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,
