How testing helps detect allergies

With just one blood draw, healthcare providers have a quick and simple way to get answers about allergy symptoms.

Results from a single blood sample, along with an exam and medical history, can help healthcare providers establish an accurate diagnosis and create a treatment plan.


A powerful tool with one blood sample

Immunoglobulin E (IgE) is an antibody naturally produced by the immune system.

If a person is exposed to an allergen—a usually harmless substance like pollen, pet dander or a certain food—and their type of IgE mistakenly identifies an allergen as an “invader,” their immune system could:

  • Overreact and produce IgE antibodies that travel to cells in the body, such as cells in the skin, throat, nose or lungs
  • Release chemicals in the body that cause an allergic reaction, producing mild or severe allergy symptoms 2

An allergen-specific IgE test measures the levels of certain IgE antibodies—with just one sample of blood—to help identify which allergens may be causing unwanted symptoms.

Ask your primary care provider about testing

Anyone can request (or obtain) IgE allergy blood testing from their primary care provider—and it doesn’t matter if you are taking medication, are pregnant or have skin conditions.

A wide range of tests can identify 500+ relevant allergens—including grasses, foods, molds and animal dander—to help you get the allergy answers you need.
