What is an Allergy, Cheese Test?
The Allergy, Cheese test measures the level of specific IgE (immunoglobulin E) antibodies in your blood directed against cheese proteins. When your immune system mistakenly identifies cheese proteins as harmful, it produces these antibodies, which can trigger allergic symptoms. A doctor may order this test if you experience symptoms after eating cheese or other dairy products. It is also known as the Cheese Allergy IgE Test or Cheddar Cheese Allergy Test.
What Does an Allergy, Cheese Test Measure?
This test analyses one key marker in your blood. The table below explains what it looks for:
| Parameter | What It Indicates |
|---|---|
| Specific IgE antibodies to cheese proteins | Whether your immune system has produced allergy-causing antibodies in response to cheese proteins |
The test works by adding cheese proteins to your blood sample in the laboratory. If your immune system has reacted to cheese before, IgE antibodies will be present. These antibodies trigger the release of histamine and other chemicals that cause allergic symptoms.
Why is an Allergy, Cheese Test Done?
A doctor may recommend the Allergy, Cheese Test for several reasons. It helps confirm whether symptoms are linked to cheese consumption and guides further management.
Common Symptoms That May Require This Test
The following symptoms, when noticed after eating cheese, may prompt a doctor to order this test:
- Tingling or itching around the mouth
- Hives or skin rash
- Swelling of the lips, tongue, or throat
- Nausea, abdominal discomfort, or diarrhoea
- Nasal congestion or a runny nose
- Coughing or difficulty breathing
Conditions This Test Can Help Detect
This test can help identify the following conditions:
- Cheese allergy caused by proteins in the milk used to make cheese
- Cow's milk protein allergy, one of the most common food allergies in children
- Sensitisation to casein or whey proteins, the two main allergenic protein groups in milk
- Cross-reactivity with other dairy products such as butter, yoghurt, and milk
How to Prepare and What to Expect
No special preparation is needed before the Allergy, Cheese test procedure. The steps below outline what to expect on the day of collection.
Do You Need to Fast?
No fasting is required for this test. IgE levels do not fluctuate significantly based on meal timing, so you can eat and drink normally before your appointment.
Practical Tips Before Your Test
Keep the following points in mind before your sample is collected:
- Bring a detailed clinical history, including your symptoms, previous test results, and any known allergies, as this is required for the test.
- Inform your doctor about all medications and supplements you are taking.
- Stay well hydrated before the test, as this makes blood collection easier.
- You do not need to stop antihistamines before a blood IgE test, unlike a skin-prick allergy test. However, always inform the doctor about any medicines you take.
- Blood is ideally collected in the morning, though this is not mandatory.
Step-by-Step Procedure
Here is what happens during the Allergy, Cheese test procedure:
- You arrive at the collection centre, or a phlebotomist visits your home.
- Your arm is cleaned with an antiseptic, and a thin needle is used to draw a small blood sample from a vein.
- Approximately 3 ml of blood is collected into a yellow gel tube (SST gel tube).
- The sample is stored at refrigeration temperature (2 to 8°C) and dispatched to the laboratory.
- In the lab, cheese proteins are introduced to your serum sample, and specific IgE antibody levels are measured using the FEIA (Fluorescence Enzyme Immunoassay) method.
- Results are typically ready within 3 days.
Factors That Can Affect Accuracy
Several factors may influence the reliability of your results:
- Recent exposure to cheese or dairy products
- High total IgE levels in the blood, which may require sample dilution
- Other allergic conditions such as atopic eczema or allergic asthma
- Poor sample storage or delays in transport
- Presence of cross-reactive carbohydrate determinants (CCDs), which can occasionally cause falsely elevated readings with no clinical significance
Understanding Your Allergy, Cheese Test Results
Your results will be reported as a grade (0 to 6) and as a specific IgE level in kU/L. Always review your results with a qualified doctor who can interpret them alongside your symptoms and medical history.
| Grade | Specific IgE Level (kU/L) | Interpretation |
|---|---|---|
| 0 | Less than 0.35 | Negative (no detectable sensitisation) |
| 1 | 0.35 to 0.70 | Weak positive |
| 2 | 0.70 to 3.50 | Positive |
| 3 | 3.50 to 17.5 | Positive |
| 4 | 17.5 to 52.5 | Strong positive |
| 5 | 52.5 to 100 | Strong positive |
| 6 | Greater than 100 | Strong positive |
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 conditions can affect how results are interpreted:
- Conditions that elevate total IgE levels (such as atopic eczema, allergic asthma, or parasitic infections) may influence specific IgE readings and should be communicated to your doctor.
- A positive result does not automatically confirm that you will experience symptoms upon eating cheese; clinical assessment remains essential for a full diagnosis.
How to Maintain Healthy Levels
If your results suggest a cheese allergy, the following general steps can support your well-being:

Frequently Asked Questions
A cheese allergy is an immune system reaction to proteins in cheese or the milk used to make it. Lactose intolerance, on the other hand, is the inability to digest lactose (the natural sugar in milk) due to low enzyme levels. Allergy symptoms are typically more serious and can involve the skin, respiratory system, and digestive system, whereas lactose intolerance mainly causes bloating, cramps, and diarrhoea.
Most reactions occur within 30 minutes to two hours of eating cheese, though some delayed reactions are also possible. Symptoms may affect the skin, digestive system, or respiratory system, depending on the individual.
Yes. Research indicates that around 80% of children outgrow their milk (and cheese) allergy by age 16. Periodic retesting of specific IgE levels can help a doctor assess whether tolerance has developed over time.
No. Unlike skin-prick allergy tests, blood IgE tests are not affected by antihistamines. You do not need to stop taking them before this test, but do inform your doctor about all medicines you are taking.
It is uncommon to be allergic to only one variety. Because cheese allergies are driven by the proteins in the milk used to make cheese, people who react to one type are generally likely to react to other types as well.
Not necessarily. A raised IgE level confirms that your immune system has produced antibodies against cheese proteins, but this does not always mean symptoms will occur. Clinical correlation with your actual symptoms is essential before a diagnosis is made.
Bring a detailed clinical history, including your symptoms, any previous allergy test results, and a list of medications you take. This information is required for accurate processing of the Allergy, Cheese Test and helps your doctor interpret results correctly.
