What Are Allergy Testing?


Allergy testing helps identify the exact allergens, such as pollen, dust mites, foods, or pet dander, that are causing your allergy symptoms. Whether you experience sneezing, hives, wheezing, or digestive issues, pinpointing your triggers is the first step toward lasting relief. 


At our allergy clinic, board-certified specialists with decades of experience utilize advanced testing methods to provide accurate results and personalized treatment plans.

Types of Allergy Testing We Offer

Our clinic provides a range of testing options to accurately detect allergies in both children and adults. Here are the primary types of allergy tests available at our clinic:

Patch Testing

Commonly used for contact dermatitis, this method involves applying patches of various potential allergens on the back or the arm for 48 hours.

Skin Prick Testing

This test introduces tiny amounts of allergens by gently pricking the skin’s surface using plastic prong devices. It’s quick, reliable, and widely used to test for airborne and food allergens.

Intradermal Testing

An allergist injects a small amount of allergen just under the skin. This is more invasive than skin prick testing and is only done when needed. It’s typically done if skin prick test results are unclear or for testing specific allergens like insect venom.

Common Allergens We Test For

Our tests cover a wide range of common allergy triggers, including:



  • Environmental allergens – Pollen (trees, grasses, weeds), mold, dust mites, and animal dander
  • Food allergens – Peanuts, tree nuts, eggs, dairy, shellfish, soy, wheat, and more
  • Insect stings – Bees, wasps, fire ants
  • Medications – Penicillin and other antibiotics
  • Contact allergens: – Latex, metals, fragrances, preservatives


If you suspect a trigger not listed here, our allergy care team can tailor your test accordingly.

When to Get Allergy Testing

You should consider allergy testing if you experience:


  • Chronic sneezing, congestion, or itchy eyes
  • Recurring skin rashes, eczema, or hives
  • Asthma symptoms that worsen with exposure to allergens
  • Frequent sinus infections or postnasal drip
  • Unexplained digestive issues after eating certain foods
  • Reactions to insect stings or specific environments


Early testing helps prevent symptoms from worsening and allows for faster relief.

Allergy Testing for Children

Children can safely undergo allergy testing when symptoms persist or interfere with daily life. Our allergy experts use age-appropriate methods and a gentle approach to ensure your child stays comfortable throughout the process.


Common allergy signs in children include:

  • Frequent runny noses, coughing, or ear infections
  • Eczema or unexplained rashes
  • Food intolerance symptoms, like stomach pain or vomiting
  • Trouble sleeping due to nasal congestion


Pediatric allergy testing helps your child feel better faster, improves the quality of early life, and aids in minimizing medication doses/frequency

Initial Consultation

Our allergy specialist will review your symptoms, medical history, and environment to decide on the most appropriate test.

Frequently Asked Questions

  • What should I avoid before allergy testing?

    In addition to antihistamines, which may need to be stopped 3 to 7 days prior (depending on the medication), you should also avoid topical allergy creams, certain cold medications, and alcohol. Our allergy expert will give you a specific list based on your test type.

  • Can I have allergy testing while pregnant or breastfeeding?

    Skin testing during pregnancy is generally approached with caution, though the risk of a serious reaction is very low. In many cases, especially in late-term pregnancy, your provider may discuss the risks and benefits with you and let you decide how to proceed. Blood testing is often considered a safe alternative if needed. For those who are breastfeeding, most allergy testing is typically safe, but it’s always best to review your specific situation with your doctor first. 

  • Can children outgrow their allergies? And should we retest them?

    Yes, especially with food allergies or eczema-related sensitivities. Retesting after a few years may help determine whether a child has outgrown an allergy or still needs to avoid certain triggers.

  • How often should I get allergy testing?

    Most people only need testing once unless new symptoms develop, previous results were inconclusive, or they are undergoing treatment like immunotherapy. Your allergist will recommend retesting if your condition changes over time.

  • I searched for “allergy testing near me.” What should I look for in a quality clinic?

    Searching “allergy testing near me” on Google will bring up many options, but not all clinics offer the same level of care. Look for providers who specialize in allergy and immunology, offer both pediatric and adult services, and provide multiple testing methods tailored to your symptoms. A good clinic will take the time to explain your results, offer personalized treatment options, and manage everything from seasonal allergies to complex food sensitivities.
