Diagnosis of Allergic Diseases and Asthma
Allergic diseases occur due to the body’s hypersensitive response to allergens, causing abnormal symptoms in various systems triggered by allergens. Generally, when allergy symptoms occur, patients often take antihistamines to reduce symptoms, which only addresses the symptoms without identifying the specific allergen. Proper allergy treatment requires patients to know which allergens they are allergic to, such as pollen, flowers, animal dander, dust mites, food, drugs, and insects, to avoid them and receive appropriate treatment. This helps improve symptom and disease control. Currently, allergy testing can be done via skin tests and blood tests to detect specific IgE antibodies against allergens.
- Skin Testing
Allergy skin testing involves pricking the skin and applying extracts from allergens such as dust mites, pollen, fungi, insects, and food to determine which allergens cause reactions. This test can be performed on both children and adults, with results available in about 20 minutes.
- Immunological Blood Testing
Allergy testing by blood sampling is used in certain cases where skin testing is not possible, such as in patients with a history of severe allergic reactions (anaphylaxis) or those with extensive rashes and insufficient normal skin for testing. It is also an option for young children who cannot undergo skin prick tests. Blood test results take about 1-2 weeks as samples are sent to a laboratory.
- Oral Food Challenge
This test is conducted by allergy specialists in the hospital. Patients are closely monitored and safely managed. The doctor gradually gives the child suspected allergenic food in appropriate types and amounts over a period, observing symptoms closely for about 4-6 hours. This confirms whether the child is allergic to the food and assesses the severity and threshold of the allergic reaction to guide management and follow-up.
Allergy Treatment
- Medication Currently, allergy medications are highly effective and available in both oral and nasal spray forms.
- Allergy Vaccination
- Sublingual immunotherapy is used specifically for patients allergic to dust mites “Dust Mite Allergy Sublingual Vaccine” for treating dust mite allergies | Phyathai Hospital (phyathai.com) because it has fewer side effects and can replace injections, with treatment outcomes comparable to allergy shots.
- Subcutaneous immunotherapy is suitable for patients allergic to more than one allergen. It involves injecting small amounts of allergens under the skin, gradually increasing the dose and extending intervals from weekly to monthly to build immunity against allergens. This method should be supervised by specialists due to possible side effects such as severe allergic reactions (anaphylaxis) since allergens are injected directly into the body.
Guidelines for Allergy Treatment
