A cranberry allergy test is a blood test that looks for immune proteins (IgE antibodies) that may react to cranberry. It is usually ordered when a person has had symptoms such as hives, itching, swelling, or stomach upset after eating cranberry or cranberry-containing products.

What it measures

  • Cranberry-specific IgE — Amount of antibody in your blood that binds to cranberry proteins.
  • Total IgE — Overall level of allergy-related antibody in your blood.
  • Related food IgE panel — Optional check for other fruits or foods that may cause similar reactions.

Who it is for

A doctor or allergist typically orders this test after a history of possible reactions to cranberry. It may also be used when other fruit allergies are being evaluated.

Preparation

No fasting is usually required. Tell your clinician about all medicines you take, especially antihistamines, because they can affect allergy test results.

Results and what they mean

Results are reported as a level or class for cranberry-specific IgE, along with a reference range from the lab. A clinician interprets the result together with your symptoms and history. This is general information only and is not medical advice; discuss your results with a qualified clinician.

Frequently asked questions

Do I need to stop eating cranberry before the test?

Follow your clinician's instructions. In many cases you do not need to change your diet, but they may ask you to avoid the food for a short time.

How long does it take to get results?

Typical turnaround is 1 to 3 business days after the blood sample reaches the lab.

Can this test prove I am allergic to cranberry?

No single test proves an allergy. Results are used with your symptom history, and sometimes other tests, to guide care.

Is the blood draw painful?

You may feel a brief pinch when the needle goes in. The sample is usually taken from a vein in your arm.
