A and B were more active than those of groups AB or O. 3. No M or N activity could be demonstrated in meconium. 4. The blood-group-specific substances in amniotic fluid corresponded with the blood type of the baby and not that of the mother.
