How many items of allergens should be checked

Although checking allergens is a very complicated process, many people often suffer from allergies in their daily lives, which causes great torture to a person's body and mind. Therefore, some people want to find out their allergens to prevent allergies from occurring in the future. Before checking for allergens, everyone should also understand the projects and detection methods for allergens.

What are the common allergen detection items?

Inhalant allergen screening test (Phadiatop) test: It is the first step in detecting atopic allergic reactions. The phadiatop screening reagent contains common allergens in the air such as dust, pollen, fungi, mites, dandruff, etc. If the patient is allergic to them and the serum contains SigE, the phadiatop test result will be positive. If the test result is positive, it indicates that the patient's symptoms are caused by an allergic reaction, and specific allergen testing is required to determine the causative allergen; if the test result is negative, it indicates that the patient's symptoms are not caused by common allergens.

Food allergen screening test (fx5E) is a screening test for soybeans, peanuts, milk, eggs, wheat and fish. If the patient is allergic to any of these, and the serum contains SigE, the fx5E test result will be positive. A positive test result indicates that the patient's symptoms are due to an allergic reaction. The above foods should be specifically tested to determine the allergens that cause the disease, or the above foods and foods containing the above food ingredients should be avoided. If the test result is negative, it means that the patient's symptoms are not caused by the above allergens and the above foods can be eaten safely.

Serum total IgE (TigE) test: It is a quantitative determination of total IgE levels in human serum or plasma. High levels of circulating total IgE antibodies are often associated with allergic reactions. If the measured value is less than 60ku/L, it indicates that the patient's symptoms may not be caused by an allergic reaction. Combined testing of fx5E and Phadiatop can rule out allergic diseases. If the measured value is greater than 60ku/L, allergic diseases should be highly suspected.

Specific IgE (SigE) test: It is a test for a specific allergen, such as milk, eggs, fish, house dust mites, chicken, duck feathers, dog hair, pears, peaches, etc. It is generally divided into 7 levels from 0 to 6, with 0 being no allergy, 1 being a milder allergy, and 6 being the most severe.
