Genetic testing

Pre-implantation Genetic Testing (PGT) of embryos is designed to uncover specific genes that could result in a disease or chromosomal abnormalities that could prevent a successful pregnancy

What type of pre-implantation genetic testing does Bourn Hall offer?

Bourn Hall provides pre-implantation genetic testing for:

  • Monogenic diseases (PGTM)
  • Structural chromosomal rearrangements (PGT-SR)
  • Aneuploidy screening (PGT-A)
All of these genetic tests involve the removal of a cluster of cells from the embryo for screening.


PGTM is recommended where there is a known genetic condition within families or if a couple have previously had an affected child.


PGT-A involves screening embryos for basic chromosome abnormalities such as Down Syndrome. PGT-A can also be used to identify the gender of an embryo prior to implantation.


PGT-SR is recommended when one of the parents is a carrier of structural chromosomal rearrangements. These are changes from the normal size or arrangement of chromosomes. Chromosomes are the structures which hold genetic material.
