Preimplantation Genetic Screening (PGS)
Preimplantation Genetic Screening (PGS) is the genetic test used to screen the health status of embryos before they are transferred to the uterus in an IVF cycle. Many embryos look normal but have the wrong number of chromosomes (called aneuploidy) and cannot give rise to a normal pregnancy. PGS offers a better embryo selection for transfer, hence increasing the chance of having normal live baby.
