PGT (preimplantation genetic testing)
A group of techniques that look at the genetic material of embryos created through IVF. These include:
PGT-A: preimplantation genetic testing for aneuploidy – also known as PGS (preimplantation genetic screening)
PGT-M: preimplantation genetic testing for monogenic conditions – also known as PGD (preimplantation genetic diagnosis)
PGT-SR: preimplantation genetic testing for structural chromosome rearrangements
PGT-P: preimplantation genetic testing for polygenic risk scores
