This IgE allergy test uses a blood sample to determine if you are allergic to oats. The protein called avenin in oats is what causes allergic reactions in some people. Others may find that they are not, in fact, allergic or have an oat sensitivity, rather they may have a gluten sensitivity or celiac disease. This test is only looking for antibodies reacting to avenin, not gluten. Oat allergies are not common but reactions can result in symptoms ranging from mild to severe. Some mild reactions can become chronic over time if you come into contact with them repeatedly. These symptoms may be: Scratchy throatItchy eyesNauseaVomitingDiarrheaStomach painDifficulty breathingRash or skin irritation on and in the mouthRunny nose or nasal congestionBlotchy, irritated, itchy skinAnaphylaxis (life-threatening reaction)If you ever experience symptoms of anaphylaxis, you should seek a doctor immediately or call 911, as these can be life-threatening reactions.
