i LOVE that you diagnosed my MTHFR. i dont love that you tke so much blood - as an ameic - thats had! i dont love that my orthopedist told me your full body MRI was worthless and a weaste of money - which I agree because you diagnosed a torn labrum on my right which is actually on my left - an you didnt put right ot left for anything else for my hips or knees. i also dont likje that in allllll the prep emails and warnings before you pay AND in the actual MRI, NO ONE told me to hold my breath so I wasnt tested properly. Not once was that mentionerd. I mean you gave me a refund which I appreciate but I wanted the test. Also Manhattan is very far - why cant you do the full body on Long Island?
