Genetic Testing is done at one lab in this country. It's Myriad Lab in Utah. It's a regular monopoly. They don't accept assignment because, well, they don't have to. They just take blood and then test for the BRACA gene. You can get one of three outcomes. BRACA-positive, BRACA-negative, or Gene of Unknown Orgin, or something to that effect. The third one is when they don't recognize the genetic material. If later on, someone genetic material matches your unknown, they say they will let you know about it. The testing is extremely expensive, upwards around $6- or $12,000 I don't remember which. I had to pay about two thousand on my own.
Having the BRACA Gene means it is very very likely that you will contract ovarian cancer. It is useful in making surgical decisions. I really didn't need it because I was going to do a hyster anyway, but I wanted the info. Someday, when I have some money, I'm going to look into what tests I can get done because I am adopted and some genetic information would be good for my son to know. Was there more you wanted to know?
