dye

 [di]
any of various colored substances containing auxochromes and thus capable of coloring substances to which they are applied; used for staining and coloring, as test reagents, and as therapeutic agents.

dye

(),
A stain or coloring matter; a compound consisting of chromophore and auxochrome groups attached to one or more benzene rings, its color being due to the chromophore and its dyeing affinities to the auxochrome. Dyes are used for intravital coloration of cells, staining tissues and microorganisms, as antiseptics and germicides, and some as stimulants of epithelial growth. For individual dyes, see the specific names. Commonly but improperly used for radiographic contrast medium.

Patient discussion about dye

Q. Has anyone had an allergic reaction to gadolinium dye, MRI contrast agents, I have had a severe reaction. I would like to know the long term effects of this dye. And if anyone else has had or heard of problems and reactions to it. Please answer me. Thank you

A. In 1969 I almost died from the IVP dye. I had no idea I was allergic and when I awoke I was in a "recovery room." The doctor told me to always tell any physicians/paramedics etc of my allergy status regarding the dye. I now have chronic back pain, have a history of cancer in the family and the doctor wants to do a scan (including dye) but when I emphasized that I was allergic he backed off. Now I am wondering if there is anything else that can be done to test the bone (scan) without the dye. Any answers? Thanks
