Myriad MyRisk panel

Has anyone had the Myriad MyRisk test done? If so, has anyone previously had the BRCA1 & 2 test and tested negative? My oncologist wanted me to have the Bart test done but since the breast surgeon performed the original BRCA1 & 2 test (negative), he said it was best to get them to order. When I arrived there, they wanted to do the MyRisk test. Anybody have any experience with these tests?

Thanks.
