What Is Immunoglobulin E (IgE)?

IgE is a protein produced by your immune system in response to allergens—substances like pollen, dust, or certain foods. High IgE levels can signal allergies, asthma, or other allergic conditions. This test specifically measures IgE as it relates to cheese, though the clinical relevance may extend broadly to other allergens.

Why Might You Need This Test?

Your doctor may order this test if you have symptoms like hives, itching, swelling, or breathing difficulties after eating cheese or other foods. It can also help diagnose conditions like atopic dermatitis or food allergies.

How Is the Test Performed?

A blood sample is drawn from a vein in your arm. The sample is sent to a lab where it is analyzed using an immunoassay method to detect IgE antibodies. Results are compared to general reference ranges for IgE levels.

What Do the Results Mean?

Results may indicate elevated IgE if your body is reacting strongly to allergens. However, interpretation depends on symptoms, medical history, and other test results. Your doctor will discuss findings with you.

Frequently asked questions

What are the normal IgE levels?
IgE levels vary widely and are not standardized across tests. Your doctor will use your specific results in the context of your symptoms and medical history to determine if levels are elevated or concerning.
How long does it take to get results?
Results are typically available within 1–3 business days, depending on lab processing times. Follow-up with your healthcare provider is recommended for interpretation.
Can IgE levels change over time?
Yes, IgE levels can fluctuate due to allergies, infections, or immune responses. Regular monitoring may be needed if you have ongoing symptoms or conditions like asthma or eczema.
