Wild Rye Grass G70 IgE (Wild Rye Grass Allergy) Biomarker Testing
It measures IgE antibodies to wild rye grass to help assess allergy sensitization, with easy ordering and Quest lab draw access via Vitals Vault.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
A Wild Rye Grass G70 IgE test looks for allergy-type antibodies (IgE) your immune system may make after becoming sensitized to wild rye grass pollen.
This is a blood test that can support the workup of seasonal allergy symptoms such as sneezing, itchy eyes, congestion, post-nasal drip, or cough that tends to flare during grass pollen season.
Your result does not diagnose an allergy by itself. It is most useful when you interpret it alongside your symptoms, timing of exposure, and other allergy testing your clinician may recommend.
Do I need a Wild Rye Grass G70 IgE test?
You might consider Wild Rye Grass G70 IgE testing if your symptoms reliably worsen during late spring or summer, if you notice flares after outdoor activities (yard work, hiking, sports fields), or if you have ongoing “hay fever” symptoms that do not clearly respond to first-line measures.
This test can also be helpful if you have asthma that worsens seasonally, recurrent sinus symptoms that seem tied to pollen season, or eczema that flares with outdoor exposure. If you are trying to reduce triggers, a specific IgE result can help you decide whether grass pollen avoidance steps are likely to matter for you.
You may also want this test if skin-prick testing is not practical (for example, you cannot stop antihistamines, you have extensive eczema, or you prefer a blood draw). Testing is especially useful when you and your clinician are deciding whether broader grass pollen testing, additional environmental allergens, or allergy immunotherapy should be part of your plan.
If you have had severe reactions, trouble breathing, or symptoms of anaphylaxis, seek urgent care. Lab testing supports clinician-directed care and does not replace medical evaluation.
This is a CLIA-certified laboratory blood test for allergen-specific IgE; results indicate sensitization and should be interpreted with your symptoms and clinical history, not as a standalone diagnosis.

Get this test with Vitals Vault
Vitals Vault makes it straightforward to order Wild Rye Grass G70 IgE testing when you want clearer answers about seasonal symptoms. You can order online and complete your blood draw at a participating Quest location.
Once your results are in, PocketMD can help you translate the number into plain language: what “sensitization” means, how strong the signal is, and what follow-up questions to bring to your clinician. If your symptoms suggest more than one trigger, you can also use your results to decide whether adding other specific IgE tests or a broader allergy panel makes sense.
If you are tracking patterns over time—such as before and after starting allergy medications, changing your environment, or considering immunotherapy—Vitals Vault also supports retesting so you can compare results in a consistent way.
- Order online and draw at a Quest location
- Clear, shareable results you can review with your clinician

Key benefits of Wild Rye Grass G70 IgE testing
- Helps identify whether wild rye grass pollen is a likely trigger for your seasonal allergy symptoms.
- Supports a targeted avoidance plan (timing outdoor activities, indoor air strategies) instead of guessing.
- Clarifies whether “hay fever” symptoms may be allergic when infections or irritants are also possible.
- Guides whether you should expand testing to other grasses, weeds, trees, or indoor allergens.
- Adds objective data to asthma or chronic cough evaluations when symptoms worsen during pollen season.
- Helps you and your clinician decide if allergy immunotherapy is worth discussing for grass pollen sensitization.
- Makes it easier to track and interpret results over time with PocketMD and consistent lab ordering.
What is Wild Rye Grass G70 IgE?
Wild Rye Grass G70 IgE is a blood test that measures the amount of immunoglobulin E (IgE) antibodies in your blood that bind to wild rye grass allergen extracts. IgE is the antibody class involved in immediate-type allergic reactions, including allergic rhinitis (hay fever) and some asthma flares.
A positive (elevated) specific IgE result suggests your immune system has become sensitized to wild rye grass pollen. Sensitization means your body recognizes the allergen and has made IgE against it, but it does not prove that exposure is the cause of your symptoms. The most useful interpretation comes from matching your result to real-world timing: when grass pollen is high, whether symptoms occur after outdoor exposure, and whether symptoms improve with allergy-directed treatment.
Because many grass pollens share similar proteins, cross-reactivity can occur. That means IgE may bind to multiple grass species even if you have not identified a single specific grass as the trigger. Your clinician may use this test as one piece of a broader environmental allergy assessment.
What do my Wild Rye Grass G70 IgE results mean?
Low Wild Rye Grass G70 IgE (negative or very low sensitization)
A low result generally means wild rye grass is less likely to be a major driver of your symptoms. If you still have strong seasonal symptoms, other allergens (other grasses, trees, weeds, molds) or non-allergic causes (irritants, viral illness, reflux) may be more relevant. Timing matters: if your symptoms peak outside of grass pollen season, a low result fits that pattern. If suspicion remains high, your clinician may recommend broader testing or skin testing.
In-range Wild Rye Grass G70 IgE (interpret within your lab’s reference categories)
For specific IgE tests, “in range” usually means below the lab’s positivity cutoff. That is often interpreted similarly to a low/negative result, but it does not completely rule out allergy in every person. If your symptoms are classic and tightly linked to outdoor exposure, your clinician may still consider other grasses, cross-reactive pollens, or repeating testing as part of a broader plan. The best next step is usually to compare your symptom calendar to local pollen patterns.
High Wild Rye Grass G70 IgE (sensitization more likely)
A high result suggests you are sensitized to wild rye grass pollen and that exposure could be contributing to symptoms such as sneezing, itchy/watery eyes, congestion, or asthma flares during grass season. Higher values can correlate with a higher likelihood of clinical reactivity, but the number alone does not predict how severe your symptoms will be. If your symptoms line up with grass pollen season, this result can support targeted avoidance steps and a discussion about medication timing or immunotherapy. If symptoms do not match exposure, cross-reactivity or another trigger may explain the finding.
Factors that influence Wild Rye Grass G70 IgE
Your overall allergic tendency (atopy), including eczema, allergic rhinitis, or asthma, can increase the likelihood of positive specific IgE results. Cross-reactivity among grasses can raise results even when you cannot pinpoint one grass species, and co-sensitization to other pollens is common. Recent exposure does not usually cause rapid day-to-day swings in IgE the way some other markers fluctuate, but results can change over longer periods, especially in children or with immunotherapy. Lab methods and reporting categories vary, so compare results using the same lab when possible and interpret them with your clinician.

Frequently Asked Questions
What does the Wild Rye Grass G70 IgE test measure?
It measures allergen-specific IgE antibodies in your blood that bind to wild rye grass pollen. This helps assess whether you are sensitized to that allergen, which can support an allergy evaluation when symptoms and exposure timing fit.
Does a positive G70 IgE mean I am definitely allergic to wild rye grass?
Not necessarily. A positive result indicates sensitization, but true allergy depends on whether exposure triggers symptoms. Your clinician typically interprets the result alongside your history, seasonality, and sometimes additional testing.
Do I need to fast before an allergen-specific IgE blood test?
Fasting is not usually required for specific IgE testing. If you are getting other labs at the same visit, follow the instructions for the full set of tests you ordered.
Can antihistamines affect my Wild Rye Grass IgE blood test result?
Antihistamines can interfere with skin-prick testing, but they generally do not change allergen-specific IgE blood test results in a meaningful way. If you are on immune-modifying medications or biologics for asthma/allergy, ask your clinician how to interpret results in your situation.
What is a normal range for Wild Rye Grass G70 IgE?
Labs typically report specific IgE as negative/below a cutoff or in classes (for example, class 0 to class 6) based on the measured value. Because cutoffs and reporting can vary by lab method, use the reference information shown on your report and interpret it with your symptoms.
When should I retest Wild Rye Grass IgE?
Retesting is usually considered when your clinical situation changes—such as new or worsening seasonal symptoms, starting or completing allergy immunotherapy, or when you are expanding your allergy workup. For many people, repeating within weeks is not helpful; changes are more meaningful over months to years.
Should I test for other grasses if this is positive?
Often, yes. Grass pollens can cross-react, and many people are sensitized to multiple grasses. If your symptoms are seasonal, your clinician may recommend a broader grass mix, additional specific grasses, or a more complete environmental allergy panel to map triggers.
