Order Cranberry Allergy Test | Berry AllergiesA cranberry allergy test measures the amount of IgE antibodies in the blood that react to cranberry proteins. It is used when a person reports symptoms after eating or handling cranberries and a clinician wants objective evidence to support or rule out a sensitization.
About Cranberry Allergy Test | Berry Allergies in Berkeley
Cranberry allergy is uncommon, but it can occur as part of a broader pattern of reactivity to fruits.
Cranberries contain proteins that the immune system can mistakenly identify as harmful. In a sensitized person, the body produces IgE antibodies specific to those proteins. When cranberries are eaten again, these antibodies can trigger the release of histamine and other mediators from mast cells, producing symptoms that may include itching, hives, swelling, stomach upset, or, in rare cases, more severe reactions.
The test itself requires only a blood sample, so it does not involve exposing the person directly to cranberry. Because IgE antibodies can also be found in people who tolerate cranberries without symptoms, results are interpreted alongside the clinical history. A positive result indicates sensitization; it does not by itself confirm that cranberries are the cause of a reaction.
Cranberry reactivity can overlap with sensitivities to other berries or fruits, and some people react to cranberry in juice, sauce, or dried forms rather than to the raw fruit. Testing is therefore most useful when the timing and type of symptoms are described clearly, allowing the result to be placed in context.
