Details about Extended Allergy Panel
What is the Extended Allergy Panel?
The Extended Allergy Panel is a comprehensive blood test measuring specific IgE antibodies to a broad range of food, environmental, animal, mould, pollen, and indoor allergens. It is designed for individuals with complex, persistent, or unexplained allergy symptoms.
This panel includes allergens from multiple categories:
Environmental & Pollens
Willow, Grey alder, Common silver birch, Hazel tree, Oak, Beech, Walnut tree, Maple leaf sycamore/London plane, Plantain (English/Ribwort), Mugwort, Meadow fescue, Timothy grass, Orchard grass, Perennial rye grass, June grass, Rye flour, Oat, Maize (corn)
Moulds & Fungi
Aspergillus fumigatus, Alternaria alternata, Penicillium chrysogenum (P. notatum), Cladosporium herbarum, Candida albicans
House Dust Mites
Dermatophagoides pteronyssinus, Dermatophagoides farinae
Animal & Pet Dander / Epithelium
Cat dander, Dog dander, Dog epithelium, Horse dander, Cow dander, Rabbit epithelium, Guinea pig epithelium, Hamster epithelium

Total Allergy Marker
Total IgE
This broad coverage makes it one of the most comprehensive IgE allergy panels available.
Why do I need an Extended Allergy Panel?
Many people react to multiple allergens simultaneously, and symptoms may not clearly point to a single trigger. This panel is ideal when standard allergy testing has been inconclusive or symptoms persist despite dietary or environmental changes.
You may benefit from this test if you experience:
-
Chronic rhinitis or sinus symptoms
-
Eczema, hives, or unexplained rashes
-
Digestive symptoms after eating
-
Asthma or breathing difficulties
-
Seasonal allergy symptoms year-round
-
Suspected multiple food sensitivities
-
Pet-related allergy symptoms
-
Poor response to antihistamines
Benefits of the Extended Allergy Panel

Useful for adults and children
Suitable across age groups. -
Includes Total IgE for context
Helps interpret overall allergic tendency. -
Reduces diagnostic guesswork
One test instead of multiple smaller panels. -
Supports specialist allergy management
Useful before referral or treatment planning.

Your Extended Allergy Panel results explained
Negative IgE results
No detectable IgE sensitisation to the tested allergens. IgE-mediated allergy is unlikely, though non-IgE reactions may still exist.
UK reference interpretation:
-
Negative: <0.35 kUA/L
Low to moderate IgE sensitisation
Indicates allergic sensitisation with variable symptom severity. Clinical history is essential for interpretation.
UK reference interpretation:
-
Positive: ≥0.35 kUA/L
High IgE levels
Suggests strong sensitisation and increased likelihood of clinical allergy, especially if symptoms are present.
UK reference interpretation:
-
High: Significantly elevated IgE

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.
