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.

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

PGT-A – Preimplantation genetic testing for aneuploidy (chromosomal abnormality) (PGT-A), also known as preimplantation genetic screening (PGS), is a very early method of screening the chromosomal make-up of embryos with the aim of reducing the risk of miscarriage, multiple pregnancy and time to pregnancy for specific groups of patients.  Please refer to for further information on PGT-A. 

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. Please refer to for further information on PGD.
