Wild Rye G70 IgG
It measures IgG antibodies to wild rye to support symptom tracking and elimination planning, with convenient ordering and results via Vitals Vault/Quest.
This panel bundles multiple biomarker tests in one order—your report explains how results fit together.
A Wild Rye G70 IgG test measures your immune system’s IgG antibodies that bind to proteins from wild rye. People usually order it when they are trying to connect recurring symptoms with specific foods or grains.
IgG results are not the same thing as a classic “allergy test.” They are best used as one piece of evidence to guide a structured trial—such as a time-limited elimination and reintroduction—rather than as a stand-alone diagnosis.
If you already have a result, the most useful next step is to interpret it alongside your symptoms, your diet pattern, and any other relevant tests (especially IgE testing if you have immediate reactions).
Do I need a Wild Rye G70 IgG test?
You might consider Wild Rye G70 IgG testing if you have ongoing, hard-to-pin-down symptoms that seem to fluctuate with what you eat, such as bloating, abdominal discomfort, changes in stool pattern, headaches, skin flares, or “brain fog.” It can also be useful if you notice symptoms after grain-based meals but you are not sure which grain is most associated with your symptoms.
This test can be a reasonable option when you are planning a careful elimination diet and want a short list of foods to prioritize. It is also sometimes used to help you decide what to reintroduce first after a period of dietary simplification.
You may not need this test if you have immediate symptoms like hives, lip/tongue swelling, wheezing, or anaphylaxis after eating grain products. Those patterns fit an IgE-mediated allergy better, and IgE testing plus clinician guidance is the safer path.
No matter what your result shows, it should support clinician-directed care and symptom tracking rather than self-diagnosis. If symptoms are severe, persistent, or associated with weight loss, blood in stool, or anemia, you should seek medical evaluation rather than relying on food antibody testing alone.
This is typically a CLIA-validated laboratory immunoassay; results are for education and clinical context and are not, by themselves, diagnostic of allergy, intolerance, or disease.

Get this test with Vitals Vault
Vitals Vault lets you order Wild Rye G70 IgG testing without needing to coordinate a separate lab requisition visit. After you place your order, you complete your blood draw at a participating lab location, and your results are delivered to your Vitals Vault dashboard.
If you are unsure how to use an IgG result, PocketMD can help you turn it into a practical next step. That usually means reviewing your symptom timeline, identifying the most likely dietary exposures (wild rye can appear in grain blends), and choosing a retest window if you make a meaningful change.
You can also use Vitals Vault to expand beyond a single marker when it makes sense, such as adding related food antibody markers or pairing with IgE testing if you have immediate reactions. The goal is to help you move from “I have a number” to a plan you can discuss with your clinician and track over time.

Key benefits of Wild Rye G70 IgG testing
- Helps you evaluate whether wild rye exposure is worth prioritizing in an elimination and reintroduction plan.
- Adds objective context when symptoms seem delayed or inconsistent after grain-based meals.
- Can narrow the focus of broader “food sensitivity” questions so you are not changing too many foods at once.
- Supports retesting after a sustained dietary change to see whether antibody levels trend down over time.
- May help you distinguish grain-specific patterns from more general triggers like high FODMAP meals or alcohol.
- Pairs well with symptom tracking and other labs (such as IgE testing) to separate immediate allergy patterns from delayed reactions.
- Gives you a standardized lab result you can review in PocketMD and share with your clinician for next-step planning.
What is Wild Rye G70 IgG?
Wild Rye G70 IgG is a blood test that measures immunoglobulin G (IgG) antibodies directed at proteins from wild rye. In simple terms, it looks for evidence that your immune system has “seen” wild rye proteins and produced IgG that can bind to them.
IgG antibodies are common in the body and often reflect exposure rather than disease. For some people, higher food-specific IgG levels may correlate with symptoms, but the relationship is not straightforward. That is why this test is most useful when you interpret it alongside your history and then test a hypothesis with a structured diet trial.
Wild rye can be present in certain grain mixes, specialty flours, or products labeled with mixed grains. If you eat a lot of grain-based foods, your immune system may produce measurable IgG even if you do not have symptoms.
IgG vs IgE: why the distinction matters
IgE is the antibody type most associated with immediate allergic reactions (minutes to a few hours), such as hives, swelling, wheezing, or anaphylaxis. IgG is not the classic driver of those emergency-type reactions. If your concern is an immediate reaction, IgE testing and clinician guidance are more appropriate than relying on IgG.
What this test can and can’t answer
This test can help you decide whether wild rye is a reasonable food to trial out of your diet for a defined period, especially when symptoms are delayed or hard to link to a single meal. It cannot prove that wild rye is the cause of your symptoms, and it does not diagnose celiac disease, wheat allergy, or inflammatory bowel disease.
What do my Wild Rye G70 IgG results mean?
Low Wild Rye G70 IgG
A low result generally means your blood shows little to no IgG binding to wild rye proteins at the time of testing. This often happens when you rarely eat wild rye, when your exposure is minimal, or when wild rye is unlikely to be a meaningful trigger for you. If you still have symptoms after grain-based meals, you and your clinician may look at other grains, non-grain triggers, or a different mechanism such as IgE-mediated allergy or non-immune food intolerance.
In-range (or borderline) Wild Rye G70 IgG
A mid-range or borderline result is common and can simply reflect routine dietary exposure. On its own, it does not confirm that wild rye is causing symptoms. If your symptoms and food log strongly point to rye-containing foods, a short, structured elimination followed by a careful reintroduction is usually more informative than reacting to a borderline number.
High Wild Rye G70 IgG
A high result means you have a stronger IgG antibody signal to wild rye proteins. This can occur with frequent exposure, increased immune recognition, or sometimes in people who report symptoms that improve when the food is removed. The most practical way to use a high result is to treat it as a hypothesis: remove wild rye sources for a defined period, track symptoms, and then reintroduce to see whether symptoms reproducibly return.
Factors that influence Wild Rye G70 IgG
Your usual diet is a major driver—more exposure can lead to higher IgG levels even without symptoms. Timing matters too: if you recently avoided rye, your level may be lower than it would be during regular intake. Immune system variability, gut inflammation, and cross-reactivity among related grains can also affect results. Finally, different labs and methods may use different reporting scales, so it helps to interpret your number using the reference information on your report and to trend results at the same lab when retesting.

Frequently Asked Questions
Is Wild Rye G70 IgG the same as a rye allergy test?
No. An allergy test usually refers to IgE testing, which is designed to evaluate immediate-type allergic reactions. Wild Rye G70 IgG measures IgG antibodies, which are more often used to support symptom tracking and elimination/reintroduction planning rather than diagnosing allergy.
Do I need to fast for a Wild Rye IgG blood test?
Fasting is not typically required for an IgG food antibody test. If you are combining it with other labs (like lipids or glucose/insulin), follow the fasting instructions for the full set of tests you ordered.
If my Wild Rye IgG is high, should I stop eating rye forever?
Not automatically. A high IgG result is best treated as a signal to test a structured plan: remove wild rye sources for a defined period, track symptoms, and then reintroduce to see whether symptoms reliably return. Long-term restriction is usually a decision you make based on reproducible symptom response and clinician guidance.
How long should I eliminate wild rye before retesting?
Many people trial an elimination for several weeks, then decide whether retesting is useful based on symptom change and how strict the avoidance was. If you retest, it is most meaningful when your diet has been stable for a sustained period and you use the same lab method so results are comparable.
Can a low Wild Rye IgG result rule out food sensitivity?
No. A low result suggests low measurable IgG binding to wild rye proteins at the time of testing, but symptoms can still come from other foods, other grains, non-immune intolerances, or conditions unrelated to diet. If symptoms persist, it can help to review a broader differential with your clinician.
What foods might contain wild rye?
Wild rye may appear in mixed-grain products, specialty flours, or grain blends where rye is one component. Labels are not always specific about “wild rye” versus other rye varieties, so if you are doing an elimination, you may need to avoid rye-containing products broadly and track what you actually eat.
