How does urticaria allergen check

summary

In recent years, I always have a rash on my body. The hospital diagnosed it as "chronic urticaria". After treatment, it's better now. Let's understand how to check the allergen of urticaria.

How does urticaria allergen check

One: patch test: make the test object directly contact with the skin to observe its reaction. This method is often used to test allergens in contact dermatitis.

Second: IgE detection: detection of a specific allergen, such as trees, flowers, house dust mites, milk, chocolate, peanuts, nuts, eggs, seafood, fish, chicken, etc.

Third: prick test: a special prick needle is used to prick into the skin to make the test solution directly contact with the sensitized cells in the skin and cause reaction. This method is relatively simple, generally 15 ~ 20 minutes to know the results.

matters needing attention

Because the etiology of urticaria is complex, although some people can find allergens, but also a considerable number of patients are difficult to find the exact cause through the existing allergen detection methods.
