What is the Allergy Testing?
Allergy testing is a method used to determine which specific substances (allergens) trigger allergic reactions in an individual. Healthcare providers can perform it using various tests, including:
- Skin Prick Test: Healthcare providers typically place small amounts of potential allergens on the skin. These occur typically the forearm or back, and lightly prick the skin. A reaction indicates an allergy.
- Blood Test (Specific IgE Test): Measures the level of IgE antibodies to specific allergens in the blood. Healthcare providers find it useful when they cannot perform skin tests.
- Patch Test: Healthcare providers apply allergens to patches, which they then place on the skin for 48 hours. Used primarily to identify contact dermatitis allergens.
- Intradermal Test: Healthcare providers inject a small amount of allergen just under the skin. More sensitive than skin prick tests but also more likely to cause false-positive results.
Allergy Testing Process
The allergy testing process generally involves:
- Initial Consultation: Discussion of symptoms, family history of allergies, and any known triggers or reactions.
- Choosing the Appropriate Test(s): Based on the consultation, the allergist selects the most suitable type(s) of tests.
- Performing the Test: Healthcare providers conduct the chosen test in a controlled environment.
- Results Interpretation: The allergist explains the results, identifying specific allergies.
- Developing a Treatment Plan: Healthcare providers create a personalized plan based on the identified allergies. This plan may include avoidance strategies, medication, or immunotherapy.
