The prevalence of food allergy and related complaints in the general population is rather impressive. Many food allergies are clinically silent, but their long-term effects can be significant.

In addition to continued intestinal inflammation and malabsorption, systemic associations with various food allergies include thyroid disease, type 1 diabetes, neurologic disorders, and increased risk of cancer.

Food Allergy (Sensitivity) Panel: Provider Overview

Adverse Food Reactions

Adverse food reactions may occur due to a variety of reasons. In general, these reactions are subdivided into those that are immune based and non-immune based. Examples of non-immune based food reactions include:
  • Enzyme deficiencies (e.g. lactose intolerance)
  • Structural abnormalities (e.g. pyloric stenosis)
  • Other conditions (e.g. gallbladder disease, pancreatitis)
Immune-based reactions to food, or food allergies, can be classified as IgE-mediated (classical allergy) and non or mixed IgE-mediated immune reactions.

If untreated, food allergies can progress to more severe pathologies (such as celiac disease) in which the intestinal mucosa is damaged, potentially resulting in a malabsorbtive state. Symptoms of food allergy may not be exclusive to the gastrointestinal system and may involve:
  • Skin: hives, dermatitis, eczema
  • Musculoskeletal: joint pain and inflammation
  • Respiratory: sinusitis, asthma, Heiner syndrome
  • Neurologic: headache, migraine, insomnia, irritability
  • Immune: decreased immune function
  • Hematologic: anemia, blood clotting abnormalities
  • General: fatigue, weight loss
The Diagnos-Techs Food Allergy (Sensitivity) Panel (FIP) allows for identification of antibodies (salivary IgA or sIgA) to some of the most common food antigens – gluten (gliadin), milk (casein), egg (ovalbumin), and soy protein. The FIP allows for identification of specific food sensitivities, which is crucial to appropriate treatment through diet.

Tests Included in FIP:

  • Cow's milk (casein) Ab, sIgA
  • Soy protein Ab, sIga
  • Egg (ovalbumin) Ab, sIgA
  • Gluten (gliadin) Ab, sIgA
