<<Disclaimer: Verify this information before applying it to your situation.>> Just had an upper GI series and had to swallow a barium solution. I felt crummy afterwards and checked back with the radiology lab and they said it was GF. There answer was "inadequate" to my way of thinking. Anybody know about the GF status of the barium solution used in xray work? It is flavored and slightly sweet, so it isn't only barium. Couldn't find anything on a search here. TIA, Leif
