Allergy Tests Remotely and in the Laboratory
Consultations with Harley Street Allergy Specialists
Food Allergy and Respiratory Allergy?
Do you experience unexplained rashes, swelling, breathing difficulties, or digestive discomfort after eating certain foods? Or perhaps you often suffer from a blocked or runny nose, itchy eyes, or a tingling sensation in your mouth when eating fruits or vegetables?
A private IgE allergy blood test can help to identify whether the immune system is reacting to specific food or environmental allergens. By pinpointing the exact triggers — whether they are in the diet or the air we breathe — informed steps can be taken to manage symptoms and improve quality of life.
Taking control of health is possible with an accurate, and convenient allergy test.
Introducing the New ALEX³ Allergy Test
We are pleased to offer the latest generation of molecular allergy testing — ALEX³. This comprehensive screening test analyses over 300 allergen extracts and molecular components from a simple finger-prick blood sample, making it one of the most advanced IgE allergy panels available worldwide. ALEX³ detects both food and respiratory allergens and helps identify cross-reactivities (such as pollen–food syndrome) that may explain complex allergy symptoms. The test provides a clear, detailed report highlighting your individual sensitisation profile, supporting targeted management and dietary advice. ALEX³ can be done remotely at home or in our clinic during appointmetns with allergy consultants in London with results typically available within two weeks.
Individual Allergy Test
For those with a specific allergen in mind, we also offer the option to test for an individual allergen. This tailored approach provides maximum flexibility. All testing—whether you select a single allergen or a comprehensive panel—can be done conveniently from home using a simple finger-prick kit (where one tiny blood sample can test for up to three individual allergens) or by visiting our clinic in London for consultation and allergy testing with our consultants.
View all individual Allergy Tests either can be done at home from a finger prick (up to 3 from one blood sample) remotely or by visiting our laboratory in London.
Stool Test for Helicobacter pylori
Helicobacter pylori (H. pylori) is a common bacterial infection of the stomach, usually spread through contact with contaminated hands. It is a persistent infection that will not go away by itself. The usual symptoms include heartburn, acid reflux, a burning or pulling pain in the stomach (especially at night), or a sour taste in the mouth. In some long-standing cases, symptoms may become less noticeable, but the infection can still be active and may cause unexplained hives, rashes, or swelling.
Infection with H. pylori can activate mast cells (see reference below), which may make allergic reactions more severe. It can also be an underlying factor in some patients with urticaria (hives) or angioedema (swelling). If your test is positive, your GP should arrange treatment following the NICE protocol, which includes several antibiotics and acid-suppressing medication taken together.
This non-invasive test is done by collecting a small stool sample at home and sending it to our laboratory for analysis.
Note: Please wait at least two weeks after stopping antibiotics or proton pump inhibitors (such as esomeprazole, omeprazole, lansoprazole, or pantoprazole) before collecting your sample, as these medicines can cause false-negative results.

Blood Samples
Unlike other tests that use unproven methods like hair samples or bio-rhythms, we specialise in scientifically-validated IgE blood testing for food and respiratory allergies. Our testing is backed by clinical research, peer-reviewed publications, and appropriate laboratory accreditation.
A home blood-testing kit is sent to you by post. It is used to collect a small sample from a finger-prick for our major screening test, ALEX³, which covers a set selection of over 300 allergens.
Alternatively, you can select up to three individual allergy tests from our website per order.
If testing is required for more than three individual allergens, a larger volume sample will need to be collected by a nurse at our laboratory or you can place several separate orders if you want to have it done remotely.
How it Works
You are in control of selecting the test that best suits your needs. Should you require assistance in making your choice, we offer the option to book a consultation with one of our allergy and immunology consultants, available via video link or in person for an additional fee.
We offer two main testing paths. You can choose our comprehensive ALEX³ macro-screening test, which analyses over 300 allergens for £467. Alternatively, you can select individual allergen tests for £42 per allergen. Laboratory handling fee of £58 is applied to each order.
Once you have ordered, a straightforward home-testing kit will be dispatched to your address. The kit is designed for a simple finger-prick blood collection.
You can discuss results and agree treatment plan with our allergy specialists for an additional fee.

Order Process
Once you have paid the fee via our secure Worldpay system, your testing kit will be sent out with full instructions. If you are not comfortable providing your own sample, please seek the assistance of a medical professional, particularly if the test is for a child.
For those based in London, we provide an alternative: you can visit our laboratory to have a blood sample taken by a nurse (in such case just contact our team by email and don’t purchase tests on the website).

Warning!
Do not be fooled by the widely available IgG tests online for food intolerance. There is no need to change your diet if IgG antibodies to food are detected. IgG antibodies do NOT indicate an allergy or intolerance to a specific food. IgG antibodies to food are formed in all healthy people as a part of the digestion process. There is no specific screening test for intolerance at present. In our department we can also offer tests for Lactose and Gluten intolerances.
Our Customers
A world renowned allergy and Immunology specialist who provides outstanding advice and guidance for parents going through heart ache resulting from multiple food allergies. His calm and educational approach has left us close to tears after finally having answers to so many questions. My son has dozens of food and environmental sensitivities, intolerances and a number of life threatening food allergies. He also has numerous environmental issues which seemed near impossible to pinpoint. In my opinion the London Allergy and Immunology Centre is an exceptional centre of excellence.
