What is the purpose of this test?
Order this Oat Allergy Ige Blood Test to measure the IgE antibody levels in the blood to screen for an allergy to oats. Oats are cereal grains belonging to the Poaceae (Grasses)family, originating in Europe, Asia, and northwest Africa. Oats contain fiber and antioxidants, making them a popular grain crop grown globally. However, some individuals may be sensitive to oats' proteins despite their health benefits. This Oat Allergy Blood Test may help individuals screen for an adverse reaction to oats and assist their healthcare provider in developing a management and treatment plan.
What causes an allergy to oats?
Although an oat allergy is uncommon, certain individuals may be allergic to the avenin protein found in oats. Avenin, similar to gluten, induces the same adverse reactions and should not be mistaken for celiac disease. Celiac is a gluten allergy, a protein found in wheat. Oats may not contain gluten; however, they are mostly grown and processed at facilities that handle gluten products, including cereal grains like wheat, rye, and other substances. This process can cause cross-contamination between these products and trace amounts of gluten in oat products.
Consuming or coming in contact with oats or oat-based products may activate an individual's immune system response. Once a sensitized individual ingests or touches oats, the immune system will view these proteins as harmful and produce antibodies to combat these invaders. Unfortunately, these antibodies cause a chemical known as histamine to be released, triggering an allergic reaction.
Since oats are cereal grains, an individual allergic to oats may also be allergic to other grains in this family. Other grains in the grasses family include rye, wheat, triticale, barley, oat, maize, and rice. Most food allergies develop in childhood. Some individuals outgrow them over time, but many suffer from lifelong allergies.
When should I order an Oat Allergy Blood Test?
Individuals may order this test panel if they have experienced symptoms associated with an oat allergy. An allergic reaction to oats may range from mild to severe, depending on the individual. An individual may experience allergic reactions minutes to a few hours after exposure. An individual allergic to oats may experience the following symptoms:

A severe, possibly life-threatening allergic reaction known as anaphylaxis may occur in some cases. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:
- Rapid or increased pulse
- Swollen throat or lump, making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
