- Advantage: Can detect allergies to a wide range of foods.
- Limitation: Can give false positives and negatives, and may not be suitable for certain individuals.
Elimination Diet
- Involves removing suspected allergens from the diet for a period of time.
- If symptoms improve, the removed foods are gradually reintroduced to identify the culprit allergen.
- Advantage: Can be effective in identifying specific allergens.
- Limitation: Time-consuming, requires strict adherence, and may not be suitable for all individuals.
Oral Food Challenge
- Involves consuming small amounts of the suspected allergen under controlled medical supervision.
- A positive reaction is indicated by the development of allergy symptoms.
- Advantage: Provides a definitive diagnosis.
- Limitation: Can be risky, especially for individuals with severe allergies.
Closing Summary
Managing food allergies involves a multifaceted approach, including allergen avoidance, dietary restrictions, and the judicious use of medications.
