total sham. I haVE BEEN there few times they eithert switch the study on you or they lie to you and keep you hanging and never call you back . I have excellent lab result and once they lied about my lab result and I say keep complaINIG AND NO WONDER FEW POEPLE ALMOST DIED GOING TO THIS PLACE. i HAVE HEARD MANY COMPLAITS ABOUT THIS PLACE AND ALSO WHEN YOU GO FOR SCREEN ING THEY KEEP YOU FOR HOURS AND HOURS AND USUALLY YOU HAVE TO ALSO FAST. I have heard very awful stories and one lady told me she was so hungry and didn't eat for almost 15 hours before they see and lab result was screwed up cuz they kept her so long and off course is run by seems like very unprofessional people
