Testing for haemophilia before pregnancy

Te whakamātau i te mate toto tepe-kore

If you know you're a carrier of a gene for severe haemophilia and want to avoid passing haemophilia to your sons, you can ask for pre-implantation genetic diagnosis (PGD).

If you have a family history of haemophilia but do not know if you're a carrier, you can ask for carrier testing.

What PGD involves

It's essential that you have counselling to know precisely what will happen and agree to it (this is called informed consent). You'll also need some blood tests before PGD.

When the blood tests are completed, you and your partner will go through in vitro fertilisation (IVF) to produce embryos. Each embryo will then be carefully tested to see if it has the haemophilia gene. You and your partner will decide with the fertility specialist which embryos to implant so you can become pregnant.

Access to PGD in Christchurch

PGD for severe haemophilia is available in Christchurch through the co-operation of Canterbury Health Laboratories, Fertility Associates and Te Whatu Ora – Health New Zealand Waitaha Canterbury Haemostasis Service.

You do not have to live in Canterbury to get PGD in Christchurch. Funding for New Zealand residents is available from the Ministry of Health nationally. Anyone can ask for PGD in Christchurch, no matter where they live.
