Genetic Testing

Preimplantation Genetic Testing (PGT) is a sophisticated scientific technique which can be used to test embryos for either a specific known single-gene condition or chromosome variation. Chromosome variation is a common cause of miscarriages which can turn your fertility journey into a painful and emotional experience. Genetic testing enables chromosomally healthy embryo or those unaffected by a specific disorder to be selected for transfer during an IVF cycle, increasing the change of a healthy baby.

Testing is an option if your specialist has reasons to believe that there is a specific risk, or if you want to optimise your chances of a healthy pregnancy.

What is PGT (PGT-A, PGT-M, PGT-SR)?

When the embryo in the lab is 5 days old, we extract a number of cells through an embryo biopsy. Your embryo keeps growing in the incubator, and as it develops we test a very small number of cells through preimplantation genetic testing or PGT.

Risks of PGT

Cost of PGT

The cost of preimplantation genetic screening depends on the applicable rates at your chosen fertility clinic. In general, a preliminary assessment will incur a standard fee, and tests are then charged per embryo or applying a capped fee to test a number of embryos from one IVF cycle. It is important to know that the costs of PGT are in addition to your IVF costs and that embryo screening does not attract Medicare rebates (Australia). Limited public funding may be available if your fertility clinic is in New Zealand (PGT-M) .

Choosing a fertility clinic who does PGT

If your fertility clinic has in-house PGT services, then the process will be more integrated and may give you earlier access to the outcomes of your test.
If your clinic makes use of a third-party provider, the test cells make use of secure specialised transport to the test lab.
If your fertility clinic does not deliver the PGT service internally, make sure to enquire about the exact protocols and timeframes, to ensure that you are well-informed about expected delays.

State policies/NZ legislation

Please note that in Australia and New Zealand, specific policies apply around the legality of available tests. In particular, when testing creates a situation where couples could apply sex selection when selecting an embryo, states have particular legislation in place.

In New Zealand, preimplantation genetic diagnosis is subject to different ethical views, and there are guidelines for fertility specialists.

Ask your fertility specialist which legislation applies to your local area before making decisions about your preimplantation genetic testing.
