Preimplantation Genetic Diagnosis (PGD)

Preimplantation Genetic Diagnosis (PGD)

Preimplantation genetic testing is a technique used to identify genetic defects in embryos during in vitro fertilization (IVF). This genetic assay is used to evaluate embryos before transfer to the uterus. Pre-implantation genetic diagnosis (PGD) is a laboratory procedure. It is used to avoid passing the heredity problems in new progeny and also avoids pregnancy termination as it allows the selection of an embryo free of the genetic disease.
