Allergen Specific IgG Bean Navy White (Navy/White Bean) — IgG Food Antibody Biomarker Testing
It measures IgG antibodies to navy/white bean proteins to support food-reaction context, with Vitals Vault ordering and Quest-based lab access.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
This test looks for IgG antibodies your immune system has made against proteins found in navy beans and white beans. Your report is usually presented as a numeric value with a lab-specific reference range or “class” category.
People often consider this test when they are trying to connect recurring symptoms with foods, especially when reactions feel delayed or inconsistent. It can be tempting to treat any positive IgG result as a diagnosis, but IgG is best used as one piece of a bigger picture rather than a stand-alone answer.
If you already have a result, the most helpful next step is to interpret it alongside your symptoms, your usual intake of beans/legumes, and—when appropriate—IgE allergy testing and other clinical history.
Do I need a Allergen Specific IgG Bean Navy White test?
You might consider navy/white bean IgG testing if you notice repeatable symptoms that you suspect are food-related, but the timing is not immediate. Examples include bloating, abdominal discomfort, changes in stool pattern, headaches, skin flares, or fatigue that seem to show up hours to a day after meals.
This test can also be reasonable if you are already doing a structured elimination-and-rechallenge plan and you want an additional data point to decide which foods to trial first. It is most useful when you can pair the result with a clear symptom log and a realistic plan to confirm (or rule out) a relationship.
You may not need this test if you have signs of a classic immediate allergy—such as hives, swelling, wheezing, throat tightness, or vomiting soon after eating beans. In that situation, IgE-based allergy evaluation and clinician guidance are the priority.
Testing can support clinician-directed care and a more organized trial of dietary changes, but it does not diagnose food allergy or automatically prove that a food is “bad” for you.
This is typically a CLIA-validated laboratory immunoassay; results are not a stand-alone diagnosis and should be interpreted in clinical context.

Get this test with Vitals Vault
With Vitals Vault, you can order allergen-specific IgG testing without needing to coordinate a separate lab requisition visit first. After you place your order, you’ll complete your blood draw through a national lab network and then review results in your Vitals Vault dashboard.
Because food IgG results can be confusing, you can use PocketMD to talk through what your number may mean for you, what to track, and how to plan a careful elimination-and-rechallenge rather than making sweeping diet changes based on a single data point.
If your goal is a broader map of possible triggers, you can also add related allergen markers or panels and trend results over time when retesting makes sense (for example, after a sustained change in exposure or symptoms).
- Order online and complete a local blood draw through a national lab network
- PocketMD support to help you interpret results and plan next steps
- Easy reordering when you want to retest after a structured trial
Key benefits of Allergen Specific IgG Bean Navy White testing
- Gives you a measurable signal of immune recognition (IgG) to navy/white bean proteins.
- Helps you prioritize which foods to trial first when you are planning an elimination-and-rechallenge.
- Adds context when symptoms feel delayed and you are struggling to identify patterns from diet alone.
- Can reduce guesswork by pairing a lab value with a symptom log and exposure history.
- Supports more targeted conversations with your clinician about food reactions versus true allergy.
- Helps you decide when IgE allergy testing or other evaluations may be more appropriate.
- Makes it easier to track changes over time if you retest after changing intake or symptoms.
What is Allergen Specific IgG Bean Navy White?
Allergen-specific IgG is a blood test that measures IgG antibodies directed at a particular food protein—in this case, proteins found in navy beans and white beans (both common beans in the legume family). IgG antibodies are part of your adaptive immune system and often reflect exposure and immune “memory.”
Unlike IgE (immunoglobulin E), which is the antibody class most associated with immediate-type allergic reactions, IgG is not a reliable marker of classic food allergy. Many people develop IgG antibodies to foods they eat regularly without having any symptoms.
For that reason, an IgG result is best treated as a clue to investigate, not a verdict. The practical value comes from combining the result with your symptom timing, how often you eat beans/legumes, and whether symptoms improve and return with a controlled elimination and reintroduction.
IgG vs IgE: why the distinction matters
If you are worried about an immediate allergic reaction, IgE testing (and clinician evaluation) is the more appropriate pathway. IgG testing is sometimes used in the context of suspected delayed or non-IgE-mediated reactions, but it cannot confirm intolerance on its own.
Why beans can be a common “suspect” food
Beans contain multiple proteins and fermentable carbohydrates that can trigger symptoms for different reasons. Some people react to the food itself, while others react to portion size, preparation, or gut sensitivity (for example, gas and bloating from fermentation). An IgG result does not separate these causes, but it can help you decide what to test first in a structured way.
What do my Allergen Specific IgG Bean Navy White results mean?
Low or negative IgG to navy/white bean
A low (or “negative”) result means the lab did not detect a meaningful level of IgG antibodies to navy/white bean proteins at the time of testing. This makes an IgG-associated response less likely, but it does not rule out symptoms from other mechanisms, such as carbohydrate fermentation, food additives, or unrelated GI conditions. If beans still seem to trigger symptoms, your next step is usually a careful symptom diary and a short elimination-and-rechallenge rather than assuming the test is definitive.
In-range or borderline IgG to navy/white bean
A mid-range or borderline result often reflects exposure without clear clinical significance. If you eat beans regularly, mild IgG reactivity can simply indicate immune recognition of a common food. In this range, your symptoms and timing matter more than the number itself, and a structured trial is the best way to learn whether beans are truly contributing.
High IgG to navy/white bean
A high result indicates stronger IgG reactivity to navy/white bean proteins compared with the lab’s reference method. This can happen in people who eat beans frequently, and it can also be seen in people who suspect symptoms after eating them. A high value is not proof of allergy, but it can justify a more deliberate elimination-and-rechallenge plan, ideally with clear rules (duration, portion on reintroduction, and what symptoms you will track). If you have any immediate-type reactions, prioritize IgE evaluation regardless of IgG level.
Factors that influence IgG food antibody results
Your usual intake matters: frequent exposure can raise IgG even when you feel fine, while long avoidance can lower IgG even if you are sensitive. Timing can also matter, since antibody levels can shift over weeks to months rather than day to day. Different labs and methods may report results in different units or “classes,” so it is best to compare your results only within the same lab method when trending. Immune conditions and overall inflammation can sometimes affect antibody patterns, which is another reason to interpret results with your broader health context.

Frequently Asked Questions
Is an IgG food test the same as a food allergy test?
No. Classic food allergy is typically IgE-mediated and can cause immediate symptoms like hives, swelling, wheezing, or anaphylaxis. IgG testing measures a different antibody class and cannot diagnose food allergy. If you have immediate reactions, talk with a clinician about IgE testing and an allergy evaluation.
Do I need to fast for an allergen-specific IgG blood test?
Fasting is usually not required for IgG food antibody testing. If you are having other labs drawn at the same visit (like lipids or glucose/insulin), follow the fasting instructions for those tests.
If my navy/white bean IgG is high, should I stop eating beans?
A high IgG result is a reason to be more structured, not necessarily more restrictive. If you want to test whether beans affect you, use a time-limited elimination (often 2–4 weeks) followed by a planned reintroduction while tracking symptoms. Avoid long-term restriction unless you have a clear, repeatable reaction or clinician guidance.
Can I have symptoms from beans even if my IgG is negative?
Yes. Beans can cause symptoms for reasons unrelated to IgG, including fermentable carbohydrates that increase gas and bloating, portion size, preparation methods, or underlying gut sensitivity. A negative IgG result does not rule out these mechanisms.
How soon should I retest allergen-specific IgG?
Because IgG levels tend to change over weeks to months, retesting is usually considered after a sustained change in exposure or symptoms—often 8–12 weeks or longer. If you are using the test to track a dietary trial, keep the lab method consistent so results are comparable.
What foods are related to navy/white beans if I’m troubleshooting reactions?
Navy and white beans are legumes. Some people who react to one legume also notice issues with others (such as kidney beans, black beans, chickpeas, lentils, or peanuts), but cross-reactivity is not guaranteed. Your symptom history and controlled reintroductions are more informative than assuming all legumes are a problem.
