Quick Facts
- Sample: Blood
- Fasting: No special preparation required
- Turnaround: 3-5 business days (may take longer based on weather, holiday, or lab delays)
What's Included
This test measures allergen-specific IgE antibodies to pineapple (F210-IgE Pineapple) in a blood sample. When your immune system treats pineapple proteins as a threat, it can produce IgE antibodies against them, and this test detects the presence and amount of those pineapple-specific IgE antibodies in your blood.
This is a single allergen test. It reports on pineapple only and does not measure IgE antibodies to any other food, nor does it measure IgG or any other antibody class. The result reflects IgE sensitization to pineapple as an analyte, not a diagnosis of clinical food allergy on its own.
Benefits
- Targets IgE antibodies specific to pineapple only.
- Uses a standard blood draw with no special preparation.
- Provides a specific, lab-based data point for your provider.
- Supports a focused conversation about pineapple-related symptoms.
- Results are typically available in a few business days.
Who Is This Test For?
- People who have noticed symptoms after eating pineapple or pineapple-containing foods.
- Individuals working with a healthcare provider to evaluate a possible pineapple sensitivity.
- People who want an objective, lab-based data point on pineapple-specific IgE.
- Individuals whose provider has recommended IgE testing as part of a broader evaluation.

FAQ
1. What does this test measure, and how is it different from other food allergy tests?
This test measures the level of pineapple-specific IgE antibodies in your blood, reported through the F210-IgE Pineapple biomarker. It is a single allergen IgE test, not a food allergy panel, so it does not screen for other foods or antibody classes. It differs from IgG based tests, which measure a different antibody and are used for different purposes, and from oral food challenges, which assess a real-time reaction rather than antibody levels.
2. Who should consider this test, and when?
People who have experienced symptoms after eating pineapple, or who are working with a healthcare provider to investigate a possible pineapple-related reaction, may find this test relevant. It can be useful when you and your provider want an objective IgE data point to support a broader clinical evaluation, rather than relying on symptom history alone.
3. Do I need to fast or prepare for this test?
No special preparation is required for this test. You can schedule your blood draw at your convenience without fasting or adjusting your diet beforehand.
4. How quickly will I get results?
Results are typically available within 3-5 business days after your sample is collected. Turnaround may take longer depending on weather, holidays, or other lab delays.
5. How should I interpret my results, and what if they are abnormal?
Interpretation of your pineapple IgE result depends on the specific value reported, your symptom history, and other clinical information, so results are best reviewed with a qualified healthcare provider rather than interpreted on their own. A detectable IgE result reflects sensitization to pineapple; it does not by itself confirm a clinical allergy, predict how severe a reaction might be, or mean you must avoid pineapple. If your result is outside the expected range, your healthcare provider can help place it in the context of your health history and determine whether any further evaluation is appropriate.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
Pre-test preparation
No special preparation required.
Cross-Reactivity
Cross-reactivity happens when your immune system recognizes proteins in one substance that closely resemble proteins in another, sometimes leading it to react to both. This test measures only pineapple-specific IgE as identified above, and it does not test for latex, pollens, or any of the other substances discussed below. The relationships listed here are examples, not a complete list, and they represent possible additional considerations rather than confirmed allergies. Having pineapple-specific IgE does not mean you will necessarily react to any of the items below. Depending on your symptoms, history, or previous reactions, discussing related allergen testing with your healthcare provider may be worth considering.
- Natural rubber latex: Pineapple has been associated with latex-fruit syndrome, where enzymes such as bromelain may share reactive structures with latex proteins in some individuals.
- Papaya and other papain-containing fruits: Bromelain in pineapple has been reported to cross-react with papain, a related enzyme found in papaya.
- Pollen-associated foods (profilin group): Pineapple contains a profilin protein that can share structural similarity with profilins in birch and other pollens, as well as in foods like celery, melon, and some tree nuts, which may play a role in oral allergy type reactions in pollen-sensitized individuals.
