Cacao Chocolate F93 IgG (F93) Blood
It measures IgG antibodies to cacao/chocolate (F93) to support food-sensitivity context and next steps, with easy ordering and Quest draw access via Vitals Vault.
This panel bundles multiple biomarker tests in one order—your report explains how results fit together.
A Cacao Chocolate F93 IgG test looks for IgG antibodies your immune system has made that bind to cacao/chocolate proteins. People usually order it when they suspect chocolate is linked to symptoms that feel “delayed,” such as bloating, changes in stool, skin flares, headaches, or fatigue that show up hours to a day after eating.
This test is not the same as an IgE allergy test. IgE is used for immediate-type allergy risk (like hives, wheeze, or anaphylaxis), while IgG is more often used as a clue to exposure and possible sensitivity patterns.
Your result is most useful when you interpret it alongside your symptoms, your diet history, and a structured trial (such as a time-limited elimination and reintroduction) guided by a clinician.
Do I need a Cacao Chocolate F93 IgG test?
You may consider this test if you notice a consistent pattern where chocolate or cacao-containing foods seem to correlate with symptoms that are hard to pin down. Common reasons people test include recurring digestive discomfort, eczema or acne flares, headaches, brain fog, or “I feel off” days that do not happen immediately after eating.
This test can also be helpful if you are already doing a food diary or elimination diet and want a data point to prioritize what to trial first. It is most practical when you have regular exposure to cacao/chocolate, because antibodies can be harder to interpret if you rarely eat the food.
You may not need IgG testing if your concern is an immediate allergic reaction (rapid hives, swelling, throat tightness, wheezing, vomiting right after eating). In that case, an IgE test and clinician evaluation are more appropriate, and you should not use an IgG result to decide whether a food is “safe” in an allergy sense.
Testing can support clinician-directed care, but it does not diagnose a food allergy or any single condition on its own.
This is a blood antibody test typically performed in a CLIA-certified laboratory; results are for education and clinical context and are not a standalone diagnosis.

Key benefits of Cacao Chocolate F93 IgG testing
- Gives you an objective data point about immune reactivity to cacao/chocolate proteins.
- Helps you prioritize which foods to trial first if you are planning an elimination and reintroduction.
- Adds context when symptoms are delayed and do not clearly match a single meal.
- Can reduce guesswork by distinguishing “possible sensitivity signal” from random day-to-day symptom noise.
- Supports a more targeted conversation with your clinician or dietitian about diet changes and monitoring.
- Pairs well with IgE testing when you need to clarify immediate allergy risk versus non-IgE patterns.
- Creates a baseline you can compare against if you retest after a sustained diet change.
What is Cacao Chocolate F93 IgG?
Cacao Chocolate F93 IgG is a lab test that measures immunoglobulin G (IgG) antibodies in your blood that bind to cacao/chocolate antigens (often labeled “F93”). IgG antibodies are part of your adaptive immune system and commonly reflect exposure to a substance. In food testing, IgG is sometimes used as a marker that may correlate with sensitivity patterns in some people, but it is not considered a definitive test for food intolerance or allergy.
A key point is that IgG results do not tell you whether you will have an immediate allergic reaction. They also do not prove that cacao is the cause of your symptoms. Instead, they can be used as one piece of evidence to guide a structured trial: remove the food for a defined period, track symptoms, and then reintroduce it in a controlled way to see whether the pattern repeats.
Because “chocolate” foods can include many ingredients besides cacao (milk proteins, soy lecithin, nuts, gluten-containing additives, emulsifiers, and high sugar), your symptoms may come from something else in the product. That is why it helps to interpret this marker alongside your actual exposures and, when appropriate, additional testing.
IgG vs IgE: why the distinction matters
IgE testing is used for immediate-type allergy evaluation and is the right direction when reactions are rapid and potentially dangerous. IgG testing is generally used for delayed or nonspecific symptoms and for pattern-finding, not for determining whether you can safely eat a food in an allergy context.
What “F93” refers to
F93 is a standardized laboratory code used by some labs to identify the cacao/chocolate antigen used in the assay. Your report may show a numeric value, a class/category, or both, depending on the lab method.
What do my Cacao Chocolate F93 IgG results mean?
Low or negative Cacao Chocolate F93 IgG
A low or negative result means the lab did not detect a meaningful IgG antibody signal to cacao/chocolate in your sample. This often suggests cacao is less likely to be a driver of delayed symptoms, especially if you eat cacao regularly. However, a low result does not rule out reactions to other chocolate ingredients (like milk, soy, or nuts) or non-immune triggers such as caffeine, sugar alcohols, or high fat content. If you rarely consume cacao, IgG may be low even if you feel unwell when you do eat it.
In-range or mild Cacao Chocolate F93 IgG
Many labs report a middle range that may be labeled “low positive,” “borderline,” or a lower class. In this zone, the result is best treated as a weak signal that may or may not matter clinically. Your symptom pattern and exposure history become the deciding factors: if symptoms reliably follow cacao intake, a short elimination and re-challenge can clarify relevance. If you have no symptoms with cacao, a mild IgG finding alone is usually not a reason to avoid the food.
High or strongly positive Cacao Chocolate F93 IgG
A high result indicates a stronger IgG antibody signal to cacao/chocolate antigens. This can occur with frequent exposure, and it may correlate with sensitivity patterns in some people, but it still does not diagnose an allergy. If your symptoms are consistent and you want to test causality, a clinician-guided elimination (often 2–6 weeks) followed by a deliberate reintroduction is a practical way to interpret a high result. If you have immediate reactions or any history of severe reactions, do not use IgG to make safety decisions—seek IgE-focused evaluation.
Factors that influence Cacao Chocolate F93 IgG
How often you eat cacao/chocolate can affect IgG levels, because antibodies can reflect ongoing exposure. Gut inflammation, recent infections, and overall immune activity may also shift antibody patterns, which is one reason results should be interpreted in context rather than in isolation. Cross-contact and mixed ingredients matter: a “chocolate” product may contain dairy, soy, wheat, or nuts that are the true trigger. Medications that affect immune function and major diet changes can also influence results and are worth noting when you review your report.

Frequently Asked Questions
Is a cacao/chocolate IgG test the same as a chocolate allergy test?
No. IgE testing is used for immediate-type allergy risk, while IgG testing is generally used for pattern-finding in possible delayed sensitivities. A positive IgG result does not mean you have an allergy or that a food is unsafe to eat.
Do I need to fast for a Cacao Chocolate F93 IgG blood test?
Fasting is usually not required for IgG antibody testing. If you are combining this with other labs (like lipids or glucose), follow the fasting instructions for the full set of tests you ordered.
How long after avoiding chocolate should I retest IgG?
If you are retesting to see whether levels change with avoidance, many people wait at least 8–12 weeks because antibody patterns can shift slowly. The most useful “retest” is often a symptom-based reintroduction trial, ideally planned with a clinician.
If my F93 IgG is high, should I stop eating chocolate completely?
Not automatically. A high IgG result is a stronger signal, but it still needs to match your real-world symptoms to be meaningful. If you suspect a link, a time-limited elimination followed by a controlled reintroduction is a more reliable way to decide what to do long term.
Could my symptoms be from something in chocolate other than cacao?
Yes. Many chocolate products contain milk, soy lecithin, nuts, gluten-containing additives, and high amounts of sugar or caffeine-like compounds. If your IgG to cacao is low but symptoms persist, it can be worth evaluating other ingredients or considering IgE testing when reactions are immediate.
Can kids get this test?
Children can have IgG testing, but whether it is appropriate depends on the clinical question and the child’s symptoms. For suspected allergy (especially immediate reactions), pediatric evaluation and IgE-focused testing are usually the priority.
