It measures IgG antibodies to broccoli (F260) to support food-sensitivity discussions, with easy ordering and Quest-based labs through Vitals Vault.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
Broccoli F260 IgG is a blood test that looks for IgG antibodies your immune system has made that can bind to broccoli proteins. It is most often used when you are trying to connect food exposures with longer-term, non-urgent symptoms.
This test is different from classic “food allergy” testing. IgG results do not diagnose an allergy, and they do not prove that broccoli is the cause of your symptoms. They can, however, give you a structured data point to discuss with your clinician when you are planning an elimination-and-rechallenge approach.
Because food antibody results are easy to over-interpret, the most useful way to use this test is in context: your symptoms, your diet pattern, and whether you are also checking IgE (immediate allergy) or other conditions that can mimic food reactions.
Do I need a Broccoli F260 IgG test?
You might consider Broccoli F260 IgG testing if you notice repeat, delayed symptoms that seem to track with meals but are not clearly tied to a single food. Common reasons people look into IgG food testing include bloating, irregular stools, headaches, skin flares, or “brain fog” that shows up hours to a day after eating.
This test can also be helpful if you are already doing a targeted elimination diet and you want a baseline before you remove broccoli (or before you reintroduce it). If broccoli is a frequent part of your diet, an IgG result may reflect exposure rather than a problem, so pairing the result with a symptom diary matters.
You generally should not use an IgG result to decide whether you need emergency precautions. If you have immediate hives, swelling, wheezing, vomiting soon after eating, or a history of anaphylaxis, IgE-based allergy evaluation is the safer, more appropriate path.
Testing is most useful when it supports clinician-directed care and a clear plan for what you will do with the information (for example, a time-limited elimination and a structured rechallenge), rather than self-diagnosis.
This is a CLIA laboratory blood test; results are intended for clinical interpretation and are not, by themselves, diagnostic of food allergy or disease.

Vitals Vault lets you order Broccoli F260 IgG as part of a food antibody panel or as a targeted add-on when you and your clinician are narrowing down triggers. You can choose the option that fits your question: a single data point for a focused experiment, or broader coverage if you are comparing multiple foods.
After your blood draw, you get a clear lab report and a place to keep results organized over time. If you want help thinking through next steps, PocketMD can help you turn the number into a practical plan to discuss with your clinician, including what to retest and what companion tests may clarify the picture.
If your goal is to reduce guesswork, the biggest value comes from using your result alongside symptoms, timing, and exposure frequency, then retesting only when it would change your plan.
- Order online and keep results in one place for trend tracking
- PocketMD guidance for interpreting results in context
- Quest-based lab access for convenient local blood draws
Key benefits of Broccoli F260 IgG testing
- Gives you a measurable data point about immune reactivity to broccoli proteins (IgG binding).
- Helps you prioritize which foods to trial in a time-limited elimination-and-rechallenge plan.
- Adds structure when symptoms are delayed and hard to connect to a specific meal.
- Can reduce “random restriction” by focusing experiments on the most plausible candidates.
- Provides a baseline you can compare against after a sustained diet change, if retesting is appropriate.
- Supports a more complete conversation when paired with IgE testing for immediate allergy concerns.
- Makes it easier to track your results and questions over time with PocketMD and your lab history.
What is Broccoli F260 IgG?
Broccoli F260 IgG measures the amount of immunoglobulin G (IgG) antibodies in your blood that bind to broccoli proteins. “F260” is the laboratory code used to identify broccoli as the specific food antigen being tested.
IgG is a common antibody class involved in immune recognition and memory. Because IgG can rise with repeated exposure to a food, a positive or higher result does not automatically mean the food is “harmful” for you. In many people, IgG reflects that you eat the food regularly.
Where this test can be useful is when you treat it as one piece of evidence. If your symptoms reliably improve when broccoli is removed and return when it is reintroduced, an IgG result may support that pattern. If there is no symptom relationship, the number alone is usually not a reason to avoid broccoli.
If you are worried about immediate reactions (minutes to two hours after eating), IgE testing and allergy evaluation are more relevant than IgG.
What do my Broccoli F260 IgG results mean?
Low Broccoli F260 IgG
A low result generally means the lab did not detect meaningful IgG binding to broccoli proteins, or it detected it at a very low level. This often happens if you rarely eat broccoli, if your immune system has not formed a strong IgG response to it, or if your exposure has been minimal recently. A low result does not rule out non-immune food intolerance (such as FODMAP-related symptoms) or reactions driven by preparation methods, portion size, or overall diet pattern.
In-range / typical Broccoli F260 IgG
Many labs report IgG on a scale where “in-range” or “typical” values are common in the general population. In this middle zone, the result is usually interpreted as compatible with routine exposure and not strongly suggestive of a clinically meaningful trigger on its own. If you have symptoms, the next step is usually to look at timing and reproducibility rather than the number alone. A structured elimination-and-rechallenge is often more informative than repeated testing without a plan.
High Broccoli F260 IgG
A higher result means your blood contains more IgG antibodies that bind to broccoli proteins. This can occur because you eat broccoli frequently, because your immune system is more reactive to that antigen, or because your gut/immune environment is primed toward antibody production. A high result does not diagnose a food allergy and does not predict anaphylaxis risk. It is best used as a “priority signal” for a careful trial: remove broccoli for a defined period, then reintroduce it and watch for a consistent symptom pattern.
Factors that influence Broccoli F260 IgG
How often you eat broccoli is one of the biggest drivers of IgG levels, so frequent intake can raise results even when you tolerate the food well. Recent diet changes, pregnancy, immune-modulating medications, and active inflammatory or infectious conditions can also shift antibody patterns. Cross-reactivity can occur when proteins in different foods are similar, which can blur specificity in some people. Finally, different labs use different methods and cutoffs, so you should interpret changes over time using the same lab whenever possible.

Frequently Asked Questions
Is Broccoli F260 IgG a food allergy test?
No. IgG testing is not the same as IgE-based allergy testing. IgE is associated with immediate allergic reactions, while IgG more often reflects exposure and immune recognition. If you have rapid symptoms like hives, swelling, wheezing, or vomiting soon after eating, ask your clinician about IgE testing and allergy evaluation.
Do I need to fast for a Broccoli IgG blood test?
Fasting is usually not required for an IgG food antibody test. If you are getting other labs at the same draw (like lipids or glucose), follow the fasting instructions for those tests.
If my Broccoli F260 IgG is high, should I stop eating broccoli?
Not automatically. A high IgG result can reflect frequent intake and does not prove broccoli is causing symptoms. If you suspect a connection, the most practical approach is a time-limited elimination (often 2–4 weeks) followed by a deliberate reintroduction while tracking symptoms, ideally with clinician guidance.
How long after removing broccoli should I retest IgG?
IgG antibodies can change slowly, and retesting is not always necessary. If you and your clinician decide to retest, it is typically after a sustained period of dietary change (often 8–12+ weeks) and only if the result would change your plan. Using the same lab method improves comparability.
Can I have symptoms from broccoli even if my IgG is low?
Yes. Symptoms can come from non-immune mechanisms such as fermentable carbohydrates, portion size, cooking method, or overall gut sensitivity. A low IgG result mainly suggests there is not a strong IgG antibody signal to broccoli, but it does not rule out intolerance or other causes.
What tests are helpful to run alongside Broccoli IgG?
That depends on your symptoms. If you have immediate reactions, broccoli-specific IgE (or broader allergy testing) is more relevant. If symptoms are delayed and multi-food, a broader IgG food panel may help with prioritization, but it should be paired with a symptom diary and a clear elimination/rechallenge plan.
