Test for an Allergy to Iodine - Follow whatever procedure is required by your health insurance provider for referral to an allergen specialist.
Contact the allergist and ask what process he uses to test for shellfish allergies.
Testing for an allergy to shellfish can take one of three forms: scratch, intradermal, or patch. It's best to know which test your selected allergist uses so you can be prepared. A scratch test is administered by applying a small amount of concentrated allergen to the skin and then scratching or pricking the application site for skin cell exposure. The intradermal test requires injection of the allergen concentrate into the upper layer of the skin and the patch test requires surface skin application of the allergen in patch form for prolonged exposure, sometimes lasting up to two or three days.
Inform your allergist of any prescription or over the counter antihistamines you are taking. He or she may want you to stop taking any such medication to keep it from skewing the results of your test. Verify how long you should be off of any such medication before your test so you can schedule your test accordingly.
Verify whether your allergist will administer an antihistamine after the scratch or intradermal test. If not, ask if you can take a medication when you get home should the test leave you feeling uncomfortable.
The most common allergic reaction associated with iodine is actually caused by muscle protein in shellfish. An allergic reaction to shellfish can be serious, but a fairly simple test administered by a medical professional can diagnose this allergy and help you avoid exposure. Here's what to do if you feel you need to be tested for an allergy to shellfish.
