Genetic and genomic testing
Genetic testing – sometimes called genomic testing – finds changes in genes that can cause health problems. It's mainly used to diagnose rare and inherited health conditions and some cancers.
Why would I be offered a genetic test?
You may be offered a genetic test because:
- your doctor thinks you might have a health condition caused by a change to 1 or more of your genes
- someone in your family has a health condition that's caused by changes to genes
- some of your close relatives have had a particular type of cancer that could be inherited
- you or your partner have a health condition that could be passed on to your children
If you have any questions, talk to your doctor about having a genetic test.
What a genetic test can tell me
A genetic test can:
- help to diagnose a rare health condition in a child
- help you understand whether an inherited health condition may affect you, your child or another family member, and help you decide whether to have children
- show if you are at higher risk of getting certain health conditions, including some types of cancer
- guide doctors in deciding what medicine or treatment to give you
- guide doctors on whether you're able to join a clinical trial
