Using only a saliva sample, the Food Panel offers a convenient, non-invasive and economical way to screen for food allergies and sensitivities. The Diagnos-Techs Food Panel identifies antibodies to proteins in gluten (gliadin), milk (casein), egg (ovalbumin) and soy. Identifying the specific foods that your immune system reacts to can help your doctor recommend a treatment plan that is best for you.

Food Panel: Patient Overview


A food reaction is an abnormal response in the gastrointestinal (GI) system that can occur for a variety of reasons. In some cases, like lactose intolerance, there may be too little of a particular enzyme to digest a food correctly. In other cases, the immune system creates antibodies to proteins in foods. When a food reaction involves the immune system in this way, it is called a food allergy or food sensitivity.

When the immune system reacts to a food, it can lead to inflammation and irritation in the intestine each time the particular food is consumed. Food allergies and sensitivities can range in severity from immediate, sometimes life-threatening reactions (anaphylaxis) to milder symptoms such as gas and bloating.

Many food sensitivities produce minimal symptoms, yet if untreated, the long-term consequences can be serious and may involve the development of conditions in many different organ systems. The Diagnos-Techs Food Panel tests your saliva for antibodies to four of the most common food allergens.

Common Misconceptions

Food allergies are conditions of childhood. In truth, food allergies and sensitivities can be present at any age, and in some instances may be lifelong.

Food allergies are only present in symptomatic patients. In truth, food allergies and sensitivities can be silent in many individuals. The absence of symptoms, however, does not mean that inflammation and damage are not occurring.

Food allergies are simply intestinal irritations. In truth, food allergies and sensitivities cause immune reactions and may contribute to a wide range of symptoms that do not involve the intestine. It is even possible for some patients to experience only symptoms outside of the GI system.
