How to detect skin allergens? It turns out there are two methods

Skin allergies are common conditions in daily life and are very harmful to human health. Therefore, if you want to avoid suffering from allergies in the future, you need to detect allergens. So how do you detect butt allergens? In fact, there are two methods, one is in vivo testing and the other is in vitro testing.

1. In vivo testing

In vivo testing is to apply allergens to the human body through skin tests or pricking methods, observe the body's reaction to the allergens, and determine whether the patient is allergic to these allergens; in vitro testing is to take the patient's blood or other body fluids for in vitro testing, and the allergens are not directly applied to the human body.

1. Intradermal test: Allergens are injected intradermally, and the skin reaction is observed after a certain period of time. The allergy to this allergen is determined based on the skin reaction.

2. Prick test: It can be regarded as a special intradermal test. The method is to first drop the prick test solution on the skin, and then use the puncture needle to pierce the droplet and into the skin. The amount of liquid pricked on the skin is only one ten-thousandth of that in the intradermal test and is much safer.

3. Patch test: mainly used for the examination of contact dermatitis. The specific method is to stick the reagent on the skin and observe for a period of time, and then judge whether you are allergic to the substance based on the skin's reaction to the contact object.

4. Cosmetic allergy testing: Accurately detect allergens and allergic cosmetics through closed patch method, light patch method, blister fluid test method, scratch test method, etc., and guide patients to choose appropriate cosmetics.

2. In vitro test

1. MinScreen Quantitative Allergen Detection System: MinScreen Quantitative Allergen Detection System is a technologically advanced and creative allergen quantitative detection system. It applies the immunoblotting technology used for scientific research to daily laboratory diagnosis and uses special combinations of allergens for different diseases. It can be used to screen antibodies for many diseases. The system method is reliable, with a specificity similar to that of skin tests and consistent with the results of conventional in vitro single allergen detection tests. It mainly detects IgE for type I allergic reactions, and allergens can be easily detected with just one drop of serum. Its characteristic is high accuracy.

2. Food intolerance test: Clinically proven, many chronic diseases are related to food. After removing the problematic food, the symptoms will disappear. This is food intolerance. The food intolerance test is also the only delayed reaction (IgG) test for food allergies. Chronic symptoms such as diarrhea, oral ulcers, urticaria, acne, migraine, fatigue, depression, asthma, sleep disorders, bruxism, etc. should be tested for food intolerance if the cause cannot be found, as they may be related to food intolerance.
