IgE Antibody Profile to Common Food Allergens (Screening)

What Does This Test Measure?

IgE antibodies are part of your immune system’s response to allergens. When your body detects these foods as harmful, it produces IgE antibodies to mark them for defense. This test measures the presence and levels of IgE antibodies against a mix of common food allergens, including dairy, eggs, peanuts, tree nuts, wheat, soy, fish, and shellfish.

Why Might You Need This Test?

Your doctor may recommend this test if you have symptoms like hives, itching, swelling, difficulty breathing, or digestive issues after eating certain foods. It can also help confirm allergies suspected through other methods, such as skin prick tests or elimination diets.

Your doctor will take a blood sample from a vein in your arm. You may feel a slight pinch, but it’s usually over quickly. No special preparation is needed, but inform your doctor about any medications or supplements you’re taking.

This test is typically done as part of a routine blood draw and doesn’t require fasting. Results can help guide further testing or dietary adjustments if needed.

What the Results Mean

Positive results indicate the presence of IgE antibodies to certain foods, suggesting a possible allergic reaction. However, a single test doesn’t confirm an allergy—your doctor may recommend additional testing, such as skin tests or food challenges, for confirmation.
