Broccoli F260 IgE
It measures IgE antibodies to broccoli to assess allergy sensitization, with convenient ordering and Quest-based lab collection through Vitals Vault.
This panel bundles multiple biomarker tests in one order—your report explains how results fit together.

A Broccoli F260 IgE test is a blood test that looks for allergy-type antibodies (IgE) your immune system may make in response to broccoli.
This test does not diagnose an allergy by itself. Instead, it helps answer a narrower question: are you sensitized to broccoli in a way that could fit with immediate-type allergy symptoms, especially when the story and timing match.
If you are trying to sort out whether a reaction is “allergy” versus “intolerance,” or you are comparing food triggers, this result can be useful when you interpret it alongside your symptoms and any other allergy testing your clinician recommends.
Do I need a Broccoli F260 IgE test?
You may consider Broccoli F260 IgE testing if you get symptoms soon after eating broccoli (often within minutes to 2 hours). That can include hives, itching, lip or tongue swelling, throat tightness, wheezing, coughing, vomiting, or sudden abdominal cramping. The key clue is timing: IgE-mediated reactions tend to be rapid and reproducible with exposure.
This test can also help if you have pollen allergies and notice mouth or throat itching with certain raw fruits or vegetables. Some people react due to cross-reactivity (your immune system recognizes similar proteins), and a broccoli-specific IgE result can be one piece of that puzzle.
You might not need this test if your symptoms are delayed (many hours later), primarily digestive and chronic, or inconsistent. Those patterns are more often related to non-IgE mechanisms, food intolerance, reflux, infections, or other GI conditions.
Testing is most helpful when it supports clinician-directed care, such as deciding whether you need an allergist evaluation, an oral food challenge, an emergency action plan, or a targeted elimination and reintroduction strategy.
This is typically a CLIA-validated laboratory immunoassay for allergen-specific IgE; results support clinical decision-making but are not a standalone diagnosis of food allergy.

After you order, you complete your blood draw at a participating lab location. When results are ready, you can use PocketMD to get plain-language context, questions to ask at your next visit, and ideas for sensible follow-up testing based on your history.
If your result is positive or confusing, you can also use Vitals Vault to add companion allergy tests (such as related food IgE or pollen IgE) so you are not guessing from a single number.
- Order online and complete a standard blood draw at a local lab location
- PocketMD helps you interpret results and plan next steps
- Easy re-testing if you and your clinician want to track changes over time
Key benefits of Broccoli F260 IgE testing
- Helps identify IgE sensitization to broccoli when your symptoms happen soon after eating it.
- Supports safer decision-making about avoidance, reintroduction, and when to seek allergist input.
- Can clarify whether “broccoli intolerance” symptoms fit an immediate allergy pattern or not.
- Helps interpret possible cross-reactivity in people with pollen allergies and oral itching with raw produce.
- Provides an objective baseline you can compare with future results if your exposure or symptoms change.
- Guides smarter follow-up testing (additional food IgE, pollen IgE, or component testing when appropriate).
- Pairs well with PocketMD so you can translate the lab number into practical next steps and questions for your clinician.
What is Broccoli F260 IgE?
Broccoli F260 IgE is a “specific IgE” blood test. It measures the amount of immunoglobulin E (IgE) antibodies in your blood that bind to broccoli proteins.
IgE is the antibody class involved in classic immediate-type allergic reactions. If you are sensitized, your immune system has made IgE that recognizes broccoli. When you eat broccoli, that recognition can trigger immune cells (mast cells and basophils) to release chemicals like histamine, which can cause hives, swelling, wheezing, vomiting, or other rapid symptoms.
A positive result means sensitization, not automatically a clinical allergy. Some people have detectable IgE but tolerate the food, while others react strongly with only modest IgE levels. Your symptom history, timing, amount eaten, and other allergy conditions determine how meaningful the number is.
This test is different from IgG food testing. IgG often reflects exposure or immune recognition and is not considered diagnostic for food allergy. If you are trying to evaluate immediate reactions, IgE is the more relevant antibody class.
What do my Broccoli F260 IgE results mean?
Low or undetectable Broccoli IgE
A low (or negative) result suggests you are not sensitized to broccoli in an IgE-mediated way. That makes an immediate-type broccoli allergy less likely, but it does not fully rule it out, especially if your reaction was severe or the test was done long after avoiding the food. If you still have convincing symptoms, your clinician may consider skin testing, repeat testing, or a supervised oral food challenge.
In-range result (often reported as negative)
For specific IgE tests, “optimal” usually means the lab did not detect clinically meaningful broccoli-specific IgE. If your symptoms are delayed, mainly digestive, or inconsistent, this pattern may point away from IgE allergy and toward other causes such as intolerance, reflux, irritable bowel patterns, or reactions to preparation methods. Your next step is usually to match the lab result to your symptom timeline rather than making broad dietary changes.
Elevated Broccoli IgE
An elevated result indicates sensitization to broccoli. The higher the value, the more likely it is that broccoli could be clinically relevant, but the number alone cannot predict reaction severity. If you have had rapid symptoms after eating broccoli, a positive test strengthens the case for an IgE-mediated allergy and is a reason to discuss an allergist referral, risk assessment, and whether you need an emergency plan.
Factors that influence Broccoli F260 IgE
Your overall “atopic” tendency matters: people with eczema, asthma, or multiple allergies can have higher IgE reactivity and more false positives. Cross-reactivity can also affect results, especially if you have pollen allergies and react to related plant proteins. Recent exposure patterns may influence interpretation, because long-term avoidance can sometimes reduce measurable IgE over time. Finally, lab methods and reporting thresholds vary, so it helps to compare results from the same lab when trending.

Frequently Asked Questions
What does the Broccoli F260 IgE test measure?
It measures broccoli-specific IgE antibodies in your blood. These antibodies are associated with immediate-type allergic reactions, but a positive result indicates sensitization and must be interpreted with your symptoms and history.
Do I need to fast for a broccoli IgE blood test?
Fasting is usually not required for specific IgE testing. If you are combining this test with other labs (like lipids or glucose), follow the fasting instructions for the full set of tests you ordered.
Can a positive broccoli IgE mean I will have anaphylaxis?
No. The test cannot predict reaction severity on its own. Anaphylaxis risk depends on your prior reactions, asthma control, co-factors (exercise, alcohol, illness), and clinical evaluation, not just the IgE number.
Can I have broccoli allergy symptoms with a negative IgE test?
Yes. A negative test makes IgE-mediated allergy less likely, but it does not rule out non-IgE reactions, intolerance, or other causes of symptoms. In some cases, additional testing or a supervised oral food challenge is needed to clarify what is happening.
Is broccoli IgE the same as broccoli IgG?
No. IgE is tied to immediate allergy-type reactions. IgG to foods more often reflects exposure and is not considered diagnostic for food allergy. If your concern is rapid symptoms after eating broccoli, IgE is the more relevant test.
How long after a reaction should I test?
You can usually test at any time because this measures baseline sensitization rather than an acute surge. If you have avoided broccoli for a long time, talk with your clinician about whether repeat testing or other methods (like skin testing) would better match your situation.
What follow-up tests are commonly paired with Broccoli F260 IgE?
Common next steps include other specific IgE food tests based on your diet history, pollen IgE testing if oral itching is a pattern, and sometimes broader allergy panels. If GI symptoms dominate, your clinician may also consider non-allergy evaluations (for example, celiac-related testing) depending on your symptoms.
