What Is a Timothy Allergy Test?
The Timothy allergy test is a blood test that measures the level of immunoglobulin E (IgE) antibodies specifically produced in response to Timothy grass pollen. IgE antibodies are proteins your immune system releases when it reacts to a substance it identifies as a threat. Doctors use this test to check whether a person is sensitised to Timothy grass, one of the most common outdoor pollen allergens. It is also known as the Timothy pollen allergy test or the g6 allergen test, and it uses a small sample of blood drawn from a vein.
What Does a Timothy Allergy Test Measure?
The Timothy Grass IgE test looks at one specific marker in your blood. Here is what that measurement tells your doctor:
| Parameter | What It Measures |
|---|---|
| Timothy-specific IgE antibodies | The quantity of IgE antibodies your immune system has made in response to Timothy grass pollen, reported in kU/L |
The result indicates whether your immune system has become sensitised to this particular pollen, and to what degree. Higher levels generally point to a stronger immune response to the allergen.
Why Is a Timothy Allergy Test Done?
This test is ordered when a doctor suspects that grass pollen may be triggering a patient's symptoms, or when confirming sensitisation before starting immunotherapy.
Common Symptoms That May Require This Test
The following symptoms are commonly associated with a possible grass pollen allergy:
- Itchy, watery eyes
- Runny or blocked nose
- Frequent sneezing
- Itchy throat, sinus
- Persistent cough or wheezing
- Fatigue during the pollen season
- Shortness of breath or chest tightness
Conditions This Test Can Help Detect
A Timothy allergy test can support the diagnosis or assessment of the following conditions:
- Seasonal allergic rhinitis, commonly known as hay fever.
- Asthma linked to airborne grass pollen exposure.
- Sensitisation to Timothy grass pollen, confirming an allergic basis before immunotherapy begins.
How to Prepare and What to Expect
Preparing for this test is simple and straightforward. No special steps are needed beforehand.
Do You Need to Fast?
No, fasting is not required for the Timothy pollen allergy test. You can eat and drink as normal on the day of your test. If your doctor has ordered additional tests alongside this one, check whether any of those require fasting.
Practical Tips Before Your Test
A few simple steps will help make your sample collection go smoothly:
- You may continue taking antihistamines, nasal sprays, and asthma medications as usual, since blood IgE levels are not affected by these.Inform your healthcare provider about all medications you are currently taking.
- Drink enough water before your appointment to stay well hydrated.
- Wear loose clothing with sleeves that roll up easily for comfortable blood collection.
Step-by-Step Procedure
Here is what you can expect during the Timothy allergy test procedure:
- A trained phlebotomist cleans the skin on your inner arm with an antiseptic wipe.
- A small needle is gently inserted into a vein.
- A few millilitres of blood are collected into a sterile tube.
- The needle is removed, and a small cotton pad or bandage is placed over the site.
- Your blood sample is labelled and sent to an NABL-accredited laboratory for analysis.
- In the lab, your serum is tested using a fluorescence-based method that detects and measures IgE antibodies specific to Timothy grass pollen.
Factors That Can Affect Accuracy
Certain conditions may influence the reliability of your result:
- Very high total IgE levels in the blood (above 2,500 kU/L) can cause a false-positive reading.
- Parasitic infections can elevate total IgE levels.
- Conditions affecting the immune system, such as primary immunodeficiency disorders, may alter results.
- Poor sample quality, such as haemolysed (with broken red blood cells) or lipemic (very fatty) blood samples.
Understanding Your Timothy Allergy Test Results
Your doctor will review your result alongside your symptoms and medical history. The table below shows how IgE levels are classified.
| Class | Specific IgE Level (kU/L) | Interpretation |
|---|---|---|
| Class 0 | Less than 0.10 | Negative (no sensitisation detected) |
| Class 0/1 | 0.10 to 0.35 | Borderline/Equivocal |
| Class 1 | 0.35 to 0.70 | Weak positive |
| Class 2 | 0.70 to 3.5 | Positive |
| Class 3 | 3.5 to 17.5 | Positive |
| Class 4 | 17.5 to 49.99 | Strong positive |
| Class 5 | 50.00 to 100 | Strong positive |
| Class 6 | Greater than 100 | Strong positive |
Results at Class 2 or above (0.70 kU/L or more) are flagged as elevated. A positive result indicates sensitisation to Timothy grass, but sensitisation is not the same as confirmed clinical disease. A negative result does not completely rule out an allergy, as other allergens may be responsible for your symptoms.
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
Some circumstances may influence how your result is read:
Patients with markedly elevated total IgE levels (above 2,500 kU/L) may see false-positive readings due to nonspecific binding in the test system. People with parasitic infections may also show elevated IgE unrelated to grass pollen allergy. Your doctor will take these possibilities into account when reviewing your result.
How to Maintain Healthy Levels
While there is no way to change your IgE response, these general steps may help reduce pollen exposure:
- Check daily pollen forecasts and stay indoors when grass pollen counts are high.
- Keep windows closed at home and in the car during the grass pollen season, typically late spring through summer.
- Shower and change clothes after spending time outdoors on high-pollen days.

Frequently Asked Questions
Timothy grass, known scientifically as Phleum pratense, is one of the most prevalent outdoor allergens worldwide. Its pollen triggers IgE responses in sensitised individuals, causing symptoms such as rhinitis and asthma. The major allergen in Timothy grass, called Phl p 1, causes an IgE reaction in most people who are allergic to it.
Timothy grass typically releases pollen between May and August, covering late spring through summer. In warmer regions, grass pollen can be present for a longer part of the year. People who are sensitised often notice their symptoms worsening during this period.
No. Unlike skin prick tests, this blood test measures IgE antibodies in your serum, which are not affected by antihistamines, nasal sprays, or asthma medications. You can continue your regular medications without any interruption before this test.
Yes, in some cases. Timothy grass allergy is associated with pollen-food allergy syndrome, where the immune system confuses proteins in certain foods with those in grass pollen. Foods such as celery, melons, oranges, peaches, and tomatoes may trigger mild reactions in people sensitised to grass pollen.
The Timothy allergy test is suitable for all ages, including young children. The only discomfort involved is the brief sting of the needle during blood collection and, occasionally, a small bruise at the site afterwards. The test itself carries no significant risk.
A result above 0.35 kU/L indicates that your immune system has produced IgE antibodies against Timothy grass pollen. This shows sensitisation, but it does not automatically confirm that you will experience symptoms or that a reaction will be severe. Your doctor will assess the result together with your clinical history before drawing any conclusions.
