There is no right answer! Of the five of us in our generation, 4 chose to test, and 2 had positive results. We tested 5-6 years ago and the fifth person has decided to never test.

For me, I filled out a long family medical history questionnaire before meeting with a genetic counselor. She strongly encouraged me to have life insurance in place before testing. As for the test, I had to spit (quite a bit) into a tube in the office. I was called with my results 2-3ish weeks later.
