Has anyone had the cell-free DNA test (aka MaternT21) and tested for xy chromosomal abnormalities?

Linocen
I had this test primarily to find out chances of Down syndrome and trisomy 13/18 abnormalities.  My test came back positive for XXY which the genetic counselor said only means I have a higher risk of the baby having that. The only way to tell for sure is to do amnio.  
Has anyone else had an experience like this? Did u do amnio to confirm? The XXY syndrome is not life threatening but the syndrome causes infertility and lower bone density/ muscle mass. 
We're waiting for our doctor to get back from vacation to get her input but any advice is appreciated!!
