Process of Genetic Counselling and Testing

How is genetic testing done?

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. 

What is the process of genetic counselling and testing?

1. 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
2. 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
3. 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.
4. 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
