The Common Respiratory Allergy Panel — Expanded panel contains 25 tests with 25 biomarkers.

The Common Respiratory Allergy Panel - Expanded is an essential test that measures the level of specific Immunoglobulin E (IgE) antibodies in your blood. These antibodies are vital in understanding whether an individual has an allergic reaction to common airborne allergens. When exposed to these allergens, an overreaction of the immune system can lead to the release of IgE and other substances like histamine, resulting in allergic symptoms.

What's Tested:

The panel screens for allergic reactions to a comprehensive array of allergens:

Weeds and Grasses:

  • 6 different types including Bermuda grass, Timothy grass, Johnson grass, Common Ragweed, Rough Pigweed, and Sheep Sorrel.

Tree Pollens:

  • 10 different types including Maple, Birch, Mountain Cedar, Oak, Elm, Walnut Tree, Cottonwood, White Ash, Hickory/Pecan, and White Mulberry.

Indoor Allergens:

  • 9 different types including Cat Dander, Dog Dander, Mouse Urine, C. Herbarum, Fumigatus, Alternata, Cockroach, Dust mite (D. Pteronyssinus and D. Farinae).

These antibodies are part of the body's immune response to specific allergens, including tree pollen. When an individual is exposed to an allergen, the immune system may respond by producing an excessive amount of the antibody known as IgE. The activation of IgE triggers the release of histamine, a substance that leads to an allergic reaction. Normally, IgE antibodies are found in minimal amounts in the blood. However, higher levels of IgE may signify an overreaction of the body to allergens. The presence of these antibodies, in conjunction with observed allergic symptoms, can be indicative of an allergy.

Importance of the Test:

  • Diagnosis of Allergies: Helps in diagnosing allergies that lead to respiratory symptoms such as sneezing, nasal congestion, itchy eyes, asthma, and other allergic reactions.
  • Personalized Treatment Plans: Assists healthcare providers in customizing treatment plans for allergic symptoms, including medications, lifestyle changes, and potential allergen avoidance or immunotherapy.
  • Understanding Seasonal vs. Year-round Allergies: Differentiates between seasonal allergies (such as pollen from grasses or trees) and perennial (year-round) allergies like pet dander or dust mites.

Who Should Consider the Test:

  • Individuals Experiencing Allergic Symptoms: Particularly those with recurring or chronic respiratory symptoms.
  • Healthcare Providers Managing Allergic Patients: To create personalized treatment plans and preventive strategies.
  • Parents of Children with Suspected Allergies: To understand and manage potential triggers.


The Common Respiratory Allergy Panel - Expanded provides a broad look at an individual's allergic responses to typical outdoor and indoor allergens. It plays a crucial role in identifying the specific substances that may be triggering uncomfortable and sometimes severe allergic reactions. By pinpointing these allergens, healthcare providers can develop tailored treatment plans, offer advice on avoidance strategies, and improve the overall quality of life for those suffering from allergies.
