What this test is
The Basic Food Allergy Test Panel measures food-specific IgE antibodies in the blood. IgE is an immune protein that can be involved in allergic reactions to foods. Elevated results may suggest sensitivity, but they do not by themselves diagnose a food allergy.
What it measures
- Milk-specific IgE — antibody response to proteins in cow's milk
- Wheat-specific IgE — antibody response to wheat proteins
- Shrimp-specific IgE — antibody response to shrimp proteins
- Peanut-specific IgE — antibody response to peanut proteins
- Egg white-specific IgE — antibody response to proteins in egg white
- Soy-specific IgE — antibody response to soy proteins
- Walnut-specific IgE — antibody response to walnut proteins
What the test involves
A trained phlebotomist collects a small blood sample, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this panel when a person reports symptoms after eating certain foods, such as hives, stomach upset, or breathing changes. It can help gather information alongside a medical history and other evaluations.
Preparation
Preparation instructions can vary by laboratory, so follow the specific directions provided by the collection site. Ask the lab if any medications or fasting rules apply before your sample is collected.
How results are reported
Results are typically reported as numeric antibody levels for each food, along with a qualitative interpretation such as negative, low, or elevated. Reference ranges and reporting formats differ by laboratory, so review your report with the ordering clinician.
