Extended Food Allergy Test
The Extended Food Allergy Test includes testing for:
- Egg White
- Peanut (Whole)
A food allergy is different from a food intolerance because it is an immune system response that occurs when the body mistakenly thinks that a food is harmful and then produces antibodies to fight it off. Individuals experience symptoms, such as skin inflammation or hives, gastrointestinal distress and trouble breathing, as the antibodies multiply.
The allergy blood test, which is called an immunoglobulin E (IgE) antibody test, measures the bodys immune systems response to the foods listed above. The lab measures the level of certain antibodies in the blood that may indicate a true allergic reaction.
The IgE test is typically one of many tools used to diagnose food allergies. You can bring the test results to your health-care provider, who may want to order a skin-prick test or other tests to confirm the food allergy. Alternatively, you can use the results to simply avoid any foods to which your test indicates an allergy and see if your symptoms go away.
