New study aims to uncover cause of blood in newborn stool
NCT ID NCT06088537
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 40 newborns with isolated rectal bleeding to see how many have a cow's milk protein allergy versus a temporary condition called transient neonatal colitis. By removing and then reintroducing cow's milk from the diet, doctors can confirm an allergy if bleeding stops and returns. The goal is to better understand these conditions and improve diagnosis.
