Could Allergies Be Behind Your Symptoms?

Allergies are far more common than many people realise. More than one in four people in the UK are affected by an allergy at some point in their lives, and the number continues to rise — particularly in adults who develop new allergies later in life. Symptoms are often dismissed or misattributed to other conditions, leaving people suffering unnecessarily for years. An untreated allergy can significantly impact your quality of life, your sleep, your energy levels, your ability to exercise, and your enjoyment of food and the outdoors. The frustrating truth is that without a comprehensive test, identifying the exact trigger can feel like finding a needle in a haystack. That is why we provide advanced allergy testing at Lambert Medical Practice — including the ALEX3, the most comprehensive specific IgE allergy test currently available in the UK — right here in Surbiton.

Do any of these sound familiar?

Persistent sneezing, runny nose, or nasal congestion — especially seasonal or around animals

Itchy, watery, or swollen eyes — worse outdoors or in dusty environments

Coughing, wheezing, or shortness of breath — triggered by environment or certain foods

Digestive symptoms after eating — bloating, nausea, vomiting, or diarrhoea

Skin reactions — hives, rashes, eczema flare-ups, or unexplained itching

Fatigue and brain fog — often overlooked symptoms linked to chronic allergic response

If you experience any of these, a comprehensive allergy test could provide the answers you have been searching for.

Book Your ALEX3 Test — £295

Allergy testing is particularly relevant for patients with hay fever, asthma, eczema, and food allergies. Speak to our GP team if you are unsure which test is right for you.

Who Should Consider the ALEX3 Allergy Test?

The ALEX3 is suitable for anyone experiencing unexplained symptoms that may be allergy-related. You do not need a GP referral. Here are some of the most common reasons patients book with us:

Hay Fever & Seasonal Symptoms

You suffer from sneezing, congestion, or itchy eyes during spring and summer but are not sure exactly which pollens are triggering your symptoms. Identifying specific pollen allergens can guide targeted treatment and immunotherapy options.

Suspected Food Allergies

You experience reactions after eating — hives, swelling, digestive upset, or tingling — but cannot pinpoint which food is responsible. The ALEX3 tests all major food allergens at molecular level, preventing unnecessarily restrictive elimination diets.

Eczema & Skin Conditions

Your eczema, urticaria, or dermatitis flares without a clear pattern. Allergic triggers are a common but often overlooked cause of chronic skin conditions. Identifying specific IgE sensitivities can significantly improve management.

Asthma & Respiratory Issues

Your asthma or breathing difficulties worsen in certain environments or seasons. Allergic asthma is extremely common, and identifying specific triggers — dust mites, moulds, animal dander, pollens — is essential for effective long-term management.

Pet & Animal Allergies

You suspect you are allergic to your cat, dog, or another pet but want to confirm before making life-changing decisions. The ALEX3 tests for specific molecular components within animal allergens, providing a more nuanced picture than basic testing.

Multiple or Unexplained Reactions

You react to seemingly unrelated things and have never had a comprehensive test. Cross-reactive molecular allergens often explain why patients react to multiple foods or environments — the ALEX3 is specifically designed to uncover these connections.

Why Patients Choose Lambert Medical Practice for Allergy Testing

Stop Guessing. Get a Complete Picture.

You are not alone if you have spent years avoiding foods you think might be a problem, or dreading the summer pollen season, or wondering why you feel worse in certain environments. Standard allergy testing often checks only a handful of allergens, leaving the majority of potential triggers untested. Our ALEX3 test screens 300 allergens in a single blood test — covering foods, pollens, animals, house dust mites, moulds, yeasts, insect venoms, and 218 specific molecular allergens. With one test, you receive a complete allergy profile that most other providers simply cannot match.

Professional Clinical Care, Not a Postal Kit

The difference between posting a home kit and visiting Lambert Medical Practice is significant. When you come to our CQC registered clinic in Surbiton, your blood sample is taken by our qualified phlebotomy nurse — ensuring a high-quality venous sample for the most accurate results. You have the opportunity to ask questions, discuss your symptoms, and receive guidance before you even leave the clinic. We are not just processing a postal order. We are your local, trusted medical team who will support you through the results process and beyond.

Molecular Allergen Testing Changes Everything

Most allergy tests on the market test for whole allergens — for example, whether you react to “apple.” The ALEX3 goes significantly further by also testing for the specific molecular components within each allergen — such as Mal d 1 or Mal d 3 in apple. This matters enormously because those same molecules are often found across multiple different foods and pollens. Understanding which molecule you are reacting to can explain why you react to seemingly unrelated foods, identify how severe your allergy risk is, enable highly targeted dietary advice rather than unnecessarily restrictive diets, and determine whether you might benefit from allergen immunotherapy.

300 Allergens — What Does That Cover?

The ALEX3 Allergy Xplorer covers 80 allergen families, 145 allergen sources, and 300 individual allergens — including 218 molecular allergens and 82 traditional allergen extracts. This breadth of coverage means that in a single blood draw, we can screen for virtually every major allergen category that affects people in the UK. From the seasonal pollen triggers that cause hay fever to the specific food proteins that trigger IgE responses, from cat and dog dander to house dust mites, moulds, insect venoms, and latex — the ALEX3 provides a complete allergic profile that gives you and your clinician the information needed to make confident decisions about your health.

Pollens

Timothy grass, rye grass, birch, oak, ash, olive, mugwort, ragweed, plantain, and many more seasonal tree, grass, and weed pollens — the primary cause of hay fever in the UK.

Animals

Cat (Fel d 1, Fel d 2, Fel d 4), dog (Can f 1, Can f 2, Can f 5), horse, rabbit, hamster, guinea pig, cow, and other animal danders, epithelia, and saliva proteins.

House Dust Mites & Storage Mites

Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis, and storage mites — a common hidden trigger in homes throughout the year.

Foods

Peanut, all major tree nuts, wheat, gluten, cow's milk, egg, soy, fish, shellfish, sesame, celery, mustard, kiwi, banana, apple, peach, cherry, stone fruits, and many more.

Moulds & Yeasts

Alternaria alternata, Cladosporium herbarum, Aspergillus fumigatus, Penicillium notatum, Candida albicans, and additional environmental moulds and yeasts.

Insect Venoms & Other Triggers

Bee venom (Api m 1), wasp venom (Ves v 1, Ves v 5), cockroach, mosquito, ants, and latex (Hev b allergens) — critical for identifying potentially life-threatening sensitivities.

Molecular Allergens — 218 Specific Components

The unique and defining feature of ALEX3. Molecular allergens are specific proteins within whole allergens. Testing at molecular level identifies cross-reactions and assesses allergy severity.

Occupational & Other Allergens

Various occupational allergens and additional clinically relevant triggers that standard panels do not include.

ALEX3 covers more than 95% of major problem-causing allergens — all confirmed in a single blood draw at our Surbiton clinic.

What Makes Molecular Allergen Testing So Important?

Most allergy tests check whether you react to a whole food or substance — for example, whether you have an IgE response to apple. This is a useful starting point, but it misses a critical piece of information: which specific protein within the apple is triggering your immune system?

The ALEX3 goes further by identifying the individual molecular components that make up each allergen. For example, within apple there are several different molecular allergens — Mal d 1, Mal d 2, Mal d 3, and Mal d 4. Each has a very different clinical significance. A reaction to Mal d 1 is often associated with oral allergy syndrome — a mild reaction commonly seen in people who are also allergic to birch pollen. A reaction to Mal d 3, however, is associated with a much higher risk of systemic reactions. Knowing the difference allows your clinician to give you appropriate, targeted advice rather than simply telling you to “avoid all apples.”

Molecular allergen testing also identifies cross-reactive triggers — situations where the same protein molecule is found across multiple different foods or pollens. This explains why some people react to apparently unrelated foods — it is often the same molecular component causing the response. Without molecular testing, these connections are invisible.

Finally, molecular allergen profiling can help identify whether a patient is a candidate for Allergen Immunotherapy (AIT) — a treatment that can progressively train your immune system to tolerate the trigger allergen. This is a potential pathway to long-term relief rather than simply managing symptoms indefinitely.

The Science Behind the ALEX3 Test

How the Test Works

The ALEX3 Allergy Xplorer is an ELISA-based IgE multiplex assay. When you are exposed to an allergen that your immune system has been sensitised to, your body produces a specific antibody called Immunoglobulin E, or IgE. These IgE antibodies are only found in the serum of your blood — not in saliva or hair — which is why a blood test is the only scientifically valid method for detecting true IgE-mediated allergies.

In practical terms, the ALEX3 test measures two things simultaneously: your total IgE level (the overall amount of allergy antibody in your blood) and your specific IgE levels against each of the 300 individual allergens in the panel. This dual measurement provides a highly detailed picture of your allergic profile, indicating not only which allergens you are sensitised to, but to what degree — information that is clinically essential for risk assessment and treatment planning.

Why ALEX3 Has a Low False Positive Rate

Non-specific IgE antibodies against Cross-Reactive Carbohydrate Determinants (CCDs) are automatically blocked in the ALEX3 test. CCDs are carbohydrate structures found in many foods and pollens that can cause misleading positive results in other allergy tests. By neutralising CCD interference, the ALEX3 delivers high specificity and substantially reduces the risk of false positive results — a common problem with less sophisticated allergy panels.

Approved & Validated

ALEX3 is clinically and scientifically validated, approved for use in NHS Allergist practice, and used to guide Allergen Specific Immunotherapy (AIT) treatment decisions — the most credentialled allergy test available in the UK.

Safe & Non-Invasive

This is a standard venous blood draw from your arm — identical to any routine blood test. You are not exposed to any allergens during the test. It is completely safe for patients with a history of anaphylaxis.

What Our Patients Say

★★★★★

“I had suffered with unexplained digestive symptoms and skin reactions for years. My GP had done some basic tests but nothing conclusive came back. I decided to try the ALEX3 at Lambert Medical Practice and it was genuinely life-changing. The report identified several molecular allergens I had never even heard of, and suddenly it all made sense. The nurse was brilliant, the clinic was spotless, and I had my results the very next morning. Would recommend to anyone who has been going round in circles trying to get answers.”

Sarah T., Kingston upon Thames

★★★★★

“I was sceptical at first — I had done one of those home kits a couple of years ago and found the results confusing and unhelpful. The ALEX3 at Lambert’s was a completely different experience. Three hundred allergens in one test, a proper nurse taking the blood, and a clear, detailed report that actually explained what I was reacting to and why. The molecular allergen section was particularly enlightening — it explained cross-reactions I had been experiencing for years. Brilliant service.”

James R., Wimbledon

★★★★★

“My teenage son had been struggling with hay fever and what we thought might be a food allergy for a long time. The ALEX3 test gave us a complete picture in one go. The clinic is professional and welcoming, the process was quick and painless, and the results arrived the same day. We were then able to discuss everything with our GP armed with a proper clinical report. It saved us months of guessing and multiple further appointments. Absolutely worth every penny.”

Your Questions Answered

The ALEX3 Allergy Xplorer is the most comprehensive specific IgE allergy test currently available. It screens your blood against 300 allergens in a single test — including 218 molecular allergens and 82 traditional allergen extracts — across 80 allergen families and 145 allergen sources. This covers more than 95% of major problem-causing allergens including foods, pollens, animals, house dust mites, moulds, insect venoms, latex, and occupational allergens.

Your blood sample is taken by our qualified phlebotomy nurse via a standard venous blood draw from your arm — the same method used for any routine blood test at your GP or hospital. This takes under 5 minutes and is performed in our CQC registered clinical facility. A venous draw produces a superior quality sample compared to finger-prick home kits, contributing to more accurate results.

No — this is one of the key advantages of the ALEX3. Unlike many other allergy tests, the ALEX3 is not affected by antihistamine use. You can continue all your normal medications, including antihistamines, before and during sample collection. There is no need to suffer through your symptoms before attending your appointment.

We aim to issue your full 300-allergen results report the same day your sample is received at our laboratory before 11am. If your sample arrives after 11am, results will typically be issued the following working day. Results are emailed as a detailed PDF report. Standard turnaround is same day or next working day — considerably faster than many alternative services.

Your report lists all 300 allergens tested with your specific IgE levels for each. It includes a summary page to assist in interpreting the results, identifies any detected sensitivities, grades the severity of IgE responses, and highlights any molecular cross-reactive allergens. We strongly recommend reviewing the report with your GP or an Allergist if any sensitivities are identified — and we can facilitate this through our in-house GP service.

A molecular allergen is a specific protein component found within a whole allergen. For example, apple contains several molecular allergens — Mal d 1, Mal d 2, Mal d 3, and Mal d 4 — each with different clinical implications. Identifying which molecule is triggering your response helps determine allergy severity, explains cross-reactions between seemingly unrelated foods, enables targeted dietary guidance rather than unnecessary elimination, and can indicate whether Allergen Immunotherapy may be appropriate.

The ALEX3 is a specific IgE blood test, which means it detects true IgE-mediated allergic reactions. Food intolerances (such as lactose intolerance) are not IgE-mediated and would not be detected by this test. If you suspect you have a food intolerance rather than a true allergy, we offer separate intolerance testing. If you are unsure whether your symptoms are allergy or intolerance-related, please call us on 0208 133 5694 and we can advise which test is most appropriate.

Yes — completely. This is a blood test only. You are not exposed to any allergens during the test itself. The nurse simply takes a standard blood sample from your arm. The test is entirely safe for patients with a history of anaphylaxis or severe allergic reactions. In fact, identifying your specific allergens is particularly important if you have had a severe reaction, as it can inform emergency planning and risk assessment.

Yes. The test is suitable for young children and adults of any age. Only a small blood sample is required. Testing babies under 6 months of age is not advisable as their immune systems are still developing. Babies aged 6–18 months should be assessed by an Allergist before testing to confirm it is appropriate. For older children, the test is straightforward and the small volume of blood required makes it a preferred option.

Yes — £295 is the complete, all-inclusive price. It covers your nurse consultation and blood draw in our CQC registered clinic, full ALEX3 laboratory analysis against 300 allergens, and your detailed 300-allergen results report. There are no hidden booking fees, no nurse consultation surcharges, no laboratory add-ons, and no results delivery charges. £295 is the total amount you will pay.

No referral is required. This is a private service and you can book directly online or by calling 0208 133 5694. However, if an allergy is detected in your results, we strongly recommend discussing the report with your GP or a specialist Allergist. If you would like a GP appointment to review your results as part of your care, our in-house GP service is available and included in the Complete Allergy Package.

No special preparation is required. You do not need to fast, stop medications, or change your diet beforehand. Simply wear clothing that allows easy access to your upper arm (short sleeves or sleeves that roll up easily), stay well-hydrated on the day as this makes the blood draw easier, and bring a form of photo ID. That is all. The appointment will take approximately 15 minutes in total.

A skin prick test typically checks 10–20 allergens by applying small amounts of allergen extract to the skin and pricking through them. It requires you to stop taking antihistamines for several days beforehand and carries a small risk of localised reaction. The ALEX3, by contrast, is a blood test that screens 300 allergens — including 218 molecular allergens — from a single sample. It does not require antihistamine cessation, carries no risk of allergic reaction during the test, automatically blocks CCD false positives, and provides molecular-level detail that skin prick testing cannot. For comprehensive allergy profiling, the ALEX3 is significantly more thorough.

Absolutely. The ALEX3 tests for a comprehensive range of grass, tree, and weed pollens — the primary triggers of hay fever in the UK. It identifies the specific molecular pollen allergens you react to, which can explain why your symptoms appear at certain times of year and guide targeted treatment, including whether you may be a suitable candidate for pollen immunotherapy (desensitisation).

The ALEX3 is not routinely available on the NHS. NHS allergy testing typically involves skin prick tests or individual specific IgE blood tests against a limited panel of allergens. The ALEX3 is a private test offered at Lambert Medical Practice for £295 all-inclusive. Many of our patients choose the ALEX3 because it provides a far more comprehensive allergy profile in a single appointment, without the long NHS waiting times.

Standard allergy tests check whether you react to a whole allergen extract — for example, “peanut” or “cat.” Molecular allergy testing goes deeper by identifying the specific protein components within each allergen that trigger your immune response. This is clinically important because different molecular components carry different risk levels — some indicate mild oral allergy syndrome, while others indicate a risk of severe systemic reactions. Molecular testing also reveals cross-reactive allergens, explaining why you may react to seemingly unrelated foods. The ALEX3 includes 218 molecular allergens, making it the most comprehensive molecular allergy panel available in the UK.

Yes. The ALEX3 produces a clinical-grade report that is fully recognised by GPs and NHS Allergists. Many of our patients take their results to their GP or consultant to inform ongoing treatment decisions, including referrals for Allergen Immunotherapy. The detailed molecular allergen data in the report provides the same level of information that NHS Allergists use in specialist practice.

Home allergy kits typically test 20–100 allergens using a finger-prick blood sample collected at home. While convenient, the sample quality from a finger prick is generally inferior to a professional venous draw, which can affect accuracy. Home kits do not include molecular allergen testing, do not block CCD false positives, and do not offer the clinical support of a CQC registered medical facility. The ALEX3 at Lambert Medical Practice tests 300 allergens including 218 molecular components, uses a professional nurse-drawn venous sample, and provides same-day or next-day results — significantly more comprehensive and clinically reliable.
