| Collection ID: | CO001762 |
| Collection Summary: | The study includes archived biological samples collected during pregnancy (maternal blood, urine, and hair), birth (infant cord blood, placenta, and meconium), and childhood (urine, blood, buccal cells, breast milk, toenails, and stool), and further health outcomes are being assessed through DNA methylation arrays, gene expression, microbiome sequencing, metabolomics and flow cytometry of these samples. Breast milk samples were collected at home by study participants from unsterilized bilateral breasts, with separate study-provided sterile collection bottles used for milk from each breast. To capture a representative portrait of infant exposure during breastfeeding we did not use a sterile collection protocol. Subjects provided a minimum of 18 mL and up to 80 mL of milk from each breast, with a median of 35 mL per breast. Samples were stored in the refrigerator at participants homes for up to approximately 1 day, brought in cold packs to the postpartum follow-up appointment (between 3.7 and 12 weeks after delivery), and immediately chilled. Samples were processed within 24 h of receipt. Samples were stored at -80C until analysis |
