What is an Allergy, Bahia Grass Test?
The Allergy, Bahia grass test is a blood test that checks whether your immune system reacts to Bahia grass pollen. It measures a specific type of antibody called IgE, which the body produces when it treats a substance as a threat. Also known as the Bahia Grass IgE Test or Paspalum notatum Allergy Test, it is typically ordered when a doctor suspects grass pollen as the cause of recurring allergy symptoms. A small serum sample drawn from a vein is used for the analysis.
What Does an Allergy, Bahia Grass Test Measure?
This test detects and measures Bahia grass-specific IgE antibodies in your blood. When Bahia grass pollen enters the body of a sensitised person, immune cells release chemicals such as histamine that trigger allergy symptoms. The test quantifies the level of IgE antibodies present and assigns them to a class, helping doctors understand the degree of sensitisation.
| Parameter | What it Indicates |
|---|---|
| Bahia Grass-Specific IgE (kUA/L) | The amount of IgE antibody directed at Bahia grass pollen; used to classify the level of sensitisation from Class 0 (none) to Class 6 (very high) |
Why is an Allergy, Bahia Grass Test Done?
Doctors order this test when a patient's allergy symptoms point to grass pollen as a possible trigger. It helps confirm sensitisation and guides further management.
Common Symptoms That May Require This Test
The following symptoms are among the most common reasons a doctor may request an Allergy, Bahia grass test:
- Frequent sneezing, especially outdoors or during warmer months
- Nasal congestion or a persistently runny nose
- Itchy, watery, or red eyes
- A scratchy or irritated throat
- Swelling around the face and eyes
- Worsening symptoms during the spring or summer pollen season
Conditions This Test Can Help Detect
This test can help identify or confirm several allergy-related conditions:
- Allergic rhinitis (commonly called hay fever)
- Asthma triggered or worsened by grass pollen
- Allergic conjunctivitis (eye inflammation caused by an allergic reaction)
- The allergen responsible for a severe allergic episode, including anaphylaxis
- Sensitisation to Bahia grass before starting immunotherapy (a form of allergy desensitisation treatment)
How to Prepare and What to Expect
No special preparation is needed for this test, but a few steps will help ensure accurate results.
Do You Need to Fast?
No fasting is required for the Allergy, Bahia grass test. You can eat and drink normally before giving your blood sample, and the test can be done at any time of day.
Practical Tips Before Your Test
Keep the following points in mind before your appointment:
- Bring a detailed clinical history, including your symptoms, previous test results, and any known allergies, as this is required for the test.
- Tell your doctor or the phlebotomist about all medications you are currently taking, including antihistamines and anti-inflammatory drugs, as some of these can affect results.
- Inform the laboratory if you have any bleeding disorders.
- Drink enough water before your appointment to make the blood draw easier.
Step-by-Step Procedure
Here is what to expect during sample collection:
- A trained phlebotomist will clean the skin on the inside of your elbow or the back of your hand with a disinfectant.
- A tourniquet (a tight rubber band) is placed 3 to 4 inches above the chosen spot to make the vein more visible and easier to access.
- A sterile needle is gently inserted into the vein, and a small blood sample is drawn into a collection tube.
- Once enough blood has been collected, the needle is removed, and a bandage is placed over the puncture site.
- The blood sample is transferred into a serum gel tube and stored at 2 to 8°C for transport to the laboratory.
- The sample is dispatched to the NABL-accredited Lupin Diagnostics laboratory, where it is analysed using the FEIA (Fluorescent Enzyme ImmunoAssay) method.
Factors That Can Affect Accuracy
The following factors may influence your test results:
- Recent use of antihistamines or corticosteroid medications
- Very high total IgE levels in the blood (above 2,500 kU/L), which can cause false-positive readings
- Recent immunotherapy treatment for allergies
- Dehydration at the time of the blood draw
Understanding Your Allergy, Bahia Grass Test Results
Your results will show a specific IgE level in kUA/L along with an assigned class. A doctor should always review these values in the context of your full medical history and symptoms.
| Class | IgE Level (kUA/L) | Interpretation |
|---|---|---|
| Class 0 | Less than 0.35 | Negative (no detectable sensitisation) |
| Class 1 | 0.35 to 0.69 | Low positive |
| Class 2 | 0.70 to 3.49 | Moderate positive |
| Class 3 | 3.50 to 17.49 | High positive |
| Class 4 | 17.50 to 49.99 | Very high positive |
| Class 5 | 50.00 to 99.99 | Very high positive |
| Class 6 | 100.00 and above | Very high positive |
Reference values apply to all ages and both genders.
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 alter how results should be read.
Patients with total IgE levels above 2,500 kU/L may show false-positive results due to nonspecific binding in the test. A result should always be interpreted alongside clinical findings.
Some people with measurable IgE antibodies may not experience obvious allergy symptoms. Equally, a negative result does not completely rule out allergy if clinical suspicion remains high, and further allergen-specific testing may be considered.
How to Maintain Healthy Levels
These general wellness tips may help reduce exposure to Bahia grass pollen:
- Monitor daily pollen counts during allergy season (typically March to September) and limit outdoor time on high-count days; wearing a mask and sunglasses outdoors can also reduce exposure.
- Use an air purifier indoors to filter pollen from the air, and keep windows closed during peak pollen periods.
- Shower and change clothes after spending time outdoors to remove pollen from your hair and skin.

Frequently Asked Questions
Bahia grass (Paspalum notatum) is a warm-season perennial grass originally from South America. During spring and summer, it releases pollen that some people's immune systems mistakenly identify as harmful. This triggers the production of IgE antibodies and causes typical allergy symptoms.
Bahia grass typically releases pollen between March and September, with peak levels in May and June. People sensitive to grass pollen often notice their symptoms worsening during this period, particularly with outdoor exposure.
The blood test measures your IgE response in a laboratory using a serum sample, without exposing your body to the allergen directly. A skin prick test introduces small amounts of the allergen into the skin and can cause a local reaction. The blood test is generally preferred when skin tests are not suitable or practical.
Yes, cross-reactivity between grass pollens is common. If you are sensitised to grasses such as Bermuda, Timothy, or Johnson grass, there is a possibility that your immune system will also react to Bahia grass pollen, as these grasses share similar proteins.
Not necessarily. A result above 0.35 kUA/L indicates sensitisation, but sensitisation does not always lead to clinical symptoms. The likelihood of a reaction tends to increase with higher IgE levels, but the test alone cannot predict the severity of any future response.
Some people with grass pollen allergy experience what is known as Oral Allergy Syndrome (OAS), where the immune system reacts to proteins in certain foods that resemble pollen proteins. Foods that may trigger this cross-reaction include peaches, celery, melons, oranges, and tomatoes. Consult your doctor if you notice symptoms after eating these foods.
Yes, the test is suitable for all ages. Research has linked Bahia grass sensitisation to childhood asthma, and the test is recommended for children showing allergy or asthma symptoms, particularly during the grass pollen season.
