Should I avoid foods with a positive IgE test?

Question

Hello doctor,

I have some questions regarding allergies.

When I was a kid, I had eczema on my mid-arms, which went away later. Some years ago, when I was around 22, it came back aggressively on my face, neck, and shoulders. Then, I was referred to blood food allergy tests (IgE). A lot of allergens were detected (wheat, melons, peach, cucumber, potato, parsley, carrot, etc). I did avoid those foods.

After seven years, I wanted to test it again, and unfortunately, the test showed the same results, more allergies (coconut, plum, chestnut, and buckwheat - things I eat regularly). I also did the Faber test and had a lot of red lines. The doctor told me that none of those tests is 100 percent sure, and I should test all foods. But I am very afraid of the anaphylaxis reaction.

I am now afraid to eat coconut, chestnut, etc., which I did regularly eat before, not to have a severe reaction (not have one earlier though). I wanted to ask if the most severe reaction can develop with any food. Even for meals that I regularly eat and have no problems with.

Please help me.

Thank you.

Hello,

Welcome to icliniq.com.

Yes, some foods can cause urticaria, and rarely angioedema, like peanut and seafood allergies. However, the test you mentioned is not significant, as it is a very nonspecific kind of test. Most of the people who get tested find themselves allergic to hundreds of things like that. Hence, it is not significant. And you have been eating them all regularly before, so I do not see any reason to stop them now.

I hope this clarifies your doubts.

Please let me know if you need any help.

Thank you.
