About this test

IgE is the antibody involved in allergic reactions, and this test measures how much of it in your blood targets coconut. Coconut is botanically a fruit. 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 coconut, for example after a reaction to coconut foods or products, or ahead of an allergist visit.

What does this test measure?

The result shows whether your immune system has made IgE to coconut. An allergist reads it with your history to understand what that sensitization may mean.

Coconut-specific IgE (f36)
IgE is the antibody involved in allergic reactions. This marker is the amount of IgE in your blood that recognizes coconut, reported in kU/L. A level above the lab’s reference range means sensitization, not necessarily allergy.
Why it’s measured: Checks for IgE sensitization to coconut, often after a reaction to coconut foods or products.

A reaction after a meal can have more than one possible cause, so testing coconut on its own gives an allergist one more piece of information to read with your history.

A positive result shows sensitization, not that coconut caused your symptoms. Decisions about eating it belong with an allergist.

Not on its own. A positive result means your immune system has made IgE to coconut, 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 coconut 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. Not for emergencies: if you think you may be having a medical emergency, call 911.
