Who is this private allergy test suitable for?

People often come to us after months or years of symptoms without clear answers. This test may help if you experience:

Food-related reactions

  • Bloating, cramps, diarrhoea, nausea or vomiting after eating

  • Tingling, itching or hives after certain foods

  • Suspected nut, sesame, milk, egg, wheat, soya, fish or shellfish allergy

Persistent sinus or hay fever symptoms

  • Congestion, sneezing, itchy or watery eyes

  • Seasonal triggers (tree/grass pollen) or year-round triggers (dust mites, pets, mould)

Asthma or breathing symptoms

  • Coughing, wheezing or chest tightness that worsens around pets, dust, or pollen

Skin conditions

  • Eczema flare-ups linked to foods or environment

  • Urticaria (hives) and skin itching

Digestive symptoms

  • Rapid gastrointestinal reactions to food exposure

Unexplained allergy-like illness

  • Previous testing inconclusive

  • IgG “food sensitivity” tests caused confusion or unnecessary food restriction

If that sounds familiar, you are not alone. Many patients reach us after GP appointments, elimination diets or OTC allergy treatments have not resolved symptoms.


Understanding IgE: the difference between allergy and intolerance

This test measures IgE antibodies, the immune mechanism involved in true immediate allergy. When someone with IgE antibodies meets an allergen, they may develop:

  • Skin symptoms: itching, hives, swelling

  • Nasal/respiratory symptoms: runny nose, sneezing, wheezing or coughing

  • Digestive symptoms: vomiting, diarrhoea, cramping

  • Severe reactions: breathing difficulty (medical emergency)

Allergy vs Intolerance (important to know)

Food Allergy (IgE) Food Intolerance (Non-IgE / Digestive)
Immune-driven (IgE antibodies) Often digestive/non-immune
Reaction within minutes Reaction may take hours/days
Can be severe or life-threatening Usually not dangerous
Tested with IgE blood/skin tests Investigated via diet/breath tests
Peanut, egg, milk, seafood Lactose intolerance, IBS, FODMAP triggers

The ALEX² test does not diagnose intolerances such as lactose intolerance, IBS, histamine intolerance or FODMAP sensitivity.


About the ALEX² Allergy Explorer Test (Advanced IgE & Component Testing)

This test uses multiplex macroarray technology to measure IgE to:

  • 120+ whole allergen extracts

  • 170+ molecular allergen components, helping differentiate:

    • True primary food allergy (storage proteins) vs

    • Pollen-food cross-reactions (Oral Allergy Syndrome)

This test can help answer questions such as:

  • Is my nut allergy high-risk or pollen-related?

  • Am I reacting to dust mites, pets, moulds or multiple inhalant allergens?

  • Are my fruit/veg reactions linked to birch or grass pollen?


What allergens are included?

This panel screens for sensitisation to allergens across major groups:

🌿 Airborne & Environmental Allergens

  • Grass, tree and weed pollens

  • House dust mites & storage mites

  • Moulds & yeasts

  • Pet dander: cat, dog, horse, rabbit, rodents, farm animals

🥛 Food Allergens

  • Cow’s milk, egg (white & yolk)

  • Peanut & tree nuts with component breakdown

  • Sesame, soya, lentils, chickpea, lupin

  • Wheat, rye, barley, oats, rice, maize

  • Fish & shellfish

  • Fruits, vegetables, spices, herbs

🐝 Other Allergen Groups

  • Latex

  • Insect venoms (bee, wasp)


ALEX² vs other allergy testing methods

Test Type Strengths Limitations
ALEX² 295 IgE Panel Broad, one blood draw, component-level insight Requires clinician interpretation
Single-Allergen IgE Useful when a specific allergy is known Not ideal for complex cases
Skin Prick Test Immediate results Antihistamines must be stopped
IgG Food Sensitivity Tests Marketed for “intolerances” Not recommended by allergy specialists/NICE

Before your appointment (pre-test guidance)

Simple and convenient:

  • No fasting required

  • Antihistamines can usually be continued

  • No need to avoid foods or allergens before the test

A brief clinical history is taken before blood sampling.
