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 This Test Measures
The Chocolate Allergy IgE Blood Test measures IgE antibodies to chocolate (cacao) in your blood. It is a single food allergen test, also known as a cacao allergy test.
Results are reported for two biomarkers: F093-IgE Chocolate/Cacao and F093-IgE Cocoa. Biomarkers may vary slightly between labs, so review the sample report for details.
This test measures IgE only. It does not measure IgG or other antibody classes, and it does not test other foods. An IgE result shows sensitization and is not, by itself, a confirmed clinical food allergy.
Benefits
- Measures IgE antibodies to chocolate (cacao) using a blood sample.
- Reports two IgE biomarkers: chocolate/cacao and cocoa.
- Requires no special preparation before your blood draw.
- Gives you results to review with your healthcare provider.
- Delivers results in 3-5 business days.
Who Is This Test For?
- You notice swelling of the throat, tongue, or lips after eating chocolate.
- You have had hives, stomach cramps, or vomiting and suspect chocolate.
- You experience shortness of breath or wheezing you associate with chocolate.
- You have gluten intolerance or celiac disease and react to chocolate.
- You want chocolate-specific IgE results to discuss with your healthcare provider.

FAQ
1. What does this test measure, and does it include other foods?
It measures IgE antibodies to chocolate (cacao) in your blood, reported as F093-IgE Chocolate/Cacao and F093-IgE Cocoa. No other foods or ingredients are tested, and IgG or other antibody classes are not measured. The results may help your healthcare provider evaluate IgE sensitization to chocolate.
2. Who should consider this test, and when?
Consider it when you notice symptoms you associate with eating chocolate, or when you have gluten intolerance or celiac disease and react to chocolate. Positive results should be discussed with your physician, so this test works best alongside a conversation with your healthcare provider, not as a replacement for medical evaluation.
3. Do I need to fast or prepare for this test?
No special preparation required. Your sample is a standard blood draw at a local lab.
4. How quickly will I get results?
Results take 3-5 business days. May take longer based on weather, holiday or lab delays.
5. How should I interpret my results, and what if they are abnormal?
Interpretation depends on your specific result, your history, and any symptoms you have experienced. An IgE result reflects sensitization to chocolate and cannot by itself confirm or rule out a clinical food allergy. It does not predict reaction severity or determine whether chocolate is safe for you. If a result is abnormal, review it with your healthcare provider, who can decide whether 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 may occur when the immune system recognizes similar proteins in different foods or substances. This test measures only IgE to chocolate/cacao and cocoa. It does not test for any of the items listed below, and they are not measured by this test.
Cross-reactivity involving cocoa is not well characterized, and these examples are not exhaustive. They are possible additional considerations, not confirmed allergies, and you may not react to any of them. Depending on your history, symptoms, or your healthcare provider's guidance, related allergen testing may be worth discussing.
Walnut: Laboratory findings from a reported case suggest cocoa and walnut proteins may share some IgE-binding features, although the overlap appeared partial.
Almond:A reported case found partial IgE cross-reactivity between cocoa and almond proteins, which does not mean everyone will react to both.
Brazil nut:A cocoa seed protein resembles 2S albumins found in allergenic seeds such as Brazil nut, though clinical significance has not been established.
Many reactions attributed to chocolate are linked to other ingredients or cross-contact with milk or tree nuts, so a healthcare provider can help sort out what may be relevant for you.
