Using Blood Testing for Food Allergy Diagnosis

Blood allergy testing is one way to determine which allergens are causing an allergic reaction. While an allergy sufferer may certainly have their suspicions, an accurate test will offer greater precision in the diagnosis. Once diagnosed, your allergist can then determine the best treatment plan to reduce the risk and aggravation to you or your child. A short visit to an allergy clinic in Atlanta or the surrounding area, and you can gain a far greater understanding of your allergy.

How Does an Allergy Blood Test Work?

An allergic reaction to a particular food occurs when your body mistakenly perceives a threat. Your immune system responds to proteins in foods such as peanuts, shellfish, eggs and more by releasing antibodies called Immunoglobulin E (IgE). The IgE in your system leads to the release of chemicals that cause the symptoms of an allergic reaction.

A blood test measures the levels of IgE antibodies in your system. It is natural to have some IgE antibodies present, but higher levels indicate an allergy. While there are various blood tests available, a test like the enzyme-linked immunosorbent assay (ELISA) can identify specific allergens. Understanding the source of an allergy makes the treatment of the problem far easier. A rapid allergy diagnosis is particularly crucial when there is a risk of anaphylaxis.

What Is the Allergy Blood Test Process Like?

A blood test conducted at one of our clinics in Atlanta, Canton, Duluth and other Georgia locations is a quick process. A sample of blood will be taken from your arm with little to no pain in most cases. The sample of blood can then be sent to a testing laboratory for analysis. After test results are confirmed, your allergist can inform you of the findings and discuss appropriate treatments. Unlike some other food allergy tests, in preparing for a blood test you usually will not need to stop any medications.

Alternative Food Allergy Tests

A blood test is a common approach for diagnosing food allergies. A disadvantage with this approach is the waiting time to get results. Your allergist may recommend a skin prick test or oral food challenge as an alternative. A skin prick test offers almost immediate results by applying allergens just beneath the surface of the skin and monitoring the reaction. The oral food challenge involves consuming the suspected allergen under the allergist’s supervision in gradually increasing quantities – a minor reaction to the food substance confirms an allergy.
