What is Blood Testing?

Blood testing is a test that measures antibodies present in your blood. This allergy test detects and measures Immunoglobulin E (IgE). IgE is an antibody that your immune system develops in reaction to a specific allergen. Other relevant blood tests include radioallergosorbent testing (RAST), eosinophil counts, or immunoassay capture test (ImmunoCAP).

Allergy blood tests usually test for ten of the most common allergy triggers, including dust, pet dander, trees, grasses, weeds, and molds. It can also detect food allergies. This test is best used for those with skin conditions that cannot complete a skin prick or patch test.

Advantages of Blood Testing

Allergy blood testing offers several key benefits:

No special preparation required
There’s no need to stop antihistamines or adjust your routine. This makes blood testing a convenient option for many patients.
Because no allergens are introduced into your skin, there is no risk of triggering an allergic reaction during the test.
Patients with eczema, psoriasis, dermatographism, or other skin issues often get more reliable results with blood testing than with skin-based tests.
The blood draw is fast and usually feels like a brief pinch.
Antihistamines and many other medications can interfere with skin prick test results—but they do not significantly affect blood test results. This makes blood testing the best choice for individuals who need to continue their medications while still getting an accurate allergy diagnosis.

Blood tests for allergies are FDA-approved. In 2022, the FDA updated this list of approvals for blood tests identifying wheat and sesame allergies.

How to Prepare For Your Blood Test

There are no special preparations for a blood test, which makes it a more convenient option for some. There is also less risk when taking this type of test. Since the lab is drawing blood and not injecting an allergen, you will not experience an allergic reaction.
