What is an Allergy, Pear Test?
The Allergy, Pear test measures the level of Pear-specific immunoglobulin E (IgE) antibodies in your blood. IgE is a protein your immune system produces when it mistakenly treats Pear proteins as harmful. Doctors order this test when a patient reports symptoms after eating Pears or related foods. It is also known as the Pear IgE Test or Pyrus communis IgE Test.
What Does an Allergy, Pear Test Measure?
This test analyses one specific marker in your blood. The table below explains what it detects.
| Parameter | What it Detects |
|---|---|
| Pear-Specific IgE Antibodies | The level of IgE antibodies that react to Pear proteins, indicating sensitisation to Pear allergens |
A higher level of these antibodies suggests a greater likelihood that your immune system reacts to Pear. Results are reported in kU/L and grouped into classes from 0 (negative) to 6 (very high positive).
Why is an Allergy, Pear Test Done?
This test is ordered when a doctor suspects a Pear allergy based on your symptoms or medical history. It helps confirm whether your immune system is producing IgE antibodies against Pear proteins.
Common Symptoms That May Require This Test
The following symptoms after eating Pears may prompt your doctor to request this test:
- Itching or burning sensation in the lips, mouth, ears, or throat
- Skin rashes or hives
- Facial swelling, particularly around the lips
- Nausea or digestive discomfort
- Difficulty breathing
- Perioral redness (redness around the mouth)
- Generalised allergic reaction
Conditions This Test Can Help Detect
This test can help identify or support the diagnosis of several conditions:
- Pear allergy (IgE-mediated food allergy)
- Pollen-food allergy syndrome (PFAS), also called oral allergy syndrome (OAS)
- Cross-reactivity with other fruits in the Rosaceae family, such as apples and peaches
- Birch pollen-related food hypersensitivity
How to Prepare and What to Expect
No special preparation is needed for the Allergy, Pear test. The process is straightforward and takes only a few minutes.
Do You Need to Fast?
No, fasting is not required before this test. You can eat and drink normally beforehand. If your doctor has ordered additional tests alongside this one, check whether those require fasting.
Practical Tips Before Your Test
A few simple steps will help ensure a smooth sample collection:
- Bring a detailed clinical history, including your symptoms, previous test results, and any family history of allergies, as this is required for the test
- Inform your doctor about all medications you are currently taking, particularly antihistamines, as these may affect results
- Drink plenty of water before your appointment to make the blood draw easier
- Wear clothing with sleeves that can be rolled up comfortably
Step-by-Step Procedure
Here is what to expect during a standard blood collection for the Pear IgE Test:
- A trained phlebotomist will ask you to sit comfortably and extend your arm.
- An elastic band is tied around your upper arm to help the veins become more visible. You may be asked to make a fist.
- The skin over the vein is cleaned with an antiseptic wipe to prevent infection.
- A small needle is gently inserted into the vein, and about 3 ml of blood is drawn into a labelled collection tube.
- The needle is removed, and a small cotton swab is placed over the site. The whole process usually takes under five minutes.
- Your sample is stored under refrigeration and sent to the laboratory for analysis using the FEIA (fluorescent enzyme immunoassay) method.
Factors That Can Affect Accuracy
Several factors may influence the reliability of your test result:
- Taking antihistamines or other allergy medications before the test
- A recent severe allergic reaction
- Very high total IgE levels in the blood (above 2,500 kU/L), which can occasionally cause false-positive readings
- Recent immunotherapy treatment for allergies
- Parasitic infections, which can elevate overall IgE levels
- Improper sample handling or storage
Understanding Your Allergy, Pear Test Results
Your result will be reported as a class and an IgE concentration in kU/L. The table below outlines the standard reference ranges. Always review your results with your doctor.
| Class | IgE Level (kU/L) | Interpretation |
|---|---|---|
| 0 | Less than 0.35 | Negative (no sensitisation detected) |
| 1 | 0.35 to 0.69 | Low or weak positive |
| 2 | 0.70 to 3.49 | Moderate positive |
| 3 | 3.50 to 17.49 | High positive |
| 4 | 17.50 to 49.99 | Very high positive |
| 5 | 50.00 to 100 | Very high positive |
| 6 | Greater than 100 | Very high positive |
A result at Class 2 or above (0.70 kU/L or more) is generally considered clinically significant when combined with a history of symptoms after eating Pear. A negative result means no detectable sensitisation to Pear was found, though your doctor may still investigate other causes of 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
Birch pollen cross-reactivity can affect how your results are interpreted.
- Pollen-Food Syndrome: People who are allergic to birch pollen may also show positive IgE responses to a wide range of raw fruits and vegetables, including Pears, apples, peaches, cherries, and hazelnuts.
- Effect of Cooking: Cooking or heating Pears changes the protein structure, which means some people with oral allergy syndrome may not react to cooked Pears in the same way.
How to Maintain Healthy Levels
If you are managing a confirmed Pear allergy, the following general tips may help:
- Avoid raw Pears and products containing Pear if you have been diagnosed with a Pear allergy.
- Try cooking or baking Pears, as heat can alter the proteins responsible for reactions in some individuals with oral allergy syndrome. This may not work for everyone.
- Keep a food and symptom diary to identify other potential trigger foods, especially those in the same fruit family.

Frequently Asked Questions
The Allergy, Pear test measures Pear-specific IgE antibodies in your blood to determine whether your immune system reacts to Pear proteins. It is ordered when a doctor suspects a Pear allergy based on symptoms such as mouth itching, hives, or swelling after eating Pears.
No fasting is needed before this test. You can eat and drink as usual on the day of your appointment. Simply bring your clinical history and inform the phlebotomist of any medications you are taking.
Yes, this is quite common. A large proportion of people with birch pollen allergy also react to raw Pears and related fruits due to cross-reactive proteins. This is called pollen-food syndrome or oral allergy syndrome. A positive Pear IgE test result in this context should be discussed with your doctor.
For people with oral allergy syndrome, heating Pears can break down the proteins that trigger reactions, and cooked Pears may be tolerated. However, this does not apply to everyone, particularly those with a primary Pear allergy rather than cross-reactive pollen sensitivity.
Pears belong to the Rosaceae fruit family. People with a Pear allergy often also react to apples, peaches, cherries, and apricots due to shared proteins. This cross-reactivity is worth discussing with an allergist.
Results are typically available within 3 days of sample collection at Lupin Diagnostics. You will receive your report digitally once it is ready.
Both tests check for allergic sensitisation, but they work differently. A blood test, like the Allergy, Pear test procedure offered here, measures IgE antibodies in your serum and may be preferred if you are on antihistamines, have sensitive skin, or wish to avoid the discomfort of skin prick testing. Your doctor will recommend the most appropriate option based on your situation.
