Watching your child have a reaction to food is a stressful experience that leaves you with countless questions.

At The Allergy Institute of Chicago, we specialize in expert food allergy testing to accurately identify your specific triggers, empowering you to move forward with a confident plan for safety and health.
A Parent’s Guide: Food Allergy Testing for Children
When it comes to your child, we know that safety and comfort are your top priorities. Food allergy testing is a very common and safe procedure for children, including infants and toddlers, and provides invaluable information for their well-being.
- Is it safe for my child? Yes. Our primary method, the allergy skin test, is minimally invasive and performed in a controlled clinical setting where our expert team can monitor your child closely.
- What is the right age to test? Testing can be performed at any age, depending on the child’s history of reactions. Early diagnosis is often key to managing the allergy effectively.
- How can I prepare my child? We recommend bringing a favorite toy, book, or tablet to keep them distracted and comfortable during the short waiting period. Our staff is experienced in working with children to make the process as gentle and stress-free as possible.
How Does Food Allergy Testing Work?
The most reliable and common method for food allergy testing is the allergy skin test. This simple, direct, and highly reliable diagnostic tool involves a straightforward process:
- Application: A tiny, diluted droplet of a specific food allergen is placed on the skin, typically on the back or forearm.
- The Prick: A small, sterile device is used to make a gentle prick through the droplet. This is not a shot and is not considered painful; most children report it feels like a light scratch or a tickle.
- The Reaction: If you or your child is allergic, a small, red, mosquito-bite-like bump (called a “wheal”) will form at the site within 15-20 minutes. The size of this wheal helps us determine the sensitivity to that food.

How Accurate is Food Allergy Testing?
When performed and interpreted by a board-certified allergist, the allergy skin test is the gold standard for diagnosing food allergies. A positive skin test, combined with a history of reactions to a food, confirms an allergy with a high degree of accuracy.
It’s important to distinguish this from non-standardized “food sensitivity” tests, which are not scientifically validated. Accurate testing from an allergist is crucial to avoid unnecessary dietary restrictions and to create an effective management plan. In some complex cases, Dr. Shah may recommend a follow-up blood test or an oral food challenge to confirm the diagnosis.
Preparing for Your Food Allergy Test
To ensure the most accurate results from a skin test, the most important step is to stop all oral antihistamine medications for 5-7 days before your appointment. This includes common over-the-counter brands like Zyrtec, Claritin, Allegra, and Benadryl. When you schedule your appointment, our team will provide you with a complete list of medications to avoid.
Frequently Asked Questions (FAQ) About Food Allergy Testing
What does a positive result mean for my family’s diet?
A positive test confirms an allergy and means the food must be strictly avoided. Our team will provide comprehensive education on reading food labels, preventing cross-contamination, and creating a safe and healthy diet plan.
What is the difference between a food allergy and a food intolerance?
A food allergy is an immune system reaction that can be life-threatening. An intolerance is typically a digestive issue that causes discomfort but is not life-threatening. A skin test diagnoses true allergies.
Is the skin test painful?
No, the test is not considered painful. The pricks are very superficial. The most common sensation is some itching at the reaction sites, which subsides shortly after the test.
Are at-home food allergy tests reliable?
At-home food allergy test kits are not recommended as they are often unreliable and can lead to misdiagnosis and unnecessary food avoidance. Diagnosis should always be done by a qualified allergist.
