Order Onion Allergy Test | Food AllergiesAn onion allergy test measures the amount of immunoglobulin E (IgE) antibodies in the blood that are specific to onion. IgE is the antibody class most closely associated with immediate allergic reactions, so this test is used to help evaluate whether a person's symptoms may be related to an immune response to onion.
About Onion Allergy Test | Food Allergies in Lafayette
Onion is a common culinary ingredient, and reactions to it are often attributed to food intolerance rather than a true allergy.
A true onion allergy involves the immune system producing IgE antibodies that recognize proteins in onion. When onion is eaten or sometimes handled, these antibodies can trigger the release of histamine and other chemicals from immune cells, which may lead to symptoms such as hives, itching, swelling, stomach upset, or in more severe cases, breathing difficulty.
The blood test detects onion-specific IgE in a sample, which can support a diagnosis when considered alongside a person's history and symptoms. It is important to note that a positive result does not by itself confirm an allergy, and a negative result does not always rule one out. Some people may have IgE antibodies without experiencing symptoms, and others may have reactions that are not IgE-mediated.
Onion is part of the Allium genus, which also includes garlic, leeks, and chives. Some individuals with an onion allergy may also react to other alliums, though this is not universal. Because onion is present in many prepared foods, identifying the specific trigger can require careful review of ingredients and, in some cases, additional testing or specialist evaluation.
