What Are the Items to Be Checked for Allergy Testing?

Update Date: 2024-05-16 Source: Network

Allergy is a common skin condition that mainly occurs in individuals with sensitive constitutions. It is primarily caused by contact between the skin and allergens. Therefore, individuals with sensitive skin should be aware of their skin allergens. Allergens can be detected through inhalation allergy screening tests, serum total IgE tests, and other related examinations. It is essential to avoid contact with allergens in daily life. When allergies occur, it is important not to scratch the skin with hands and to promptly seek medical treatment with appropriate medications.

1. Inhalation Allergen Screening Test (Phadiatop):

This is the first step in the detection of specific allergic reactions. The Phadiatop screening reagent contains common allergens in the air, such as dust, pollen, fungi, mites, and dander. If a patient is allergic to these substances, their serum will contain SigE, and the Phadiatop test result will be positive. A positive result indicates that the patient's symptoms are caused by an allergic reaction, and further specific allergen testing is needed to identify the causative allergen. A negative result suggests that the patient's symptoms are not caused by common allergens.

2. Food Allergen Screening Test (fx5E):

This test screens for allergies to soybeans, peanuts, milk, eggs, wheat, and fish. If a patient is allergic to any of these foods, their serum will contain SigE, and the fx5E test result will be positive. A positive result indicates that the patient's symptoms are caused by an allergic reaction. Specific testing should be conducted on the foods mentioned above to identify the causative allergen or to avoid ingesting these foods and foods containing these ingredients. A negative result suggests that the patient's symptoms are not caused by the allergens tested, and they can consume these foods without concern.

3. Serum Total IgE (TigE) Test:

This test quantitatively measures the total IgE level in human serum or plasma. Elevated levels of circulating total IgE antibodies are often associated with allergic reactions. If the measured value is less than 60ku/L, it suggests that the patient's symptoms may not be caused by an allergic reaction, and allergic diseases can be excluded by combining the results of fx5E and Phadiatop tests. If the measured value is greater than 60ku/L, there is a high suspicion of allergic diseases.
