The Comprehensive 20 Food Allergy Test Panel is a blood test that checks for allergic antibodies to 20 common foods. It is usually ordered when a person has symptoms after eating, such as hives, stomach upset, or swelling, and a food allergy is being considered.

What it measures

  • Food-specific IgE antibodies — Antibodies the immune system makes against a particular food.
  • Milk and egg proteins — Common triggers in children and adults.
  • Peanut and tree nut proteins — Frequently tested because reactions can be severe.
  • Wheat and soy proteins — Grains and legumes linked to some reactions.
  • Fish and shellfish proteins — Seafood allergens that can cause strong reactions.
  • Other foods in the panel — May include sesame, corn, and certain fruits.

Who it is for

A doctor or allergist typically orders this panel after reviewing symptoms and diet history. It is not a routine screening test for people without symptoms.

Preparation

No fasting is needed. Tell the lab about any antihistamines or other medicines you take, because some can affect results.

Results and what they mean

Results list the level of antibody for each food, often as a number or class. A high level does not always mean a true allergy, and a low level does not always rule one out. A clinician interprets results alongside your history; this is general information, not medical advice.
