If i am allergic to iodine would i be allergic to thallium?

Iodine and thallium are different elements, and an allergy to one does not necessarily imply an allergy to the other. Allergies are typically specific to certain proteins or compounds, and thallium is a heavy metal with different chemical properties. However, if you have a known allergy to iodine or iodine-containing compounds, it's important to consult with a healthcare professional for personalized advice and potential cross-reactivity concerns.
