The sample might be taken transcervically or through the abdominal wall (transabdominal). The placenta eliminates waste from the baby’s blood while also supplying oxygen and nutrition to the developing fetus. The wispy placental tissue protrusions known as chorionic villi are genetically identical to the developing infant. As early as 10 weeks of pregnancy can be used for the test.
