Hi Ray - Barb in Iowa here. I did the 23andMe a couple of years ago because I was curious about the results of that same test that my married granddaughter took a couple of months prior (wondered if a particular one of her results would also show up on mine, and it did, answering a long-held question that I had no relatives in my generation to ask). The test doesn't really ascertain diseases or conditions as far as probable diagnoses but will state possible susceptibilities that may exist based on what some chromosomes present. They are very good about updating you as to new potential relatives, since they are constantly receiving new test inquiries. Names may or may not be supplied - sometimes just initials, depending upon what that person gave permission to share. Everything is kept very confidential - you alone determine what you wish to make known within the database. They also update you as to medical trends that may pertain to your DNA as they receive results from others who share same. And every so often they e-mail you asking you to complete a questionnaire regarding similar questions you answered when you originally took the test. Of course you are free to ignore the questionnaires. My granddaughter has completed none, as she has no spare time, but I have probably completed about 75% of them because I know the answers help in their research, and I do have the time! By the way, my college age grandson, brother to said granddaughter, took the test a few months ago and his results confirmed ours. I have enjoyed this process.
