What this test is
This test measures specific IgE antibodies in the blood, which are part of the immune system's response to allergens. It is a laboratory method that can support a clinician's evaluation of allergies when used alongside a person's history and other findings.
What it measures
- Total IgE — Overall level of IgE antibodies in the blood
- Specific IgE to foods — Antibody response to individual food allergens such as milk, egg, peanut, or wheat
- Specific IgE to pollens — Antibody response to tree, grass, or weed pollens
- Specific IgE to molds — Antibody response to common indoor and outdoor molds
- Specific IgE to pet dander — Antibody response to proteins from cats, dogs, or other animals
- Specific IgE to dust mites — Antibody response to microscopic dust mite allergens
- Specific IgE to insect venoms — Antibody response to stings from bees, wasps, or similar insects
What the test involves
A healthcare professional collects a small blood sample, usually from a vein in the arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order allergy testing to help investigate symptoms such as sneezing, itching, hives, or digestive upset that could be related to allergens. It is typically used as one part of a broader evaluation, not as a stand-alone diagnosis.
Preparation
Preparation needs can vary, so follow the instructions provided by the collection laboratory. Ask the lab whether any medications or foods should be avoided before the sample is taken.
How results are reported
Results are reported as levels of specific IgE antibodies for each allergen tested, often with a qualitative interpretation such as negative, low, or high. Reference ranges and reporting formats differ between laboratories, so results should always be interpreted in the context of the lab's own ranges and a clinician's assessment.
Before you go
- Whether any medications should be stopped before the test
- Which allergens are included in the panel being ordered
- How and when results will be shared with you or your clinician
