When to See a Genetic Counsellor

There are many reasons to see a genetic counsellor.

Planning for Pregnancy

If you are planning a pregnancy, you may want to see a genetic counsellor if:

You have a genetic condition.
There is a chance you have a genetic condition because it runs in your family.
You want to understand the likelihood of your baby having a genetic condition.

During Pregnancy

There are screening tests that are offered during pregnancy. These tests are called prenatal screening tests, or genetic screening in pregnancy tests. They can tell you whether your baby may be at increased risk of certain genetic or chromosomal conditions.

If prenatal screening tests show your baby has an increased risk, your doctor may recommend you:

See a genetic counsellor to discuss your options.
Have further tests.

Diagnostic tests that can confirm if your baby has certain genetic conditions include:

Amniocentesis
Chorionic villus sampling (CVS)

Genetic counselling can help you make an informed decision about whether to have additional testing.

A genetic counsellor can also support you and give you information if a genetic condition is diagnosed during pregnancy.

Caring for Your Child

Your doctor may recommend you see a genetic counsellor if your child has signs of a genetic disorder. This can provide you with information on testing and diagnosis, as well as support. You may also want information on the risks to potential future children.

Genetic Testing and Its Applications

Genetic testing can be done to diagnose some genetic conditions. There are several different types of genetic tests.

Testing can be done:

If you have symptoms of a genetic condition.
If you have a family history of a genetic condition.
During pregnancy, to check your baby for certain conditions (if they are at increased risk).

Genetic carrier screening tests are tests to find out your chance of passing a genetic condition on to your children.

Finding a Genetic Counsellor

Genetic counsellors are available in many hospitals and health clinics. The best way to find a genetic counsellor is to speak to your doctor. They can refer you for genetic counselling.

The Human Genetics Society of Australasia also has a “Find a Genetic Counsellor” service. It can help you find a registered counsellor in your area.

Tools and Assistance

Genetic Condition Education: Numerous online resources and educational tools are available to help individuals understand genetic conditions, their inheritance patterns, and potential treatments. Many organizations and health professionals provide brochures, videos, and other materials to educate families and individuals about genetic disorders, helping them make well-informed decisions regarding their health and family planning.

Genetic Counselling Services: Genetic counselling services provide guidance and emotional support for individuals and families considering genetic testing or living with genetic conditions. Healthcare professionals such as doctors, genetic counsellors, and clinical geneticists can help assess personal and family health history and offer advice on available testing options. These services help individuals understand the implications of genetic conditions and make informed decisions regarding their health and reproductive plans.

Genetic Testing: Genetic testing can help diagnose genetic conditions, including those that may be inherited. It can also assess whether a person is a carrier for certain genetic disorders. There are various types of genetic tests available, such as diagnostic testing, prenatal screening, and carrier screening, which can provide critical information about the health of an individual or their baby. A healthcare provider can assist in selecting the appropriate genetic test based on specific needs and circumstances.

Genetic Testing Kits: Home testing kits are available for some genetic conditions and carrier screening tests. These kits allow individuals to collect their own samples, such as saliva or cheek swabs, and send them to a laboratory for analysis. While these kits may provide preliminary information, it is important to follow up with a healthcare professional for a thorough interpretation of the results and further advice.

Support Services for Genetic Conditions: There are various support services available for individuals living with genetic conditions, including local and national support groups, online forums, and specialized counselling services. These resources offer emotional support, educational materials, and practical advice for managing genetic conditions. Connecting with others in similar situations can be an invaluable source of comfort and guidance.
