Not doing NIPT

So, my husband and I decided that we are not going to do the trisomy blood test when my doctor orders it at 16 weeks. Partially because of cost but also because of the high likelihood of a false positive. We figure, nothing will change if baby does have a high likelihood and we will be having the anatomy scan 4 weeks later anyways (which will be significantly more accurate and covered fully by insurance). Is anyone else not doing the genetic testing? Am I crazy?
