HISTOLOGIC ASSESSMENT
Sections should be obtained as follows:
1. Cross section of umbilical cord
1b. Cross section just proximal to and just distal to any apparent cord constriction or cord stricture
2. Amniochorionic membrane roll
3. Fetal side placenta
4. Basal placenta
5. Sampling of any apparent abnormalities.
Reporting should include general description of each section and description (including severity and extent) of
