My Mom's allergy to iodine

[Guest guest]

Since last summer I've become involved with my Mom's medical

appointments. She's 83 and was told many years ago that she's allergic

to iodine. I've wondered for some time how this got into her charts and

the topic came up again this week at an appointment for a ct scan. I

know she's very allergic to shellfish and bee stings.

I'm wondering if maybe she had a ct scan in the past and had a bad

reaction to the contrast. Is that how people get labeled as being

allergic to iodine? Is it radioactive iodine in that contrast people

drink prior to a ct scan?
