Process of Genetic Counselling and Testing

Genetic testing typically is a one-time blood test. If a blood sample cannot be taken, other sample sources (e.g. skin or saliva) may be explored.

Pre-test genetic counselling

Before genetic testing is conducted, a consultation (~30 mins- 1 hour) will be arranged with a genetic counsellor and/or medical oncologist to discuss the following:

- Personal and family history of cancer and/or disease
- Assessment of how likely a hereditary cause is the reason for the cancer(s) in the family and whether genetic testing is recommended
- Benefits and limitations of genetic testing personalized for you and your family
- Implications of the genetic test result on insurance, legal and privacy issues
Obtaining consent for genetic testing
Genetic testing is a personal choice, and no one is forced to go ahead with it. You need to consent to genetic testing before it is conducted
Collection of samples
A blood (sometimes skin or saliva) sample will be taken for genetic testing. Most genetic test results are ready in 2 – 6 weeks. As such, the clinic will schedule an appointment to discuss your test result with you after that period.
Result appointment
Your result appointment will involve a discussion of the following aspects of your genetic test result:

- What this result means for you and your family
- Whether anyone else in the family should also consider genetic testing
- Personalised recommendations on how to manage and reduce your cancer risks based on your result and your family history of cancer (if any)
- Referrals to other specialities (if needed) to facilitate the cancer risk management plan recommended to you

There are 3 types of results that you may receive from genetic testing:
