Preimplantation Screening

Preimplantation screening (genetic testing) of embryos prior to implantation in the womb is an established, but still fast-developing area of medical science.

Here at CRGH we offer two different forms of embryo genetic testing, which have different purposes:

PGS – Preimplantation Genetic Screening – is a test aimed at improving the outcome of IVF treatment. The test counts the number of chromosomes to help select the embryo with the best chance of giving an ongoing healthy pregnancy.

PGD – Preimplantation Genetic Diagnosis – is a test aimed at couples who are at high risk of having a baby with a known, severe, genetic condition. This test diagnoses which embryos will be affected with the condition with the aim of selecting only unaffected embryos for transfer into the womb.
