<<Disclaimer: Verify this information before applying it to your situation.>> I am having a cat scan done and was given a jug of barium sulfate suspension to drink before the test. I asked what the ingredients were and the technician had no idea and nothing available in the department. However there was an 800 number on the bottle and I called. Got a knowledgeable person who knew what celiac disease is and said, "Do not take this." He recommended another barium mixture. The name of the barium mixture with wheat in it is: Readi-Cat #729. The different barium sol. was not available at my hospital, so I have to take a different contrast medium. It is all arranged, but I am still in shock that the hospital is so ignorant of this disease. We even have a celiac support group that meets at the hospital once a month! Janet Easton
