What is PGD?

PGD is known as a preimplantation genetic diagnosis which provides you with information related to gene makeup cells that can be found in Embryo. An embryo is a fertilized egg. An embryo biopsy evacuates almost 8 cells every single day and sends them to the clinical lab for testing. This is the process generally designed to examine inherited gene disorders. Post the PGD testing, your surgeon may freeze the embryo for further use.

Who is suitable for a PGD?

A PGD is taken by couples who have a family history of any serious health condition. They take this test because they wish to clear out their doubts about whether they have any type of genetic problem or not. PGD can be helpful to find out about conditions such as single-gene disorders which include cystic fibrosis and sickle cell anaemia. This test takes by couples if their ancestors have any type of sexual problems such as Fragile X syndrome and Duchenne muscular dystrophy.

What is PGS?

PGS stands for preimplantation genetic screening which is designed to check the normal range of chromosomes that are present in embryo cells. This test is performed after the growth of embryos to count the number of chromosomes that are present in each cell. In scientific terms, embryos with the normal range of chromosomes are additionally known as Euploid. Whereas, embryos that do not have the desired number of chromosomes, which is 46, are known as Aneuploid.

Who should get PGS?

This test is taken by those couples who are above a certain age as an abnormal number of chromosomes is commonly experienced by old-age women. Abnormal embryos could lead to many fertility defects such as miscarriage, biochemical pregnancy, fetal death later in pregnancy, and having a baby with abnormalities.
