What Does This Test Measure?

The test looks for IgE antibodies against a variety of foods, such as dairy, eggs, nuts, seafood, wheat, soy, and others. IgE antibodies are part of your immune system’s response to allergens, which can cause reactions like hives, swelling, or difficulty breathing in some people.

Why Might Your Doctor Order This Test?

Your doctor may recommend this test if you’ve experienced symptoms like itching, swelling, digestive issues, or breathing problems after eating certain foods. It can also help confirm allergies if you’ve had a positive skin prick test or other allergy-related symptoms.

How Is the Test Performed?

A small blood sample is taken from your arm. The blood is then sent to a lab for analysis using immunoassay methods to detect IgE antibodies against the listed foods.

What Do the Results Mean?

Positive results for IgE antibodies against specific foods suggest a possible allergy. However, IgE alone doesn’t always confirm an allergy—other tests or clinical correlation may be needed. Elevated levels in multiple foods may indicate a broader sensitivity.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How often will I need to repeat this test?
IgE antibody levels can change over time, especially if you avoid certain foods or if your immune system responds differently. Your doctor may recommend retesting if symptoms persist or if you’ve had changes in diet or health.
Can I eat or drink anything before the test?
No special preparation is needed for this test. However, if you’re taking medications that affect blood tests, let your doctor know. Avoid alcohol 24 hours before your appointment.
What if my results show IgE antibodies to foods I don’t suspect?
Elevated IgE levels to unexpected foods don’t always mean you’re allergic. Some people develop IgE antibodies without symptoms. Your doctor may recommend further testing, like an oral food challenge or elimination diet, to clarify the relationship between the food and your symptoms.
