Abby this sorta reminds me of my family DNA test. When I applied our Admin asked me who my immigrant was. It was a choice of 2 men and had been an on going debate for over 25 years. I told her I didn't care I just wanted the truth. Well when my results returned it turned our family history upside down. But heck I just wanted the truth and finally got it.

Annie what is the simple blood test for CMS? Does it go to Mayo?
Thanks
Mike
