Comprehensive food allergy test measuring IgE antibodies to 15 common allergens.
This panel measures immunoglobulin E (IgE) antibodies in the blood, indicating immune responses to specific food allergens. It helps determine if you have a food allergy and provides specific protein information if peanut, milk, or egg antibody levels are abnormal. A healthcare provider will review your results with your medical history to diagnose an allergy and prescribe treatment if needed. This test is useful for individuals experiencing allergic reactions to food, helping them and their healthcare provider understand potential triggers.

What's Included
Preparation Required
No fasting required. Continue eating your normal diet for at least 2–4 weeks before testing — avoiding suspected trigger foods can cause false negatives. Inform the clinic of any antihistamines or immunosuppressants you're taking, as these can affect results.
Biomarkers Tested
2A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.
Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
