What this test is

The Comprehensive 20 Food Allergy Test Panel is a blood test that measures immunoglobulin E (IgE) antibodies to 20 different foods. It helps identify which foods may trigger allergic reactions. The panel includes common allergens such as milk, eggs, peanuts, wheat, soy, fish, shellfish, and tree nuts.

What it measures

  • Milk IgE — reflects sensitivity to cow's milk proteins
  • Egg IgE — reflects sensitivity to egg white or yolk proteins
  • Peanut IgE — reflects sensitivity to peanut allergens
  • Wheat IgE — reflects sensitivity to wheat proteins
  • Soy IgE — reflects sensitivity to soy proteins
  • Fish IgE — reflects sensitivity to various fish species
  • Shellfish IgE — reflects sensitivity to shrimp, crab, and other shellfish
  • Tree Nut IgE — reflects sensitivity to walnuts and other tree nuts

What the test involves

A healthcare professional collects a small sample of blood from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this panel when a person has symptoms that suggest a food allergy, such as hives, digestive issues, or breathing problems after eating. It can also be used to help monitor known food allergies or guide an elimination diet.

Preparation

Preparation instructions are set by the collection laboratory. Follow the lab's instructions, which may include fasting or avoiding certain medications before the test.

How results are reported

Results are typically reported as a numerical value for each food-specific IgE, often with a qualitative interpretation such as negative, low, moderate, or high. Reference ranges vary by laboratory, so your results should be interpreted in the context of the lab's own ranges and your clinical history.

Before you go

  • Whether any medications you take could affect the test results
  • If fasting or other preparation is required before the blood draw
  • How long it will take for the laboratory to report your results
