Food Allergy Test

What is a Food Allergy Test?

Around 32 million Americans suffer from at least one type of food allergy.  Food allergies are the results of your body's immune system mistakenly identifying certain types of food as harmful.  The immune system releases IgE antibodies which trigger the release of a chemical called histamine.  Histamine causes the symptoms commonly associated with an allergic reaction.  Food allergies often develop when a person is younger but they can also appear later in life.  Sometimes a person grows out of them and sometimes they persist for life.  Since it can be difficult to narrow down which foods you are allergic to, simple blood testing is a quick and easy way to find out what you are allergic to and how severe that allergy is.  IgE blood allergy tests can be done for specific types of food or categories such as meat, dairy, seafood, or shellfish.  

What are the symptoms of a Food Allergy?

Food allergy testing can be done at any time but if you experience symptoms after eating a particular type of food, it is a good idea to get tested and find out what types of food are giving you a problem.  Reactions to food allergies can range from mild to severe.  Common symptoms include tingling or itching in the mouth, nausea, diarrhea, vomiting, swelling of the lips, tongue, or face, hives, rash, dizziness, wheezing, and difficulty breathing.  In some cases, a severe allergic reaction can result in anaphylaxis which can cause swelling in the throat, restricted breathing, rapid pulse, a severe drop in blood pressure, and loss of consciousness.

How quickly can I get results from a Food Allergy Test?

Most food allergy blood tests typically see results in about 3-5 business days.  Request A Test will notify you by email as soon as your results are ready.  You can then review your results by logging in to your private online account.  Results are straightforward and should be easy to understand.  However, Request A Test representatives are happy to answer your questions.  Just call our office during regular business hours at 1-888-732-2348 or reach us by email at
