About this test

IgE is the antibody involved in allergic reactions, and this test measures how much of it in your blood targets spinach. Spinach is a leafy vegetable. Sensitization is not the same as allergy, so the result is read with your history. No fasting or other prep is needed.

For adults 18 and older. Test availability varies by lab location.

Who should take this test?

For adults who want to check IgE to spinach, often after a reaction to spinach, and who plan to review the result with an allergist or other healthcare provider.

What does this test measure?

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

Spinach-specific IgE (f214)
This marker measures IgE antibodies to spinach, a vegetable. A level above the lab’s reference range shows the immune system is sensitized to it. Many sensitized people have no symptoms, so the result is read with your history.
Why it’s measured: Helps an allergist understand possible sensitization to spinach.

Questions

Anything else, our care team answers by phone, text, or email.

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

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

It does not tell you whether you will react to spinach, or how strongly. IgE shows sensitization, and many sensitized people have no symptoms. A negative result does not clear an allergy either.

Decisions about eating spinach belong with an allergist or other healthcare provider who knows your history.

No. This blood test is not for urgent reactions. Trouble breathing, swelling of the face or throat, or fainting after eating any food needs emergency care, so call 911 right away. If you have a prescribed epinephrine auto-⁠injector, use it as directed.

Once you are well, an allergist or other healthcare provider can help you decide whether testing fits and what comes next.
