It measures IgE sensitization to Bermuda grass pollen to support allergy evaluation, with convenient ordering and Quest lab collection via Vitals Vault.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
Bermuda Grass G2 IgE is a blood test that looks for allergy antibodies (IgE) that react to Bermuda grass pollen. It helps answer a specific question: are you sensitized to Bermuda grass in a way that could match your symptoms and exposure?
A positive result does not automatically mean Bermuda grass is the reason you feel miserable outside, and a negative result does not rule out every grass-related problem. Your timing (season), where you live, and what happens when you are exposed matter just as much as the number on the page.
This test is most useful when you connect it to a real pattern—like itchy eyes and sneezing during warm months, symptoms after mowing, or flares that track with local pollen counts—and when you interpret it alongside other allergy testing and your clinical history.
Do I need a Bermuda Grass G2 IgE test?
You might consider Bermuda Grass (G2) IgE testing if you get seasonal allergy symptoms—sneezing, congestion, itchy/watery eyes, post-nasal drip, cough, or asthma flares—that seem worse in late spring through fall, especially in warm climates where Bermuda grass is common.
It can also be helpful if your symptoms spike with outdoor exposure (yard work, sports fields, parks) or if you are trying to separate “grass pollen” from other common triggers like tree pollen, weeds, dust mites, or mold. If you already know you react to “grass” on a broad screening test, a Bermuda-specific result can help narrow which grasses are most relevant.
You may also want this test if you have a positive allergy test but you are not sure it matches your day-to-day experience. IgE tests measure sensitization, which can exist without noticeable symptoms, so the goal is to interpret your result against your actual exposures.
This information is meant to support clinician-directed care and shared decision-making, not to diagnose an allergy on its own.
This is an allergen-specific IgE blood test performed in a CLIA-certified laboratory; results should be interpreted with your symptoms and exposure history rather than used as a standalone diagnosis.

Get this test with Vitals Vault
With Vitals Vault, you can order Bermuda Grass (G2) IgE testing directly and complete your blood draw at a participating Quest collection site. That can be useful when you are trying to clarify a seasonal pattern, confirm a suspected trigger, or decide whether broader aeroallergen testing makes sense.
Once your result is back, PocketMD can help you translate it into next steps that fit your situation—such as whether to add other grass or weed pollens, check for cross-reactive patterns, or focus on exposure control and symptom tracking during peak season.
If your history suggests multiple environmental triggers, you can use your Bermuda result as a starting point and expand to a broader allergy panel so you are not guessing based on one data point.
- Order online and use a nationwide Quest draw site
- PocketMD helps you interpret results in context of symptoms and season
- Easy to retest to track changes over time when clinically appropriate
Key benefits of Bermuda Grass (G2) IgE testing
- Helps confirm whether Bermuda grass pollen sensitization fits your seasonal or outdoor-triggered symptoms.
- Distinguishes “sensitized” from “likely clinically relevant” when paired with your exposure history.
- Supports more targeted environmental control (for example, mowing precautions and timing outdoor activity).
- Helps guide whether you should broaden testing to other grasses, weeds, molds, or indoor allergens.
- Provides an objective data point when symptoms overlap with colds, nonallergic rhinitis, or irritant exposure.
- Can help explain asthma or cough flares that track with warm-season pollen peaks.
- Creates a baseline you can revisit with PocketMD when symptoms change or when you retest.
What is Bermuda Grass (G2) IgE?
Bermuda Grass (G2) IgE is a lab measurement of immunoglobulin E (IgE) antibodies in your blood that recognize proteins from Bermuda grass pollen (Cynodon dactylon). IgE is the antibody type involved in immediate-type allergy reactions, where exposure can trigger histamine release and symptoms like sneezing, itching, watery eyes, wheezing, or hives.
A key point is that the test measures sensitization, not severity. Sensitization means your immune system has made IgE that can bind to Bermuda grass allergens. Whether that sensitization causes symptoms depends on dose and timing of exposure, your nasal and airway sensitivity, other allergies, and factors like infections or irritants.
Bermuda grass is more common in warmer regions and can pollinate over a long season. If your symptoms are mainly in warm months, occur after being on lawns or sports fields, or worsen with mowing, Bermuda grass IgE may be a relevant piece of your allergy picture.
Blood IgE vs skin testing
Skin prick testing and blood IgE testing often agree, but they are not identical. Skin tests reflect reactivity in the skin at that moment, while blood IgE reflects circulating antibodies. Medications, skin conditions, and timing can affect skin testing, while blood IgE can be helpful when skin testing is not practical or when you want a specific numeric result to trend.
Why “G2” matters
“G2” is the laboratory code used for Bermuda grass in many allergen-specific IgE systems. It helps ensure you and your clinician are talking about the same allergen source rather than a generic “grass mix.”
What do my Bermuda Grass (G2) IgE results mean?
Low or undetectable Bermuda grass IgE
A low or undetectable result suggests you are not sensitized to Bermuda grass pollen, or that your IgE level is below the assay’s detection threshold. If you still have strong seasonal symptoms, other grasses, weeds, trees, molds, or indoor allergens may be more relevant. Nonallergic rhinitis (irritant-triggered congestion) can also mimic pollen allergy, especially with smoke, fragrances, or temperature changes.
In-range results (interpretation depends on the lab’s reference and class)
Allergen-specific IgE is often reported as a numeric value and sometimes grouped into “classes.” There is not a single universal “optimal” number the way there is for cholesterol; instead, the question is whether the result aligns with your symptom pattern and exposure. A borderline or low-positive result can be meaningful if you reliably flare during Bermuda grass season, and it can be incidental if you have no symptoms when exposed.
High Bermuda grass IgE
A higher result increases the likelihood that Bermuda grass sensitization is clinically relevant, especially if your symptoms track with warm-season pollen and outdoor exposure. However, the number alone does not predict how severe your symptoms will be, and it does not prove Bermuda grass is the only trigger. Many people with high grass IgE also react to other pollens, so broader testing and a careful history can prevent false reassurance or overly narrow conclusions.
Factors that influence Bermuda grass IgE
Your result can be influenced by where you live, the length and intensity of the local pollen season, and how much time you spend outdoors. Other atopic conditions (eczema, asthma, allergic rhinitis) and higher total IgE can make positive results more likely. Cross-reactivity between different grasses can also contribute, meaning your immune system may recognize similar proteins across multiple grass pollens. Recent infections, uncontrolled nasal inflammation, and ongoing high exposure can make symptoms worse even if the IgE number does not change much.

Frequently Asked Questions
What does a Bermuda grass (G2) IgE test measure?
It measures the amount of IgE antibodies in your blood that recognize Bermuda grass pollen. This indicates sensitization, which may or may not match real-world allergy symptoms.
Do I need to fast for a Bermuda grass IgE blood test?
Fasting is not typically required for allergen-specific IgE testing. If you are getting other labs at the same time, follow the instructions for the full set of tests you ordered.
Can a positive Bermuda grass IgE mean I’m allergic even if I feel fine?
Yes. You can be sensitized (positive IgE) without noticeable symptoms, especially if your exposure is low or your symptoms are mild. The result becomes more meaningful when it lines up with symptoms during Bermuda grass pollen season or after specific exposures like mowing.
What is considered a “high” Bermuda grass IgE level?
Labs often report allergen-specific IgE as a number and sometimes as a class (for example, low, moderate, high). Because cutoffs and reporting vary by lab method, “high” is best defined by the reference scale on your report and whether the result fits your clinical pattern.
Is blood IgE testing as accurate as skin prick testing for grass allergy?
They are complementary. Blood IgE testing is useful when you want a specific allergen result and a number you can trend, or when skin testing is not practical. Skin testing can be very informative as well, and your clinician may use both depending on your history and medications.
Could Bermuda grass IgE be related to pollen-food syndrome?
Sometimes. Pollen-food syndrome (oral allergy syndrome) is usually linked to cross-reactive proteins found in pollens and certain raw fruits or vegetables. If you have mouth or throat itching with specific foods during pollen season, broader pollen testing and evaluation of cross-reactive components can help clarify the pattern.
If my Bermuda grass IgE is negative, what should I test next?
If symptoms persist, consider broader aeroallergen testing that includes other grasses, weeds, trees, molds, and indoor allergens like dust mites and pet dander. PocketMD can help you map your symptoms and seasonality to a sensible next testing step.
