Whats the dye used in angiography? ive tried researching online, but cant find an answer. im allergic to a lot of things, and im afraid i might have a bad reaction to the dye/contrast medium. how can i find out?

Hyperosmolar : Hyperosmolar radio contrast media have caused problems in the past. Low molarity dyes are currently being used with a much lower risk.. There is no reason to suspect you will have a reaction, unless you've had a previous reaction since these dyes do not cross react with things you may be allergic to.

Different dyes used: Ask your cardiologist or radiologist who is performing the procedure and ask what dye is going to be used. There are different classes of rcm and they are classified according to their tonicity. The isoosmolar reagents are the least likely to result in reactions. Let your physician know your concerns and they will walk you through the options.
