Preimplantation Genetic Diagnosis (PGD)

PGD stands for preimplantation genetic diagnosis, which is a reproductive technology used during in vitro fertilization (IVF) to test embryos for genetic disorders before they are transferred to the uterus. PGD is typically used when one or both partners have a known genetic disorder, or when they are at risk of passing on a genetic disorder to their offspring.

The process of PGD involves the removal of one or more cells from an embryo during the early stages of development. The cells are then tested for specific genetic abnormalities using specialized laboratory techniques, such as polymerase chain reaction (PCR) or fluorescence in situ hybridization (FISH).

Embryos that test negative for the genetic disorder can then be transferred to the uterus for implantation. This can help to reduce the risk of passing on a genetic disorder to future generations.

PGD can be used to test for a wide range of genetic disorders, including cystic fibrosis, sickle cell anemia, and Huntington's disease, among others. It may also be used in cases where the parents are carriers of a genetic disorder but do not show any symptoms themselves.

It is important to discuss the benefits and limitations of PGD with our genome consultant and genetic counsellor to determine if it is the most appropriate treatment option for each individual or couple.
