What is an Allergy, Willow Test?
The Allergy, Willow test is a blood test that measures specific IgE (immunoglobulin E) antibodies produced by your immune system in response to willow pollen. IgE antibodies are proteins your body makes when it reacts to a substance it identifies as harmful. The test helps confirm whether willow pollen is the cause of your allergy symptoms. It is also called the Willow Pollen IgE test or Willow Tree allergy test.
What Does an Allergy, Willow Test Measure?
The test analyses a single key marker in your blood sample. Here is what it looks for:
| Parameter | What it Indicates |
|---|---|
| Willow-specific IgE antibodies | The level of immune response your body has developed to proteins found in willow pollen |
A higher level of these antibodies suggests your immune system is sensitised to willow pollen. The test is performed using the FEIA (fluorescent enzyme immunoassay) method, which accurately detects and quantifies IgE antibody levels in your serum.
Why is an Allergy, Willow Test Done?
Doctors order the Allergy, Willow test when a patient reports symptoms that appear during or worsen in specific seasons, particularly spring. It helps pinpoint whether willow pollen is the trigger.
Common Symptoms That May Require This Test
The following symptoms are common reasons a doctor may recommend this test:
- Frequent sneezing, especially outdoors or during spring
- Nasal congestion (stuffy nose, making it hard to breathe through the nose)
- Itchy, watery, or red eyes
- Postnasal drip (excess mucus draining down the back of the throat)
- Headaches linked to sinus pressure
- Itching of the skin, throat, or ears
- Wheezing or difficulty breathing
Conditions This Test Can Help Detect
This test can support the diagnosis of several allergy-related conditions:
- Seasonal allergic rhinitis (commonly known as hay fever)
- Allergic asthma triggered by tree pollen
- Rhinoconjunctivitis (simultaneous inflammation of the nose and eyes)
- Atopic dermatitis (eczema) linked to pollen exposure
The test also helps confirm sensitisation before a doctor considers starting immunotherapy (allergy desensitisation treatment).
How to Prepare and What to Expect
The Allergy, Willow test procedure is straightforward. Minimal preparation is needed, but following a few simple steps helps ensure your sample is collected correctly.
Do You Need to Fast?
No, fasting is not required before this test. You can eat and drink normally on the day of collection.
Practical Tips Before Your Test
Keep the following points in mind before your appointment:
- Bring a detailed clinical history, including your symptoms, any previous allergy test results, and details of seasonal triggers, as this is required for the test.
- Continue taking all regular medications, including antihistamines. Unlike skin prick tests, blood-based IgE testing is not affected by antihistamines.
- Drink adequate water before the test, as good hydration makes veins easier to access.
- Wear clothing with sleeves that roll up easily for a smooth blood draw.
- If you have previously felt faint during blood tests, inform the phlebotomist and consider having a light snack before your appointment.
Step-by-Step Procedure
Here is what happens during the Allergy, Willow test procedure:
- A trained phlebotomist cleans the skin over the selected vein, usually on the inside of the elbow.
- An elastic band is tied around the upper arm to make the veins more visible and accessible.
- A fine needle is gently inserted into the vein to draw a small blood sample of approximately 3 ml.
- Once the sample is collected, the needle is removed, and the puncture site is cleaned and covered with a small dressing.
- The blood sample is placed in a yellow SST gel tube and stored at refrigeration temperature (2 to 8°C) for transport.
- The sample is dispatched to a Lupin Diagnostics NABL-accredited laboratory, where it is tested using the FEIA method.
Factors That Can Affect Accuracy
Certain factors may influence your test result. These include:
- The patient's age (IgE levels vary across age groups)
- The season in which the test is taken (pollen exposure levels change throughout the year)
- Recent or past exposure to willow pollen
- Presence of parasitic infections or certain immune-related conditions, which can raise total IgE independently of pollen allergy
- The specific laboratory method used, as grading scales may differ slightly between labs
Understanding Your Allergy, Willow Test Results
Your results will show a numerical value in kU/L (kilo units per litre). The table below provides general reference ranges commonly used to interpret specific IgE results.
| Type of Test | Interpretation |
|---|---|
| Less than 0.35 | Negative (no sensitisation detected) |
| 0.35 to 0.69 | Low positive (low-level sensitisation) |
| 0.70 to 3.49 | Moderate positive |
| 3.50 to 17.49 | High positive |
| 17.50 to 49.99 | Very high positive |
| 50.00 and above | Very high positive |
Results of 0.70 kU/L or above are generally flagged as abnormally elevated.
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 conditions unrelated to pollen allergy can affect how results are interpreted:
- Parasitic infections, certain immune-related disorders, and some malignancies can raise total IgE levels, which may influence the interpretation of your result.
- A high total IgE must be read alongside your age, travel history, allergen exposure, and family history for an accurate picture.
- Results obtained outside of the willow pollen season (February to April) may appear lower, as allergen exposure is reduced.
How to Maintain Healthy Levels
These general wellness tips may help reduce your exposure to willow pollen:
- Stay indoors on high-pollen days, particularly in February to April when willow pollen levels peak in March.
- Use air purifiers with HEPA filters at home during the pollen season to reduce indoor allergen load.
- Shower and change clothing after spending time outdoors to remove pollen from your skin and hair.

Frequently Asked Questions
The Allergy, Willow test is a blood test that detects IgE antibodies specific to willow tree pollen. A doctor may prescribe it when you experience seasonal symptoms such as sneezing, nasal congestion, or watery eyes, especially during the spring months.
No fasting is required. You can eat and drink as you normally would before the test. There are no special dietary restrictions.
Yes. Unlike skin prick allergy tests, blood-based IgE tests are not affected by antihistamines. You can continue your regular medications without interruption.
Willow pollen is typically present from February to April, with levels peaking in March. Allergy symptoms linked to willow tend to be most noticeable during this window.
A positive result shows that your body has produced IgE antibodies against willow pollen, suggesting sensitisation. Your doctor will assess this alongside your symptoms to determine whether it points to an active allergy.
Possibly. There is known cross-reactivity between willow and poplar pollen, and some cross-reactivity with trees in the beech family. Your doctor can advise on whether further testing for related allergens is appropriate.
Yes, the test is safe for all age groups. A small blood sample is all that is needed. Reference ranges used to interpret results in children are adjusted for age, as IgE levels naturally vary across different stages of development.
