Measures immunoglobulin E (IgE) antibodies to 14 common respiratory allergens to help determine allergy presence.

This test measures the level of IgE antibodies your immune system produces in response to specific tree pollen, weed, grass, and common indoor allergens. It helps you and your healthcare provider determine if you have an allergy. The panel includes weeds and grasses (Bermuda grass, Timothy grass, common ragweed, rough pigweed, sheep sorrel weed), wood tree pollen (oak, elm), and specific indoor allergens (cat dander, dog dander, mouse urine, Alternaria alternata mold, cockroach, and dust mites Dermatophagoides pteronyssinus (American), and Dermatophagoides farinae (European). A positive result does not confirm an allergy diagnosis; follow-up with your healthcare provider is crucial.

Fasting Required
No
Sample Type
Blood draw
Turnaround
5–10 business days
Common Use
Allergy mapping, elimination diet guidance

Who Is This For?

People experiencing unexplained digestive issues, skin problems, or chronic fatigue that may be food-related. Anyone with known allergies who wants comprehensive mapping of their triggers. Parents investigating potential food sensitivities in children. People considering an elimination diet and wanting data to guide which foods to remove.

What's Included

IgE and/or IgG antibody measurement
Panel of common allergens (varies by provider)
Results ranked by reactivity level

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

16
Globulin g/dL

A 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.

Bermuda kU/L

Measures IgE antibodies specific to Bermuda grass pollen.

Timothy grass IU/mL

Allergen-specific IgE antibody levels.

Ragweed kU/L

Measures IgE antibodies specific to Ragweed pollen.

Rough pigweed IU/mL

Allergen-specific IgE antibody levels.

Sheep sorrel weed IU/mL

Allergen-specific IgE antibody levels.

Oak IU/mL

Allergen-specific IgE antibody levels.

Elm IU/mL

Allergen-specific IgE antibody levels.

Cat kU/L

Measures IgE antibodies specific to Cat dander.

Dog kU/L

Measures IgE antibodies specific to Dog dander.

Mouse urine IU/mL

Allergen-specific IgE antibody levels.

ALT (Alanine Aminotransferase) U/L

A liver enzyme that helps convert proteins into energy. ALT is found primarily in the liver, making it a highly specific marker for liver damage. Elevated levels may indicate hepatitis, fatty liver disease, or medication-related liver injury.

Cockroach kU/L

Measures IgE antibodies specific to cockroach.

Dermatophagoides pteronyssinus kU/L

Measures IgE antibodies specific to Dermatophagoides pteronyssinus (dust mite).

Dermatophagoides farinae kU/L

Measures IgE antibodies specific to Dermatophagoides farinae (dust mite).

Immunoglobulin E (IgE) ng/mL

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').
