This study is collecting blood samples from pregnant women who have RhD negative blood. The goal is to help develop better non-invasive prenatal tests (NIPTs) that can tell a baby's Rh blood type from the mother's blood during pregnancy. You can join if you are at least 18 years old, are between 12 and 28 weeks pregnant with one baby, and have RhD negative blood. Researchers will collect your blood and then record your baby's RhD blood type after birth. The main goal is to see if they can accurately determine the baby's RhD type from your blood sample, with results expected 18 months after the study begins. The study is currently unclear on its recruitment status and plans to enroll 500 participants.
