What is PGD?

Preimplantation Genetic Diagnosis (PGD), also known as Preimplantation Genetic Screening (PGS), is a reproductive technology procedure performed by IVF specialists at atlasCARE IVF on embryos prior to implantation and pregnancy to detect chromosomal/genetic normalcy.

The procedure is based upon the removal of cell(s) from an embryo on day 3 or 5 after fertilization. PGD requires in vitro fertilization (IVF) to obtain oocytes or embryos for evaluation.

What is PGS?

Preimplantation genetic screening (PGS) is a powerful genetic test that may be performed on embryos during IVF treatment to screen for numerical chromosomal abnormalities. The test offers comprehensive analysis of all 24 chromosome types: the two sex chromosomes (X and Y) and the 22 other non-sex chromosomes.

Which PGD methods does atlasCARE offer?

There are 2 types of PGD — routine PGD and array CGH 24 sure.

routine PGD is a genetic testing procedure – test chromosomes 13, 18 and 21, which are the causes of almost 90% of all genetic-linked abnormalities such as down’s syndrome.

array CGH 24 sure is also a genetic testing done on day 5 by freezing the embryos as it is more detailed testing. It tests all chromosomes. This is generally done in unexplained miscarriages or deaths or if there is a problem in family history.
