Preimplantation Genetic Diagnosis 

PDG is used to screen embryos at risk of developing serious single gene (monogenetic) disorders, such as cystic fibrosis, Huntington disease, and spinal muscular dystrophies. PGD allows specialists to determine which embryos are affected with a single gene disorder prior to implantation, and is therefore most beneficial to high risk couples with a family history of severe monogenetic disorders. This ensures that all embryos to be implanted are absent of any genetic disorders.


PGD is an exceedingly complex procedure. Here at Compass we want to guide you and ensure you choose a treatment plan that is appropriate for your circumstances. If you want to learn more about PGD and how it can benefit your treatment, complete the form below and one of our scientists will be in touch, or scroll down to read more.

About PGD

PGD is a technique that can be used by couples who have concerns regarding family history or know that they carry a serious genetic condition. PGD can then be used to reduce the chances of passing on that genetic condition to a child.

PGD is a specific screen, meaning that when undergoing the test our lab needs to know which specific genes to look for. Often finding the gene is a long process and is complicated by the need for extensive testing on patients prior to the IVF cycle. This can be a stressful time, and as such, we assign a genetic counsellor to each of our patients so they understand the process and are able to make an informed decision regarding their results.

Important facts  

  • Because of the nature of PGD, Compass caps the total possible spend. This means that you will not pay more than $2,992, regardless of the number of embryos being tested.

  • You will need to speak with a genetic counsellor prior to commencing your cycle to ensure that we fully understand the genes being screened.

  • When you undergo PGD, it isn’t possible to receive a "fresh" transfer as all cells have to be analysed after the embryo reaches Day 5. This means that all embryos are frozen and transferred after analysis has been completed.

  • Please note we may have to develop a new testing protocol if we have never tested for your particular gene type before. This process may take some time, and we will discuss with you prior to your egg pick-up (EPU).
