Details about Individual Allergen
What is the Individual Allergen test?
The Individual Allergen test, also known as a specific IgE test, measures the immune system’s response to one specific allergen. This could be a food, pollen, animal dander, mould, insect venom, or environmental substance.
When the body is sensitised to an allergen, it produces IgE antibodies directed specifically against that trigger. Measuring allergen-specific IgE allows targeted identification of allergic sensitisation rather than general allergy tendency.
This test is commonly used when symptoms point to a particular suspected allergen and precise identification is required.
Why do I need an Individual Allergen test?
Identifying the exact allergen responsible for symptoms allows targeted avoidance, treatment, and improved symptom control.
You may need an Individual Allergen test if you:
- Have symptoms after eating a specific food
- Experience seasonal allergy symptoms
- React to pets, dust, mould or pollen
- Have eczema, asthma or hay fever
- Have unexplained allergic reactions
- Need confirmation of a suspected allergen
- Want to avoid broad or unnecessary testing
Symptoms commonly linked to allergen sensitisation include:
- Sneezing and nasal congestion
- Itchy or watery eyes
- Skin rashes or hives
- Digestive discomfort after foods
- Wheezing or shortness of breath
- Swelling of lips, face or throat
Benefits of the Individual Allergen test
- Pinpoints the exact allergen
Focused testing for specific triggers. - More precise than total IgE testing
Identifies individual sensitisation. - Supports targeted avoidance strategies
Improves symptom control. - Useful for food and environmental allergies
Wide range of allergens available. - Clinically recognised diagnostic tool
Used in allergy and immunology care. - Safe and non-exposure based
No need to provoke allergic reactions. - Supports asthma and eczema management
Identifies underlying allergic drivers. - Simple blood test
No skin testing required.
Step by step – how the test works
You can access Individual Allergen testing UK-wide through two options:
- Clinic appointment
Attend your nearest UK clinic, where a healthcare professional will take your blood sample. - At-home or hotel visit (£60 extra)
A qualified phlebotomist comes to your home or hotel, so you don’t need to travel.
Your blood sample is analysed in an accredited UK laboratory for allergen-specific IgE, and results are delivered securely.
Your results explained
Low or undetectable specific IgE
No sensitisation detected to the tested allergen.
Typical UK interpretation:
- < 0.35 kUA/L
Moderate specific IgE levels
Indicates sensitisation; symptoms may occur on exposure.
Typical UK interpretation:
- 0.35–3.5 kUA/L
High specific IgE levels
Strong sensitisation with higher likelihood of clinical reaction.
Typical UK interpretation:
- > 3.5 kUA/L
Clinical symptoms and exposure history are essential when interpreting results.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
