Allergy testing not only provides much-needed relief from symptoms but also prevents its life-threatening effect, known as anaphylactic shock. While allergy symptoms may appear similar across types, allergens (allergic reaction triggers) vary. Our Allergen Profiles are categorized based on these triggers, making it easier for your healthcare provider to perform a proper diagnosis and prescribe treatment. 

You can order online allergy tests and visit one of our over 4,000 affiliated locations nationwide for convenient allergy testing near you.

What Are Allergies?

Allergies occur when the immune system overreacts to normally non-threatening substances or allergens. When exposed to an allergen, the body produces antibodies like immunoglobulin E (IgE) that activate the release of chemicals like histamine, causing allergy symptoms. Common allergen sources include:

  • Environmental – Dust mites, pet dander, pollen, mold
  • Food – Milk, eggs, peanuts, shellfish, wheat
  • Medications – Penicillin, aspirin, chemotherapy drugs
  • Insect stings – Bees, wasps, hornets

What Is The Role of Allergy Testing

Allergy blood tests help identify the specific triggers of allergic reactions–whether they are environmental allergens like dust, pollen, and insects, or food substances, certain chemicals, and medications. By knowing the source of your allergy, you’ll have better control of your health as you understand what to avoid and how to address the allergy through recommended treatment.

With over 100 million Americans experiencing allergies in a year, allergy blood test has never been more crucial, especially in detecting and classifying the type of allergies. The most common conditions linked to allergies include:  

  • Hay fever – Affects up to 10% of adults and 40% of children
  • Asthma – Affects over 25 million Americans

When To Do Allergy Testing

Allergy blood tests should be taken as soon as possible, preferably at the onset of symptoms. Allergies left untreated can worsen, which can have dire consequences for your health. Anaphylaxis is a severe reaction that must be treated quickly to avoid complications that can be life-threatening. Having access to allergy testing near you is important because you get important information you can use to help manage your allergy and prevent those serious complications.

Understanding Allergy Test Results

Properly interpreting allergy testing results is the way to proper diagnosis and treatment. Allergists look at:

  • The size of the skin test wheal – Larger means greater reaction
  • The levels of allergen-specific IgE in the serum in kU/L units
  • Clinical history of symptoms upon allergen exposure

IgE levels above 0.35 kU/L generally signify an allergy, although lower levels can also trigger symptoms. The higher the IgE level, the more serious the allergy tends to be.

Classifying the severity of reaction using a scale from 1 to 6 helps gauge treatment approaches:

  • Grade 1-2 – Mild reaction, treated with avoidance
  • Grade 3-4 – Moderate reaction, may need medications
  • Grade 5-6 – Severe reaction, requires emergency medication
