What are the roles of allergen testing in children?

Children may suffer from various diseases as they grow up, so they are given various vaccines to prevent them. In addition, respiratory diseases are also common diseases in children, especially allergic respiratory infections, which require early allergen testing. In order to ensure the health of children, we must take as many precautions as possible to prevent problems before they occur. This is also the role of children's allergen testing.

The role of children's allergen testing is mainly reflected in the fact that many skin diseases in clinical practice are related to allergens. Many children's allergic reactions worsen repeatedly because the allergens are not discovered in time. So don’t think that allergies are just a minor problem and ignore testing.

Enzyme immunoassay is used to detect allergens quickly, accurately and painlessly. This method can be used for qualitative and quantitative detection of allergens (total IgE, total IgG, specific IgE, etc.) in patient serum or plasma. IVT is used to detect IgE-mediated immediate allergic reactions. Immediate allergic reactions have obvious seasonality, short onset time and high incidence. This test solves the difficulty that conventional skin tests are not suitable for detecting allergens during the attack period of patients with type I allergic reactions. FIgG is used to detect delayed allergic reactions. The reaction is mainly food related, that is, food intolerance. Symptoms may appear several days or a week after exposure to the allergen. These allergic reactions are often misdiagnosed due to delayed onset of symptoms, and clinically manifest as chronic symptoms in various systems. If the cause of the disease is unknown, recurring, and difficult to cure, it is recommended to check food IgG.

Allergen screening tests are suitable for the following groups of people: patients with unknown allergies, eczema, urticaria, allergic rhinitis, asthma, psoriasis, etc. should undergo allergen testing, which will be of great help in preventing and treating diseases.

The test kits currently used in hospitals for allergen testing can be roughly divided into the following types: 1. Screening test for inhaled allergens; 2. Screening test for ingested allergens; 3. Classification test for inhaled allergens (this test kit can detect the specific inhaled substances that cause allergic reactions, such as dust mites, pollen, etc.); 4. Classification test for ingested allergens (it can also detect the specific foods that cause allergies).

In fact, the role of children's allergen testing is to promptly detect possible allergies in children, and then promptly detect allergens and take effective measures to avoid or treat them. It is very necessary in the healthy growth of children, especially some allergies that may occur in the respiratory tract, which cannot be ignored. For the better growth of children, it is recommended that parents have their children tested for allergens.
