So much we can learn!

Biological samples allow scientists to open up a little window into how the body works. We will collect blood and hair samples at our in-person visits. We will also ask you to collect stool and vaginal swab samples from yourself, and stool and nail samples from your child. We will provide you with a kit at your first in-person visit. Please collect your mom stool and vaginal swab sample within the dates specified on your kit.
