If skin allergens are tested, it will cost about 50 ~ 100 yuan. If there are few people, you can check with them. If there are many people, you need to make an appointment first. Some tests require that antihistamines be stopped for 3 to 7 days. For details, please go to the outpatient department of the hospital for consultation.
Hello, skin allergy is a common phenomenon in daily life, some are allergic to beef, mutton and seafood, some are allergic to metal ornaments or drugs, some are allergic to dust or pollen in the air, and so on.
When allergies occur, people are prone to skin diseases such as urticaria, asthma, rhinitis, eczema and dermatitis, which will not only cause skin itching, erythema, papules and wheal, but also affect the respiratory system, cardiovascular system, digestive system and nervous system in severe cases. Allergen testing methods in Tongchuntang Hospital mainly include in vivo test and in vitro test. In vivo test is to apply allergens to human body through skin test or prick, observe human body's reaction to allergens, and determine whether patients are allergic to these allergens; In vitro detection is to take the blood or other body fluids of patients for in vitro detection, and allergens do not directly act on the human body.
I. In vivo test
1, intradermal test: inject allergens into the body, observe the skin reaction after a certain period of time, and judge whether you are allergic to the allergens according to the skin reaction.
2. Puncture test: Puncture test can be regarded as a special intradermal test. The method is to first drop the puncture skin test liquid on the skin, and then use the puncture needle to penetrate the liquid drop and pierce the skin. Skin spot
The puncture fluid is only one tenth of the intradermal test, which is safe. Because the skin lesions are small, the patient has no pain. Generally, the international standardized antigen-Germany Arog prick liquid is used. (1) inhalation allergen
Including mites, molds, mugwort, elm willow, animal fur, pollen and so on. (2) Food allergens include fish, shrimp, crabs, pigs, beef and mutton, milk, eggs, beans, peanuts, condiments, etc. Both are 15.
The result came out in minutes.
3. Patch test: Patch test is mainly used to detect contact allergens. The specific method is to stick the reagent on the skin and observe it for a period of time, and then judge whether it is correct according to the skin's reaction to the contact substance.
This substance is allergic.
4. Cosmetic allergy detection: We can accurately detect allergens and allergic cosmetics by methods such as closed patch method, light spot method, blister liquid detection method and incision experiment method to guide patients to choose.
Suitable cosmetics.
Second, in vitro test
1.IgE antibody detection: it is a specific IgE antibody for detecting food allergic to type I and inhaled allergens. At present, the German MEDIWISS "sensitive screen" quantitative allergen detection system is commonly used.
Line confirmed. It applies protein blot technology to the routine diagnosis in the laboratory, and uses special allergen combinations for different diseases.
2.IgG antibody detection (food intolerance detection): Many chronic diseases in clinic are related to food. After removing the problematic food, the symptoms will disappear, which is food intolerance.
Accept. Food intolerance test is also the only delayed reaction (IgG) detection method for food allergy. Diarrhea, oral ulcer, urticaria, acne, migraine, fatigue, depression, asthma, sleep.
Chronic symptoms such as insomnia and grinding teeth should be examined for food intolerance, which may be related to food intolerance.
How much depends on what method you use and what hospital you test. These are not fixed factors!
