Identify foods that may be causing uncomfortable or ongoing reactions with food allergy testing. Dr. Ryan E. Stern, MD, our board-certified ENT, offers a detailed evaluation to diagnose immune responses and guide safer eating choices.
Identify Foods That Trigger Allergic Reactions
Food allergy testing is used to identify foods that trigger immune reactions in your body. During testing, your response to specific food proteins is measured to determine whether certain foods are causing symptoms such as swelling, digestive upset, hives, or nasal congestion. Dr. Stern uses these results to separate true food allergies from food sensitivities or other conditions. By clearly identifying problem foods, testing helps guide safer dietary choices.
What Does Food Allergy Testing Identify?
Food allergy testing helps determine whether your immune system is reacting abnormally to specific foods, which can trigger various symptoms. These occur when your immune system mistakenly identifies certain food proteins as harmful, leading to uncomfortable or even serious symptoms. Identifying true food allergies is important for avoiding unnecessary dietary restrictions.
The results from testing often point to one or more of the following triggers:
- Dairy-based foods and milk proteins
- Eggs and egg-containing products
- Peanuts and tree nuts
- Wheat and gluten-containing foods
- Soy-based products
- Shellfish and fish
Key Benefits of Food Allergy Testing
Food allergy testing provides clarity when symptoms are hard to connect to specific foods. By identifying true allergies, testing supports smarter, more personalized care.
- Confirms which foods trigger immune reactions
- Reduces guesswork around dietary restrictions
- Helps prevent accidental exposure to problem foods
- Supports safer meal planning and nutrition choices
Your Food Allergy Testing Experience
Your food allergy testing experience begins with a detailed consultation with Dr. Stern, during which you discuss your symptoms, diet, and any reactions you’ve had after eating certain foods. Dr. Stern reviews your history, medications, and overall health to determine whether food allergy testing is appropriate and which testing methods will provide the most accurate answers.
Scratch Test
The scratch test, also known as a skin prick test, is one of the most common methods for evaluating immediate food allergies. During this test, small drops of food extracts are placed on your skin, typically on your forearm or back, and the surface is gently scratched so the allergen enters the top layer of skin. Dr. Stern closely monitors the area for signs of a reaction, such as redness, swelling, or itching. These responses usually appear within 15 to 20 minutes.
Patch Test
Patch testing is used to detect delayed food-related reactions that don’t show up right away. Small patches containing specific food allergens are applied to your skin and left in place for 48 hours. During this time, you’ll go about your normal daily routine while avoiding activities that could dislodge the patches. When you return, Dr. Stern examines the skin for delayed inflammation or irritation, which can indicate a sensitivity contributing to chronic symptoms.
Injection Test
For select cases, an injection test offers additional insight. This method delivers a very small amount of a food allergen just beneath the skin rather than on the surface. Because the allergen reaches a deeper layer, reactions may be more pronounced and easier to interpret. Dr. Stern carefully monitors your response to safely confirm food-related immune sensitivities.
