Do you need to fast for an allergy test
We respect your privacy. Most allergens are harmless substances like dust mites, pollens, medications, or food components to which your immune system overreacts, resulting in allergy symptoms. Allergy testing including skin testing and blood testing can identify exactly which allergens trigger your allergies. When you know what they are, you and your doctor can find the best way to help manage your symptoms. An allergy develops because your immune system produces immunoglobulin E IgE antibodies specific to a potential allergen after you are exposed to it. The next time you are exposed, the allergen — usually a protein — will react with these antibodies, triggering an allergic reaction. Blood testing for allergies looks for the presence of these antibodies.

The antibodies being tested are called IgG. As long as you have eaten a certain food within the past 4 weeks, the test should be able to detect those IgG levels. Conversely, if someone has removed a food from their diet for long periods of time, they may or may not still have IgG reactivity detected.
In general, your body will clear specific IgG antibodies not being triggered by certain foods 18 to 24 months after last exposure; however, people have been known to clear IgG both sooner and longer than those time intervals.
