Does anyone know if the Harmony test replaces the NT scan if you chose to do that route? I did the harmony test last week and am awaiting my results. I was never scheduled for the NT scan and want to know if that's bc we opted for the harmony test? Does one replace the other? I asked my dr office but they didn't really answer my question they just said what both of the test are for.  I'm 12.5 weeks- would there be any reason to call and order the NT scan? Thank you for your help!!
