Allergy Blood Tests
Private allergy blood tests that measure specific IgE to show what your immune system is sensitised to. Test a single suspected trigger, or screen a wide range at once with the ALEX Allergy Explorer. Every result is reviewed by a GMC-registered doctor and explained against your symptoms, because a number only matters in the context of how you actually react.

An allergy blood test measures specific IgE, the antibody your body makes towards a particular allergen. It is a good option when a skin-prick test is not suitable, for example if you have eczema, take antihistamines, or have had a strong reaction before. You can test a single suspected trigger or screen broadly. These are the allergen groups most often checked:
This is the most important thing to understand about allergy blood tests, and the reason a doctor reviews every result. A positive specific IgE means you are sensitised, your immune system recognises that allergen. It does not by itself confirm that the allergen causes your symptoms, and a negative result does not always rule an allergy out. The value of the test is in a clinician reading it alongside your history, deciding what is relevant, and agreeing what to do next.
The doctor matches your IgE results to the symptoms you actually experience, separates a meaningful trigger from a harmless sensitisation, and advises on avoidance, an action plan, or referral to an allergy specialist where appropriate. You get clarity and a plan, not just a list of numbers.
A single blood test that measures specific IgE to a wide range of allergens and allergen components at once. Ideal when symptoms have several possible triggers, or when triggers are unclear and you would rather screen broadly than one allergen at a time. Read more about the ALEX Allergy Explorer.
Specific IgE to one chosen allergen, when you already have a clear suspected trigger such as a particular pollen, food or animal.
Measures your overall IgE level, which can support the picture in conditions such as eczema or asthma and help the doctor interpret allergy symptoms.
An Immunoglobulins test (IgA, IgG, IgM) is also available at £129 (£168 all-in). This assesses overall immune function rather than allergy. One £39 administration fee covers your whole visit, however many tests you book, charged once per visit and never per test.
A skin-prick test and a blood test look at the same thing, an IgE response, in different ways. A blood test does not depend on a skin reaction, so it is the better choice when skin testing is not suitable: if you have a skin condition such as eczema or dermatographism, if you take antihistamines or other medicines that blunt skin testing, if a skin test would be hard to do, or if you have had a severe reaction before and prefer a sample taken from the arm. The doctor will tell you which approach fits your situation, and can refer you for skin testing or specialist allergy assessment if that is the better route.
Online, in person, or added during a GP consultation. A GMC-registered doctor reviews your request and helps choose the right test.
An experienced practitioner takes your sample in-clinic, usually 15 to 30 minutes. No fasting needed.
Your sample is processed by an accredited UK pathology laboratory using validated IgE assays.
Most results within 2 to 5 working days, interpreted against your symptoms, with a clear plan sent securely to your email.
Consider an allergy blood test if you have recurring sneezing, a runny or blocked nose, itchy or watering eyes, hives or itching, or symptoms after eating that you cannot pin to a clear trigger. It is also useful if you have eczema, asthma or sinus problems that may be linked to allergens, or if a skin-prick test is not suitable for you.
If you have signs of anaphylaxis, such as difficulty breathing, swelling of the face, lips, mouth or throat, a widespread rash with feeling faint, or a sudden severe reaction, this needs immediate help. Use an adrenaline auto-injector if you have one and call 999, or go to the nearest A&E. Do not wait for a blood test. An allergy blood test is for planned investigation, not for an active or recent severe reaction.
The NHS provides comprehensive allergy care, through your GP and, for complex or severe cases, specialist allergy clinics, and that pathway remains the right route for many people, particularly anyone who has had a severe reaction. KONCEPT® is designed to complement, not replace, that care. It makes specific IgE and the ALEX Allergy Explorer easy to access directly, without referral, with a doctor to interpret the result against your history. With your written consent we share a clinical summary with your NHS GP so your care stays joined up, and we refer on to specialist allergy services where that is the right next step.

An allergy blood test measures specific IgE, the antibody your immune system makes towards a particular allergen. A higher level means your body is sensitised to that allergen. We offer a single allergen test for a chosen trigger, a Total IgE test for an overall picture, and the ALEX Allergy Explorer, which checks a wide range of allergens in one sample. Every result is reviewed by a GMC-registered doctor who explains it against your symptoms.
Not on its own. A positive specific IgE shows sensitisation, meaning your immune system recognises that allergen, but sensitisation is not the same as a clinical allergy. Whether an allergen actually causes your symptoms is judged by a doctor alongside your history. Equally, a negative result does not always rule an allergy out. This is exactly why the result is interpreted by a clinician rather than read as a simple yes or no.
They test the same thing in different ways. A skin-prick test looks at a reaction on the skin, while a blood test measures specific IgE in a blood sample. A blood test is useful when skin testing is not suitable, for example if you have a skin condition such as eczema, take antihistamines or other medicines that affect skin testing, or have had a severe reaction before. The doctor can advise which approach fits your situation.
Common testable allergens include grass and tree pollens, house dust mite, pet and animal dander, moulds, foods such as nuts, milk, egg, wheat and shellfish, latex, and insect venom such as bee and wasp. You can test a single suspected trigger, or use the ALEX Allergy Explorer to screen a wide range at once. The doctor helps choose based on your symptoms and history.
The ALEX Allergy Explorer is a single blood test that measures specific IgE to a wide range of allergens and allergen components at once. It is useful when symptoms have several possible triggers, when triggers are unclear, or when you would rather screen broadly than test one allergen at a time. As with any IgE test, the results show sensitisation and are interpreted by a doctor against your history.
No. We offer IgE-based allergy testing, which looks at true allergic sensitisation. We do not offer IgG food-intolerance tests, because they are not supported by current evidence and are not recommended by UK allergy specialists for diagnosing food intolerance. If you have symptoms after eating, a doctor can advise on a sensible, evidence-based way to investigate them.
Most results are returned within 2 to 5 working days, depending on the allergens tested. The outcome note is sent to your email, password-protected. The ALEX Allergy Explorer can take a little longer, and you will be told the expected time when you book.
No. You can book online, in person at the clinic, or add the test during a GP consultation at KONCEPT®. A GMC-registered doctor reviews each request for clinical suitability and helps choose the right test before your appointment is confirmed.
An Individual Allergen Test is 69 pounds, a Total IgE Test is 99 pounds, and the ALEX Allergy Explorer is 379 pounds. A single 39 pound administration fee covers your whole visit, charged once per visit and never per test. The all-in prices are therefore 108 pounds, 138 pounds and 418 pounds. If a GP review is recommended afterwards, that is a separate booking: your NHS GP at no NHS charge, or a KONCEPT GP consultation at 149 pounds.
Allergy testing is available on the NHS when clinically indicated, usually through a GP and, for complex cases, an allergy clinic, and the NHS pathway remains the right route for many people. KONCEPT® complements that by offering specific IgE and the ALEX Allergy Explorer directly, without referral, with a doctor to interpret the result against your history. With your written consent we share a clinical summary with your NHS GP so the result is added to your NHS record.
