Preimplantation genetic testing
Preimplantation genetic diagnosis (PGD) is a way of checking embryo cells before they are placed, or implanted, inside a mother's body. It is also named preimplantation genetic testing (PGT). The good thing about PGD is that it can let the parents not choose the embryo which will develop into a child with a certain disease. This way, the parents do not have to choose to stop the pregnancy if the baby has the disease. To do preimplantation testing, doctors take the mother's eggs from her body. Then, the embryo is tested, and put back in the mother after 5 or 6 days of growing.
