Kiwi Specific IgE Test
The Kiwi Fruit Allergy Test measures IgE antibodies to kiwi proteins. Kiwi allergy can cause oral itching, skin reactions, and in some people more significant symptoms, and testing helps assess sensitization.

Quick answer
The Kiwi Fruit Allergy Test detects IgE antibodies against proteins in kiwifruit. Kiwi is a common fruit allergen, and reactions range from itching or tingling in the mouth to hives and, less often, more serious symptoms. Some people react to fresh kiwi because of cross-reactive proteins shared with pollen such as birch or latex. The test helps assess whether an allergic sensitization to kiwi is present.
What this test measures
Kiwi allergy is caused by proteins in the fruit that the immune system recognizes as allergens. Several kiwi proteins have been described, including actinidin and thaumatin-like proteins. Sensitivity can develop at any age, and some people with pollen allergy react to kiwi because of similar protein structures.
The test measures specific IgE antibodies to kiwi in a blood sample. A detectable level indicates sensitization, which may or may not be accompanied by symptoms. Because cooked or processed kiwi can behave differently from fresh fruit, the clinical history is an important part of interpretation.
Testing may be considered when someone reports itching, tingling, hives, or swelling after eating kiwi, or when a clinician is evaluating possible cross-reactions with birch pollen or latex. A qualified healthcare provider should interpret the result and provide guidance on management.
- Kiwi fruit-specific IgE antibodies
- Quantitative sIgE concentration reported in kU/L
- Allergen-specific IgE class on a graded scale
- Total serum IgE when included
- Blood eosinophil count when included
- Cross-reactive pollen or latex markers when a panel is included
Why people order this test
- Assess sensitization after reactions to fresh or processed kiwi
- Help evaluate oral itching, hives, or swelling after eating kiwi
- Add objective information when a fruit allergy is suspected
- Check for cross-reactivity with birch pollen or latex
- Support a clinician's allergy management plan
- Provide context when kiwi appears in smoothies or desserts
How to prepare
No fasting is required for this blood test. Follow the collection instructions provided by the laboratory, and note which forms of kiwi were eaten and how soon symptoms appeared.
Understanding your results
Results are usually available within one to three business days. A detectable level indicates sensitization to kiwi, but not everyone who is sensitized develops symptoms. A qualified healthcare provider should interpret the findings with the reaction history.

Frequently Asked Questions
What are common kiwi allergy symptoms?
Symptoms can include itching or tingling in the mouth, lip swelling, hives, stomach discomfort, and in some cases breathing difficulty. Severe reactions require urgent medical care.
Can kiwi allergy be related to pollen allergy?
Yes. Some people with birch pollen allergy react to kiwi because the proteins are similar, a pattern known as cross-reactivity.
Is cooked kiwi safer than raw kiwi?
Heating can change some fruit allergens, but reactions vary by person. A healthcare provider can advise on what is appropriate for an individual.
How is kiwi allergy managed?
Management usually focuses on avoiding the trigger and having a plan for reactions. A qualified healthcare provider should give individualized guidance.
Does a positive test always mean symptoms will occur?
No. A positive test shows sensitization. Whether symptoms occur depends on the person, the amount eaten, and how the fruit is prepared.
