About Onion Allergy Test | Food Allergies in Tracy
Onion allergy is an immune-mediated reaction to proteins in the Allium genus, which also includes garlic, leeks, and shallots.
The test works by measuring IgE antibodies that bind specifically to onion proteins. When a person is sensitized, their immune system produces these antibodies after exposure. During the test, a blood sample is mixed with onion allergens, and the amount of bound IgE is quantified.
Symptoms of onion allergy can include itching, hives, swelling, stomach upset, or in severe cases, difficulty breathing. However, sensitization does not always mean a clinical allergy will occur. Some individuals may have positive IgE results without experiencing symptoms upon eating onion.
Interpretation of results should always be done by a healthcare professional. They consider the test value alongside clinical history and other findings. A negative result generally indicates no sensitization, while a positive result may support further evaluation.
