I realize I'm a year behind in answering, but I just joined and found this post. I just had the Genetic Test through Prometheus labs... received my results yesterday. It was super easy and really fast. It was $329. My results came back negative. However, I'm having good results from eating gluten-free so I plan to continue since my father and my grandmother both have Celiac. I'm completing my first month of gluten-free. www.MyCeliacID.com is the website to learn more or order your test.
