Cocoa (F93) IgE blood Biomarker Testing
It measures IgE antibodies to cocoa to assess allergy risk, with results you can review in PocketMD and order through Vitals Vault/Quest.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
A Cocoa (F93) IgE test looks for allergy-type antibodies in your blood that react to cocoa. It is one way to assess whether cocoa could be a trigger for immediate allergy symptoms.
Because “chocolate reactions” are often caused by other ingredients (like milk, nuts, soy, or additives) or by non-allergic intolerance, this test is most useful when your history points to a true allergy pattern.
Your result is not a standalone diagnosis. It is one piece of evidence that should be interpreted alongside your symptoms and, when needed, other allergy testing and clinician guidance.
Do I need a Cocoa F93 IgE test?
You may consider Cocoa (F93) IgE testing if you get fast-onset symptoms after eating cocoa or chocolate, especially within minutes to two hours. Examples include hives, itching, lip or tongue swelling, throat tightness, wheezing, vomiting, or lightheadedness.
This test can also be helpful if you have eczema, asthma, or allergic rhinitis and you are trying to clarify whether cocoa is a meaningful trigger rather than guessing and over-restricting your diet.
You may not need this test if your symptoms are delayed by many hours, limited to bloating or nonspecific fatigue, or only happen with certain chocolate products. In those cases, other ingredients (milk, nuts, wheat, soy) or non-IgE mechanisms are often more likely.
If you have ever had a severe reaction (trouble breathing, fainting, or needing emergency care), treat that as urgent and work with a clinician on a safety plan. Testing supports clinician-directed care and risk assessment, but it does not replace medical evaluation.
This is a laboratory-developed, CLIA-validated blood test for allergen-specific IgE; results must be interpreted in clinical context and are not diagnostic on their own.

Key benefits of Cocoa F93 IgE testing
- Helps assess whether your reactions to cocoa fit an IgE-mediated allergy pattern.
- Reduces guesswork when “chocolate” symptoms could be from other ingredients or cross-contact.
- Supports risk discussions about immediate reactions and when to consider an epinephrine plan with your clinician.
- Guides smarter follow-up testing (for example, testing common co-ingredients like milk or nuts).
- Provides an objective data point to pair with your symptom timeline and exposure history.
- Can help avoid unnecessary long-term avoidance if your result is negative and your history is not convincing for allergy.
- Creates a baseline you can revisit if symptoms evolve or after clinician-directed management changes.
What is Cocoa F93 IgE?
Cocoa (F93) IgE is a blood test that measures allergen-specific immunoglobulin E (IgE) antibodies directed against cocoa proteins. IgE is the antibody class involved in immediate-type allergic reactions, where symptoms can appear quickly after exposure.
A positive result means your immune system has produced IgE that recognizes cocoa. That is called “sensitization.” Sensitization can increase the likelihood of clinical allergy, but it does not prove you will react every time or predict reaction severity.
A negative result makes an IgE-mediated cocoa allergy less likely, although no test is perfect. If your symptoms are strong and consistent, your clinician may still consider additional evaluation.
Cocoa vs. chocolate: why the distinction matters
Many people say “chocolate allergy,” but chocolate products often contain milk, soy lecithin, tree nuts, peanuts, wheat, or flavorings. Cross-contact during manufacturing can also introduce trace allergens. Cocoa (F93) IgE focuses on cocoa itself, so it is often used alongside testing for other likely ingredients.
What the test can and cannot tell you
This test estimates the likelihood that cocoa could trigger IgE-type symptoms, especially when your history fits. It cannot diagnose intolerance, migraine triggers, reflux, or delayed digestive symptoms, and it cannot replace supervised oral food challenges when those are clinically appropriate.
What do my Cocoa F93 IgE results mean?
Low Cocoa (F93) IgE levels
A low or negative result generally suggests that an IgE-mediated cocoa allergy is unlikely. If you still react to chocolate products, consider whether the trigger could be another ingredient (milk, nuts, soy) or cross-contact rather than cocoa itself. If your symptoms are delayed or mainly gastrointestinal, your clinician may discuss non-IgE mechanisms or other evaluations. Do not use a negative result to “test” large exposures on your own if you have had severe symptoms in the past.
In-range / negative Cocoa (F93) IgE levels
Most labs report this test as negative or within the reference range when cocoa-specific IgE is not detected or is below a threshold. In that setting, your clinician will usually weigh your symptom history more heavily than the number itself. If your history is weak for immediate allergy, this result often supports focusing on other causes of symptoms. If your history is strong, your clinician may consider additional testing or a supervised challenge rather than assuming cocoa is safe.
High Cocoa (F93) IgE levels
A higher positive result means you are sensitized to cocoa and that cocoa is more plausible as a trigger for immediate allergic symptoms. The result does not reliably predict how severe a reaction would be, so your clinician will still base safety advice on your past reactions and overall risk profile. If you have asthma, uncontrolled allergic disease, or a history of systemic reactions, your clinician may be more cautious. You may also need evaluation for related allergens or cross-reactivity depending on your diet and exposures.
Factors that influence Cocoa (F93) IgE
Your result is easier to interpret when it matches a clear pattern of symptoms after cocoa exposure. Total IgE levels, eczema, and other allergic conditions can increase the chance of low-level positives that do not cause real-world reactions. Medications like antihistamines do not typically change blood IgE results, but recent exposures and the timing of testing can affect how your symptoms line up with the lab. Product variability matters too: a reaction to a specific chocolate bar may reflect milk, nuts, or cross-contact rather than cocoa.

Frequently Asked Questions
What does the Cocoa (F93) IgE test measure?
It measures allergen-specific IgE antibodies in your blood that recognize cocoa. IgE is associated with immediate allergic reactions such as hives, swelling, wheezing, or vomiting soon after exposure.
Can this test diagnose a cocoa or chocolate allergy?
It cannot diagnose allergy by itself. A positive result shows sensitization, which must be matched to your symptom history. Your clinician may combine this with other testing and, in select cases, a supervised oral food challenge.
Do I need to fast before a Cocoa (F93) IgE blood test?
Fasting is not usually required for allergen-specific IgE testing. If you are drawing other labs at the same visit, follow the instructions for those tests.
If my Cocoa IgE is negative, why do I still react to chocolate?
Many reactions blamed on “chocolate” are due to other ingredients (milk, nuts, soy), cross-contact, or non-allergic triggers like reflux, migraine sensitivity, or intolerance. A negative cocoa IgE makes an IgE-mediated cocoa allergy less likely, but you should still review the pattern with your clinician.
If my Cocoa IgE is positive, does that mean I will have anaphylaxis?
No. The test does not predict reaction severity. Your clinician will base risk and safety planning on your prior reactions, asthma control, and overall allergy history.
When should I retest Cocoa (F93) IgE?
Retesting is usually considered when your clinical situation changes, such as new reactions, a long period of avoidance with a plan to reassess, or clinician-directed monitoring in a broader allergy workup. Many people do not need frequent repeats unless there is a specific decision point.
What other tests are commonly ordered with Cocoa (F93) IgE?
Common companions include IgE tests for likely co-ingredients (such as milk, peanut, or tree nuts) and sometimes a complete blood count (CBC) if your clinician is evaluating broader allergic or inflammatory patterns. Your best next step depends on what you actually ate and how quickly symptoms started.
