Testing for allergies

Allergy testing

Testing (blood and skin) for reactions to foods, medications, insect stings, environmental allergens and more.

Food and drug allergy testing and challenges

A controlled medical procedure performed by allergists to determine whether a patient is truly allergic to a specific food or medication. A challenge test involves gradually giving a patient increasing amounts of the suspected food or drug in a controlled clinical setting. The patient is monitored closely by a medical team for any signs of an allergic reaction.

Immune system evaluations

Diagnostic evaluations for immune deficiencies.

Spirometry and FENO testing

Spirometry is a simple breathing test that measures how much air you can inhale and exhale, and how quickly you can exhale. It is commonly used to diagnose and monitor lung conditions such as asthma, COPD and other respiratory disorders. FENO (fractional exhaled nitric oxide) is a noninvasive test that measures exhaled nitric oxide, a marker of airway inflammation, helping to assess and monitor asthma control.

Treatment & management

We develop safe, personalized medical plans to manage your symptoms. These include avoidance, environmental management and, if needed, prescription medications, biologics, IgG Infusions or allergy immunotherapy (allergy shots) based on your individual symptoms and needs.

Oral immunotherapy (OIT)

OIT is a treatment that involves gradually introducing small, controlled amounts of a food allergen — such as peanut, milk or wheat — with the goal of increasing the patient’s tolerance over time. This approach can reduce the risk of severe reactions from accidental exposures and may eventually allow some patients to include the food in their diet. OIT is carefully supervised by an allergist to ensure safety and effectiveness.

Immunotherapy (allergy shots)

A long-term treatment that reduces sensitivity and provides lasting relief.

Specialty programs

Integrated care for complex conditions through programs like the Comprehensive Sinus and Allergy Program.

Collaborative care

Our team works closely with your primary care physician and other specialists — such as pulmonologists, dermatologists and ENT doctors — to deliver coordinated care. We also collaborate with Endeavor Health experts in the Comprehensive Sinus and Allergy Program, providing you with access to advanced diagnostics and therapies when needed.

As one of only seven UCARE-designated health systems in the U.S. — and the only one in Illinois — we are recognized as a center of excellence for the treatment of urticaria (hives).

Frequently asked questions

What is allergy and immunology care?

This specialty focuses on the diagnosis and treatment of allergies, asthma and disorders of the immune system. It includes evaluating symptoms, conducting allergy tests and creating long-term treatment plans.

What are allergy shots and how do they work?

Allergy shots, or immunotherapy, gradually reduce your immune system's response to environmental allergens. Over time, they can provide lasting relief, even after treatment ends.

Do I qualify for allergy testing or injections?

If you experience recurring symptoms such as sneezing, rashes or breathing problems, or if over-the-counter treatments don’t help, allergy testing and injections may be appropriate.

What should I expect at my first visit?

Your specialist will take a detailed history, assess your symptoms and may recommend testing. Based on your evaluation, they’ll develop a personalized plan of care.
