Genetic testing can be used to assess your chance of developing or passing on a genetic condition, or confirm/rule out a suspected genetic condition. Testing is only possible in some families and must start with a relative who might be affected. It is not always possible to detect a gene fault in the family.
If a gene fault is found, testing can be offered to other family members to help assess their risk of developing the condition.
Genetic counselling is required before and after testing and is an opportunity for you to discuss any questions or concerns you may have.
Genetic testing involves a blood test to analyse your DNA. No other invasive procedures are required.
