Samples
What types of samples will you collect?
The researchers doing this study will be doing tests on biological samples that will help them understand the health and development of your baby and its placenta during pregnancy, along with any exposures to substances they may have experienced during pregnancy. All biological samples collected during this study will be used only for these purposes.
Umbilical Tissue Collection:
After delivery, a 6 inch section of the umbilical cord will be collected and flash frozen. This will be sent to NMS labs for broad spectrum drug screening and analysis of substance exposure.

Placenta Examination and Tissue Collection:
After delivery, samples will be taken from your placenta. Study staff will collect and freeze 10 pieces of tissue (0.5cm cubed each) from 5 different locations. An additional 2 pieces of tissue will then be taken and preserved in wax blocks. The frozen samples and wax preserved samples will be sent to the Placenta Lab for testing and future use related to the study.
