About this test

This blood test measures IgE antibodies to passion fruit, a fruit. People often check it after a reaction to passion fruit, or before seeing an allergist. Sensitization is not the same as allergy, so the result is read with your history. There is nothing to do ahead of your visit.

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 passion fruit, for example after a reaction to passion fruit, or ahead of an allergist visit.

What does this test measure?

The result shows whether you are sensitized to passion fruit. With your history, it can help an allergist or other healthcare provider decide whether further evaluation makes sense.

Passion fruit-specific IgE
Specific IgE is an antibody the immune system can make against a single food. This marker measures IgE that recognizes passion fruit, a fruit. 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 passion fruit, often after a reaction to passion fruit.

Passion fruit is a tropical fruit that can cross-⁠react with latex. People sensitized to natural rubber latex can also show IgE to some of these foods, and the reverse can happen too.

An allergist reads latex and food results together with your history. A positive result shows sensitization, not that you will react to passion fruit.

Not on its own. A positive result means your immune system has made IgE to passion fruit, 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 passion fruit 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.

Lab tests are informational and don’t diagnose conditions on their own. Available to adults 18 and older; test availability varies by lab location. A licensed clinician reviews your order and, if appropriate, orders the test. All testing is performed at CLIA-certified laboratories.
