Learn more about the diagnostic tools used to evaluate allergy, asthma, sinus, and related concerns. Each page explains what a specific test or evaluation method may help clarify and when it may be recommended.
Allergy testing
Learn how allergy testing helps identify environmental, food, medication, and insect sting triggers behind symptoms such as congestion, hives, wheezing, swelling, or recurrent reactions.
Skin testing
Explore skin allergy testing for common triggers such as pollen, dust mites, mold, pets, and selected foods, and learn what results may help clarify.
Patch testing
Learn how patch testing helps evaluate delayed skin reactions, contact dermatitis, and rashes linked to metals, fragrances, preservatives, and other contact allergens.
Pulmonary function testing
Understand how pulmonary function testing measures breathing and helps evaluate asthma, airway obstruction, chronic cough, wheezing, and shortness of breath.
Lab testing
Learn when allergy blood testing and other lab tests may support diagnosis of food allergy, environmental allergy, immune response patterns, and related concerns.
Imaging
Explore how imaging may help evaluate sinus disease, chronic congestion, structural concerns, and symptoms that need a more complete diagnostic picture.

Q1. When should allergy testing be considered?
Allergy testing is often considered when patients have recurrent or persistent respiratory symptoms, skin rashes, repeated infections, or reactions to foods, medications, or insect stings.
Q2. What types of allergy tests are commonly used?
Common allergy tests include skin prick testing, blood testing for allergen-specific IgE, and in selected cases oral food challenge testing.
Q3. Can allergy testing tell exactly what I am allergic to?
Testing can help identify likely triggers, but results need to be interpreted together with your symptoms and medical history.
Q4. Can blood test results alone diagnose allergies?
No. Blood test and skin test results alone do not diagnose allergies without the clinical history.
Q5. What is patch testing used for?
Patch testing is used to help evaluate delayed skin reactions, including contact dermatitis concerns.
Q6. What is pulmonary function testing?
Pulmonary function testing measures how well the lungs are working and may help evaluate asthma and other breathing-related symptoms.
Q7. Why does diagnosis matter before treatment?
A clear diagnosis helps match the patient with the most appropriate treatment, avoid unnecessary therapies, and improve long-term care planning.
