How to do an allergy test

Allergy is an overreaction of the body's immune system to certain substances (allergens), which may cause symptoms such as skin itching, redness and swelling, and difficulty breathing. It is important to know the allergens and take appropriate measures. Below is a detailed guide to allergy testing, including common methods, suitable groups, and precautions.

1. Common methods of allergy testing

Allergy testing is done primarily through skin testing, blood testing, and elimination methods. Here is a comparison of the three methods:

2. Applicable groups for allergy testing

Allergy testing is recommended if:

1. Recurrent rash, rhinitis or asthma symptoms;

2. Family history of allergies;

3. Abnormal reactions such as vomiting and diarrhea occur after food intake;

4. Allergy symptoms occur after using the drug.

3. Things to note before testing

1.Discontinuation requirements: Antihistamines (such as loratadine) need to be stopped for at least 3 days before the test;

2.avoid irritation: The skin at the test site should be free of damage and eczema;

3.diet: Blood test does not require fasting, but avoid high-fat diet.

4. Interpretation of results after testing

5. Precautions for special groups of people

1.infants: It is recommended to give priority to blood testing. Skin testing may affect the results due to crying;

2.pregnant woman: Avoid skin testing and choose serum IgE testing;

3.People with a history of severe allergies: Testing needs to be carried out in a medical institution with complete emergency equipment.

6. Allergen avoidance and daily management

Based on the test results, the following measures need to be taken:

1.environmental control: Those who are allergic to dust mites should use anti-mite bedding to avoid going out during the pollen season;

2.diet modification: Avoid allergenic foods and pay attention to cross-reactions (for example, those allergic to birch pollen should eat apples with caution);

3.emergency preparedness: Carry an epinephrine pen (such as EpiPen) with you.

7. Latest allergy research trends (hot spots in the past 10 days)

1.microneedle array technology: An American research team developed a painless microneedle allergy test with a 20% accuracy increase;

2.Artificial Intelligence Prediction: British scholars use AI to analyze patient history and can predict 89% of allergy risks;

3.New desensitization therapy: Sublingual immunotherapy for peanut allergy enters Phase III clinical trial.

Through scientific allergy testing and personalized management, allergic symptoms can be effectively controlled and quality of life improved. It is recommended to formulate a prevention and treatment plan under the guidance of a professional doctor.
