Understanding IgE Reactions
IgE antibodies prompt the release of histamine and the activation of mast cells, causing the classic allergic response. Serum IgE tests can measure IgE antibody levels in the blood. Allergic reactions occur when IgE antibodies attach to specific receptors on mast cells and other white blood cells. Elevated IgE antibody levels indicate that the patient is likely to experience physiological effects from consuming foods or inhaling environmental allergens to which they are sensitive.
Although IgE is typically present in small amounts, the risk of severe reactions is thought to increase as the amount of IgE increases. Genetics are believed to play a role in the development of allergies. Exposure to microbes, various foods, and environmental allergens can also elicit an IgE response.
It is important to note that having measurable IgE for a particular allergen does not necessarily mean that you will experience allergy symptoms when exposed to it. While higher IgE levels generally increase the likelihood of having a true allergy, they do not predict the severity of allergic symptoms.
Why Test IgE Antibodies?
Eliminating foods that trigger IgE reactions can alleviate symptoms and related disorders. Our IgE antibody testing identifies specific trigger foods by measuring heightened levels of IgE antibodies associated with them. IgE testing assists health practitioners in developing personalized treatments for their patients as IgE responses may not always be immediately recognizable, making accurate testing an important complement to patient symptom reporting.
