Food allergies are difficult to diagnose and often the foods causing disease are not obvious. Scientific literature indicates there are a select number of specific foods that are most often responsible. Allermetrix has constructed a comprehensive food allergy panel that incorporates data from published clinical studies and our in-house testing results. For the best diagnostic efficiency, both IgE and IgG4 antibodies must be tested to identify the offending substance(s). Often food allergy is not IgE mediated (which is responsible for immediate reactions occurring within 20 minutes of ingestion) requiring the need to assay for IgG4 reactivity (believed to be involved in delayed reactions resulting hours later).

Allermetrix reviewed over 15,000 tests submitted to the laboratory and identified the most commonly encountered positive foods. After statistical analysis of the data, 40 foods were selected for the "900" food panel.

The foods included in the 900 panel are grouped below:
Legumes: Bean (White/Navy), Pea (Green), Peanut, Soybean
Tree nuts: Almond, Brazil, Cashew, Hazelnut, Pecan, Pistachio, Walnut (English)
Fish: Specific fish only if indicated on diet history-*
Shellfish: Specific shellfish only if indicated on diet history-*
Dairy: Cow's milk
Animal: Egg/White, Egg/Yolk, Beef, Pork
Fruits: Apple, Banana, Pineapple, Grape/Raisin, Lemon, Cantaloupe/Muskmelon, Watermelon, Orange, Coconut
Seeds/Spices: Sunflower Seed, Sesame Seed, Mustard
Grains: Barley, Oat, Rye, Wheat, Gluten
Vegetables: Celery, Garlic, Onion, Tomato, Potato, Pepper (Bell)
