Carrier screening looks at your genes
It is a genetic test for you and your reproductive partner to look at what genetic conditions you may pass on to your children.
prepair carrier screening has three options
prepair 3 checks if you are a carrier for 3 inherited genetic conditions. This option is suitable for couples who only want to screen for conditions that are common in the Australian population.
- Cystic fibrosis (CF)
- Fragile X syndrome (FXS)
- Spinal muscular atrophy (SMA)
Cystic fibrosis (CF)
Primarily affects the lungs and digestive system.
Visit Cystic Fibrosis Australia for more information.
Fragile X syndrome (FXS)
Is the most common cause of inherited intellectual disability.
Visit Fragile X Association of Australia for more information.
Spinal muscular atrophy (SMA)
Affects the nerves in the spinal cord and causes muscles to get progressively weaker.
Visit SMA Australia for more information.
Did you know:
About 1 in 20 individuals is a carrier for either CF, FXS or SMA
About 1 in 240 couples have an increased chance of having a child with either CF, SMA or FXS
9 out of 10 of carriers have no known family history

What will carrier screening tell me?
Carrier screening looks at whether you and your reproductive partner are carriers for a range of genetic conditions. This information tells you about your chance of having children with an inherited genetic condition.- Most couples find out they have a low chance of having children with an inherited genetic condition.
- About 2% of couples have an increased chance of having children with an inherited genetic condition (see figure). In this case, our team will help you understand the results and the options available to you (such as testing a pregnancy, or IVF with genetic testing of embryos).
