Genetic Testing Insurance Coverage

I am 11 weeks today and going back to the doctor tomorrow for more information on genetic testing. Last time I was there, he mentioned the Harmony test because it is more accurate than other testing. Harmony is a Labcorp test but has now been replaced with InformaSeq as of 1/2015. I have Horizon BCBS insurance and was wondering if it was covered? I can't pay out of pocket. What are your experiences with this test? I am not high risk, he just recommended it.
