Progenity Testing

So I saw someone put a post up about genetic testing and I was wondering if the progenity test was going to test me or the baby. My ob said it was non invasive blood draw and a series of ultrasounds. She also told me it was optional but the only reason why I am considering it was because I was a heavy drinker and was drinking a lot before I even found out I was pregnant.. Can any body give any information? Have you had it done?
