Who Is a Candidate for PGD?
Candidates for pre-implantation genetic diagnosis (PGD) are couples who have already had, or have been determined to be at high risk for having, a child with a known genetic disorder. It is important to realize that this procedure is not for the purpose of broad genetic screening. In order to detect problems, the embryologist must know what to look for. Conditions that are commonly tested for include Down syndrome, cystic fibrosis, Tay-Sachs, Thalassemia and sickle cell disease.
