Yes, that's very much a part of what we do. When we're discussing a predictive test with a patient—I'll use Huntington’s disease as an example—we discuss not only the implications for that person of a positive or negative test result, but depending on the family structure and how they are connected to an affected member of their family, we discuss what their test result will and won't tell them about other family members.
We discuss if and how they would disclose their test result to other family members. All of that is called “genetic counselling”. It's very much a part of the contract that I have with my patients. As Dr. Forbes said, if a patient tells me that they want their test result to be kept confidential, then I must respect that.
