Struggling with unexplained symptoms? Our consultant allergist uses the ALEX IgE blood test — screening 282+ allergens in a single blood draw — to give you a definitive diagnosis and a clear path to feeling better.
From first contact to a personalised treatment plan, here is exactly what to expect when you come to The Wellness People for allergy testing and treatment.
Sit down with our allergist to discuss your symptoms, medical history, and potential triggers. We determine the most appropriate testing approach for your specific presentation.
A single blood draw is taken. The ALEX test simultaneously screens 282 allergen extracts and molecular allergens — the most comprehensive panel available in one test.
Your allergist walks through your results in a dedicated follow-up session, explaining your specific sensitisation profile in clear, plain terms.
Based on your results, we create a tailored management plan — covering avoidance strategies, medication options, and referral for immunotherapy where appropriate.
The ALEX (Allergy Explorer) is a next-generation in vitro multiplex allergy test that simultaneously measures total IgE (tIgE) and specific IgE (sIgE) across a comprehensive panel of allergen extracts and molecular allergens.
Unlike basic allergy blood tests, the ALEX panel identifies which specific molecular proteins you are reacting to — not just whether a reaction exists. This is critical for distinguishing true food allergies from cross-reactive responses (such as oral allergy syndrome), and for determining whether immunotherapy (desensitisation) is likely to be beneficial.
The molecular data also helps predict the severity of future reactions and identifies patients with cross-reactive allergen groups such as profilins, LTPs, tropomycins, and CCDs.
What does this mean for you? Rather than receiving a vague positive result, you receive a detailed sensitisation map — helping your allergist make precise, evidence-based decisions about your treatment and lifestyle adjustments.
Allergic conditions can present at any age and in many different forms. Private allergy testing is appropriate whenever unexplained symptoms are affecting your quality of life.
Milk and soy allergies are among the most common in infants. As children wean onto solids, reactions to eggs, nuts, wheat, and shellfish often emerge as eczema, hives, or digestive symptoms. Early diagnosis is essential for healthy growth and development.
Chronic allergy symptoms — itchy eyes, rhinitis, asthma, eczema — can significantly impact school performance, sport, and social wellbeing. Definitive diagnosis at this stage allows for targeted management before symptoms become entrenched.
Adults may carry allergies from childhood or develop new sensitivities over time. Unexplained hives, digestive issues, nasal symptoms, or even anaphylaxis all warrant formal testing. Early detection reduces anxiety and helps restore normal daily functioning.
Our allergy testing panel covers the full range of IgE-mediated allergic conditions. If you are experiencing any of the following, a formal diagnosis is the first step to effective management.
A positive allergy test result is not the end of the journey — it is the beginning. Once we understand precisely what you are reacting to and why, we build a personalised management plan that may include one or more of the following approaches.

For many allergens — particularly food triggers — the most effective management begins with structured avoidance. Your allergist will provide specific, practical guidance on minimising exposure based on your sensitisation profile, going beyond generic elimination advice.

Antihistamines, nasal sprays, and bronchodilators all have a role in managing allergic symptoms. Your allergist will advise on the most appropriate pharmaceutical options for your condition — including when and how to use them most effectively.

For certain allergens — including pollen, dust mites, and insect venom — allergen immunotherapy can reduce or eliminate the allergic response over time. Your molecular test results help determine whether you are a suitable candidate for desensitisation.

For patients at risk of anaphylaxis or severe reactions, we provide detailed emergency action plans, including guidance on the appropriate use of adrenaline auto-injectors (such as EpiPen), and ensure you and your family are fully informed.
We are proud to have helped hundreds of patients in London gain clarity on their allergies and take back control of their health.

Book a consultation with our London allergist today and take the first step towards a definitive diagnosis.

Sit down with our highly qualified allergist in London to discuss your history, concerns, and symptoms as well as the most suitable methods of testing and treatment.

A follow-up session with our allergy specialist to discuss your test results and treatment options.

The new ALEX test (Macro-Array Diagnostics, of Vienna, Austria) comprises 126 component allergens plus 156 native allergens, totalling 282 tests, supplemented with total IgE, ALEX ® which can cover over 99% of the need for routine allergy diagnosis.
This test covers 167 different natural allergens (more than 150 allergen extracts and more than 100 molecular allergens including pollen, mould, fungus associated with atopic dermatitis and other skin diseases – mites, pets, insects, and a range of foods).
This detailed allergen panel is not only useful for researching specific allergens for individual patients but is also a comprehensive and definitive allergen screening test for suspected allergic patients.
ALEX ® Allergy Explorer is the first and most scientifically advanced in vitro multiplex allergy test allowing simultaneous measurement of total IgE (tIgE) and specific IgE (sIgE) against a plethora of allergen extracts and molecular allergens.
Based on our test panel’s composition of allergen extracts and molecular allergens, a near complete picture of each patient’s sensitization status is obtained. ALEX ® is based on our proprietary nano-bead technology and is the new generation gold standard of in vitro tests for Type I allergies.
These component lgE antibody screening tests are very useful in people who suffer with multiple food and inhalant allergies and helps identify to which group or groups of allergens they are cross reacting to such as profilins, LTPs, Tropomycins or CCDs. Once their cross- reactive allergen groups are identified, one can predict severity of future reactions and whether they would benefit from desensitization immunotherapy.

Most symptoms in babies are due to milk related allergies. As their diet expands to include solids, toddlers may have allergies to soy, egg, shellfish, nuts or wheat. Theses allergies often show up as eczema, urticaria/hives and other gastrointestinal symptoms such as diarrhea, bloating and discomfort. Testing and definitive diagnosis at the earliest opportunity is essential to ensuring normal nutrition, growth and development.
Allergic symptoms can present as itchy eyes, runny noses/rhinitis, wheeze or asthma and eczema or hives. At this crucial school-going age, chronic symptoms can negatively affect quality of life, ability to do sports and stay active and academic performance.
Once again, testing and definitive diagnosis at the earliest opportunity is essential.


Adults can be affected by either persisting allergies from childhood or by new and developing allergies which can result in a huge variety of symptoms including hives, eczema and even anaphylaxis.
To reduce the anxiety and stress surrounding these symptoms and allow a normal quality of life with minimal disruption to work and daily routines, early detection is essential.
