About this test
This blood test measures IgE antibodies to anise, a spice. People often check it after a reaction to seasoned dishes, or before seeing an allergist. A positive result shows sensitization, which is not the same as an allergy. No fasting or other prep is needed.
For adults 18 and older. Test availability varies by lab location.
Who should take this test?
This test is for adults who want to know whether they are sensitized to anise, for example after a reaction to seasoned dishes, or ahead of an allergist visit.

What does this test measure?
Your result shows your level of IgE to anise, which an allergist or other healthcare provider reads with your history to understand what sensitization may mean for you.
- Anise-specific IgE (f271)
- Specific IgE is an antibody the immune system can make against a single food. This marker measures IgE that recognizes anise, a spice. A level above the lab’s reference range shows sensitization, which an allergist reads with your history.
- Why it’s measured: Checks for IgE sensitization to anise, often after a reaction to seasoned dishes.

Anise is a spice in the mugwort cross-reaction group, along with caraway and dill. People sensitized to mugwort or birch pollen can also show IgE to some of these foods, so an allergist may read food and pollen results together.
A positive result shows sensitization, not that you will react. Decisions about eating anise belong with an allergist who knows your history.
Not on its own. A positive result means your immune system has made IgE to anise, which is called sensitization. Many people who are sensitized have no symptoms when they are exposed.
A diagnosis of allergy is made by a healthcare provider who looks at your symptoms and history along with results like this one. A negative result also does not by itself mean you are not allergic.
No. This test is not for urgent reactions. If you have trouble breathing, swelling of the face or throat, or you faint after eating any food, call 911 or get emergency care right away. If you have a prescribed epinephrine auto-injector, use it as directed.
Once a reaction has passed, an allergist or other healthcare provider can help you decide on next steps, including whether testing fits.
Both look for IgE sensitization. A skin test checks how your skin responds to a small amount of an allergen, while this test measures IgE to anise in a blood sample. In many cases the two are considered comparable.
A blood test may be preferred in some situations, such as a widespread skin condition or recent use of medicines that affect skin tests. Don’t stop or change any medicine without talking with your healthcare provider.
