Preimplantation genetic diagnosis (PGD) for single gene disorders is a powerful genetic test that may be performed during IVF treatment to screen embryos that are at risk to develop a serious genetic disorder. PGD is performed on a small embryo biopsy and identifies which embryos are not at increased risk of developing the disease. The goal of PGD testing is to help couples build a healthy family. PGD is done before the pregnancy is established and helps avoid difficult decisions and situations.
PGD helps couples who have an increased risk of a genetic disorder conceive a healthy pregnancy.
