title: Neonatal Th activation.
abstract: A case is reported of a 1-month-old infant with bowel obstruction and suspected sepsis whose red cells were found to be Th activated during the course of evaluating weakened A antigen activity. Neither Th activation nor weakened A antigen activity was present on the red cells of either parent. The Th activation and the weak reactivity obtained with commercial anti-A reagents were unrelated.
