Allergic diseases have a high incidence in the population and are a common clinical condition. Allergen detection is important for the diagnosis, treatment and prognosis of allergic diseases. Detection of allergens and taking effective measures to avoid contact with them are the basic principles of allergic disease prevention and treatment. The Allergen Screening System uses an immunoblotting method to quantitatively detect specific IgE antibodies (sIgE) in human serum. One specimen can simultaneously determine more than 20 kinds of sIgE, including the detection and quantification of total IgE; using immunoblot technology, high reliability, good specificity and high sensitivity; incorporating biotin a streptavidin amplification technology, this amplification system in immunosensitization technology, greatly improving the sensitivity and specificity of the reaction, allowing for very small amounts of antigen detection, sensitive and rapid, highly accurate and reliable results. Technologically advanced. Why do we need allergen testing? Allergen-specific IgE is present in the blood of patients suffering from various allergic diseases such as cushings, atopic eczema and exogenous asthma, and the detection of allergen-specific IgE is of great value in diagnosing the material basis of allergic reactions and in selecting appropriate immunotherapy. Allergy is the most common type of allergic reaction and is very widespread, with bronchial asthma alone affecting nearly 30 million people in China, and other patients such as hay fever, urticaria and allergic rhinitis are also extremely common. Common allergens: ① Ingested allergens: fish, shrimp, crab, milk, cashew nuts, bread and certain drugs, etc., can cause hives, abdominal pain, diarrhea, vomiting and other symptoms, individual severe anaphylaxis; ② Inhalation allergens: mites, mold, feathers, dander, pollen, etc., most commonly cause bronchial asthma, allergic rhinitis, cushings, etc.; ③ Injected allergens: insect bite venom and certain drugs, the most common drug is penicillin; ④ contact allergens: wool, dyes, cosmetics, latex products and nickel products, etc. So which departments need testing for diseases? ENT: allergic rhinitis (incidence 10-20%), allergic laryngeal edema, etc.; dermatology: urticaria (15-20% of people have suffered from urticaria), allergic contact dermatitis, atopic dermatitis, etc.; stomatology: recurrent oral ulcers (about 85% of people before the age of 30); pediatrics: bronchial asthma, Pediatrics: bronchial asthma, allergic infant eczema, pediatric enuresis, pediatric celiac disease, etc. (nearly 30 million people have asthma in China, and it is increasing year by year; the incidence of allergic infant eczema accounts for 10-15% of all celiac disease; food allergy is the most common and most neglected); respiratory medicine: hay fever, bronchial asthma, fungal allergic dermatitis, etc.; gastroenterology: dyspepsia, belching, gastritis, gastric ulcer, celiac disease, etc. Gastric ulcer, celiac disease, ulcerative colitis, diarrhea, abdominal colic, chronic pharyngitis, itchy throat, etc. When these diseases are not cured for a long time, they are probably caused by allergies; Neurology: grand mal seizures, allergic headache, Meniere’s disease, etc. 15% of grand mal seizures are caused by allergies. There are many allergic diseases, we should go to the regular hospital in time, early detection, early diagnosis, early treatment, early return everyone a relaxed, a healthy.
