PGD Preimplantation genetic diagnosis (PGD) is a diagnostic test used in conjunction with in vitro fertilization (IVF) performed on embryos to assist detection of known genetic diseases or chromosomal abnormalities. Since it was first performed in 1989, PGD has become the most important advance in genetic testing to determine whether genetic abnormalities are possible with a given pregnancy. Couples known to have serious genetic disorders or who carry a genetic disease have successfully decreased the likelihood of having a child with these life-threatening afflictions. | ||
