What Is a Bermuda Grass Allergy Test?
The Bermuda grass allergy test is a blood test that measures the level of specific IgE (immunoglobulin E) antibodies your immune system produces in response to Bermuda grass pollen. Doctors typically order it when a patient reports repeated sneezing, nasal congestion, or eye irritation that may be linked to grass pollen exposure. A blood sample from a vein in your arm is all that is needed. The test is also referred to as the allergen G2 test or Cynodon dactylon allergy test.
What Does a Bermuda Grass Allergy Test Measure?
This test measures the concentration of IgE antibodies in your blood that are directed specifically at Bermuda grass pollen proteins. When your immune system is sensitised to this pollen, it produces these antibodies, which can be detected and measured in the lab using a method called fluorescent enzyme immunoassay (FEIA). The higher the antibody level, the greater the degree of sensitisation.
The test reports a single parameter:
| Parameter | What It Indicates |
|---|---|
| Specific IgE to Bermuda grass (g2) | The level of immune sensitisation to Bermuda grass pollen, reported in kU/L across Classes 0 to 6 |
Why Is a Bermuda Grass Allergy Test Done?
A grass pollen allergy test (Bermuda) helps a doctor confirm whether Bermuda grass pollen is responsible for your symptoms. It can also guide decisions about further allergy management, including whether allergen immunotherapy is appropriate.
Common Symptoms That May Require This Test
The following symptoms are among the most common reasons a doctor may recommend this test:
- Frequent sneezing, especially outdoors or during certain seasons
- Blocked or runny nose
- Itchy, watery, or red eyes
- Itchy throat or the roof of the mouth
- Persistent cough
- Asthma flare-ups or wheezing
- General nasal discomfort that does not respond to routine treatment
Conditions This Test Can Help Detect
This test can help identify sensitisation linked to several allergic conditions:
- Allergic rhinitis (commonly called hay fever) affects the nose, eyes, and throat
- Allergic asthma triggered or worsened by grass pollen
- Suspected cross-reactivity with other grass pollens, including Timothy, Kentucky Blue, Johnson, Rye, and Bahia grasses
- Sensitisation that needs to be confirmed before starting allergen immunotherapy
How to Prepare and What to Expect
No special preparation is needed before a Cynodon dactylon allergy test. The process is straightforward and similar to any routine blood test.
Do You Need to Fast?
No, fasting is not required. You can eat and drink as you normally would before your appointment.
Practical Tips Before Your Test
A few simple steps can help ensure your sample is collected without any issues:
- Tell your doctor about all medicines, vitamins, herbal products, and supplements you are currently taking
- Let your doctor know if you are on antihistamines or anti-inflammatory medicines, as these may affect your results
- Wear a short-sleeved or loose-sleeved top for easy access to your arm
- There are no dietary restrictions; continue your normal routine
Step-by-Step Procedure
Here is what typically happens during your sample collection:
- A trained phlebotomist ties an elastic band around your upper arm to make your veins easier to locate.
- You will be asked to make a fist to help the vein fill with blood.
- The skin on the inside of your elbow is cleaned with an antiseptic wipe.
- A small needle is inserted into the vein, and a blood sample is drawn into a collection tube.
- The needle is removed, and gentle pressure is applied to the site. The whole process takes only a few minutes.
- The sample is sent to the laboratory, where the serum is separated and analysed within 24 hours to 3 working days.
Factors That Can Affect Accuracy
Certain factors may affect the reliability of your test result:
- Haemolysed (damaged red blood cells), icteric (yellowed), or lipemic (fatty) blood samples may be rejected
- Very high total IgE levels (above 2,500 kU/L) may produce false-positive readings
- Timing relative to the local pollen season and recent allergen exposure can influence results
- Ongoing or past allergen immunotherapy may affect how results are interpreted
Understanding Your Bermuda Grass Allergy Test Results
Your result will show a specific IgE level in kU/L, which is then placed into a class (0 to 6) indicating the degree of sensitisation. A doctor should always review your results alongside your symptoms and medical history.
| IgE Level (kU/L) | Class | Interpretation |
|---|---|---|
| Less than 0.35 | 0 | Negative; no sensitisation detected |
| 0.35 to 0.69 | 1 | Low or equivocal |
| 0.70 to 3.49 | 2 | Moderate sensitisation |
| 3.50 to 17.49 | 3 | High sensitisation |
| 17.50 to 49.99 | 4 | Very high sensitisation |
| 50.00 to 99.99 | 5 | Very high sensitisation |
| 100.00 and above | 6 | Extremely high sensitisation |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can make results harder to interpret:
- Patients with markedly elevated total IgE levels (above 2,500 kU/L) may show false-positive results, and the clinical picture must be taken into account.
- Cross-reactive carbohydrate determinants (CCDs), which are sugar structures found in many plant proteins, can sometimes cause a positive result that has no real clinical significance.
- IgE levels reflect sensitisation but may not always match the severity of your actual symptoms.
How to Maintain Healthy Levels
These general tips can help reduce your exposure to Bermuda grass pollen:
- Check local pollen counts and try to stay indoors during peak pollen hours, typically late spring to early autumn in tropical regions.
- Keep windows closed on high-pollen days and consider using an air purifier indoors.
- Shower and change clothes after spending time outdoors to remove pollen from your hair and skin.

Frequently Asked Questions
Bermuda grass is a warm-season perennial grass widely used as lawn cover and forage across tropical and subtropical regions, including much of India. It releases large quantities of wind-borne pollen that is considered highly allergenic. When a sensitive person breathes in this pollen, their immune system produces IgE antibodies, triggering allergy symptoms.
The Cynodon dactylon allergy test detects IgE antibodies directly from a blood sample using the ImmunoCAP FEIA method. Unlike a skin prick test, it does not require you to stop taking antihistamines beforehand and carries no risk of a skin reaction during the test itself.
Yes, you can eat and drink normally before your appointment. No fasting or dietary changes are needed before this grass pollen allergy test (Bermuda).
Yes. Bermuda grass pollen shares similar proteins with other grasses, so cross-reactivity with Timothy, rye, Johnson, and other grasses is possible. Some people also experience Oral Allergy Syndrome, where similar proteins in certain fresh foods such as melon, tomato, or citrus fruits trigger mild mouth or throat irritation. Speak to your doctor if you notice such symptoms.
Yes. Children can be affected by Bermuda grass allergy at any age and can safely undergo this blood test. A small blood sample is all that is required, and the procedure is the same as for adults.
Not always. A result below 0.35 kU/L suggests that sensitisation to Bermuda grass is unlikely, but a negative IgE test does not completely rule out an allergic reaction. Your doctor will consider your symptoms and full clinical history alongside the result before reaching any conclusion.
This test can be done at any time of year. Your doctor will usually decide the timing based on your age, your symptom history, and the season in which your symptoms tend to appear.
