Trialnet results

I was just wondering about the test that Trialnet offers. Did most of you with a child that has a sibling, parent, or close family member with Type1 choose to have the test done? How long does it generally take to get the results and should I expect them by mail, email, or will they call me? I sent my daughters off 2 weeks ago and of course 14 days has felt like an eternity.
