Understanding Allergy Testing
Allergy testing serves a vital role in diagnosing and managing allergies. It involves evaluating both immediate (type I) and delayed (type IV) hypersensitivity reactions. Type I reactions, which are the most common type of allergic reactions, are assessed using skin prick tests or blood tests that measure serum IgE levels. These tests help identify specific allergens that trigger allergic reactions. On the other hand, type IV reactions are evaluated through skin patch tests, which involve applying suspected allergens to the skin and monitoring for delayed reactions.
Indications for allergy testing are typically based on the failure of avoidance measures and medical management alone. When symptoms persist or the specific allergens causing the allergic reactions are unknown, allergy testing becomes crucial in identifying the triggers and guiding treatment plans. By identifying the specific allergens, healthcare providers can develop personalized treatment plans and provide targeted advice on allergen avoidance.
