Food Testing

What is food testing?

Food allergies are among the most dangerous types. The only way to truly know which foods you’re allergic to is to perform testing that helps pinpoint specific allergens. Food testing is crucial to your health and safety. 

You can avoid potentially harmful foods and prevent allergic reactions by identifying triggers. This testing helps you feel more secure about your diet and allows the allergy specialists at Allergy Associates of Utah to recommend appropriate treatments and lifestyle adjustments.

Which types of foods are most likely to cause allergies?

You can be allergic to any food, but some allergens (substances that cause reactions) are more common than others. Common types of food allergies include:

• Peanuts
• Tree nuts (almonds, walnuts, cashews)
• Milk
• Eggs
• Fish (salmon, tuna, etc.)
• Shellfish (like shrimp, lobster, and crab)
• Wheat
• Soy
• Sesame seeds

Food testing targets these specific allergens to help identify which foods may trigger your symptoms.

What does food testing involve?

Food testing typically involves two main methods: skin testing and blood testing. 

Skin testing

Skin testing, also known as a skin prick test, involves applying a small amount of the suspected allergens to your skin and gently pricking the skin with a needle. If you’re allergic to a specific food, you develop a bump or hive at the site of the prick. 

Blood testing

Blood testing measures the specific antibodies (IgE) level that your immune system produces in response to allergens. 

How do I prepare for food testing?

Preparing for food testing is simple; however, following specific guidelines to ensure the most accurate results is essential. Here are a few things to keep in mind before your food allergy test:

Avoid antihistamines and other medications

Antihistamines, including over-the-counter (OTC) allergy medications, can interfere with your test results. Avoid antihistamines for at least 5–7 days before your appointment. 

Avoid eating foods you suspect cause reactions

If you already think certain foods are causing allergic reactions, avoid them for a few days before your appointment.

Bring a list of foods you want to test

If you know of any specific foods that you believe are triggering your reactions, bring a list to help guide the testing process and make it more efficient.

Wear comfortable clothing

If you're undergoing skin testing, wear clothing that allows easy access .
