Food allergy testing helps determine whether symptoms such as hives, vomiting, swelling, or breathing difficulty are caused by a true food allergy. A food allergy occurs when the immune system overreacts to a food protein and produces IgE antibodies, leading to reactions that can range from mild to severe. Testing provides clarity, helps ensure safety, and prevents unnecessary food restrictions.

How It Works?

• Small amounts of specific food allergens are evaluated using skin or blood testing
• The immune system’s IgE response is measured
• A reaction helps identify foods that may be causing symptoms
• Results are interpreted in the context of symptoms and medical history

Steps/Types of Food Allergy Testing

• Skin Prick Testing to specific food reagents
• Blood Test- IgE to specific foods are measured if available through blood work.
• Oral Food Challenge is the gold standard to determine if a patient has outgrown a food allergy.  It is performed under close medical supervision with small, gradually increasing amounts of the food consumed
• Confirms or rules out a food allergy when results are unclear or outgrowing is suspected

Who Should Consider This Service?

Food allergy testing may be recommended if:

• You or your child has had reactions after eating certain foods
• A child has moderate to severe eczema
• Foods are being avoided without a confirmed diagnosis
• You want to know if a known food allergy has been outgrown
