The ADVANCE Study is looking at a new way to check a developing baby's health using a test called circulating fetal cell (CFC) assay. This test is special because it uses cells from the baby's placenta found in the mother's blood, so there's no need for risky procedures. These fetal cells are mainly found in the early part of pregnancy. Researchers have created a test, called UNITY Confirm, that looks at these cells to check the baby's chromosomes, which are important for its development.

This study involves pregnant people between 10 and 20 weeks along with one baby. It plans to include more than 1,000 participants and compares the results of CFC testing with other tests done before or after the baby is born. If you are pregnant and healthy, you might be able to join.

• Who can join? Pregnant individuals 10-20 weeks with one baby.
• What it involves: Blood test to check baby's health.
• Who can't join? Those with active cancer.
