Allergy Tests in London – Review by Consultant Allergist
At London Allergy and Immunology Centre we provide allergy tests in London as well as UK wide in England Scotland Wales and Northern Ireland.
Allergy testing in the UK can help your doctor to identify sensitisation to specific allergens. There are several types of allergic reactions, but some reactions that look like allergies can be of a non allergic nature. Urticaria and angioedema (rashes and swellings) can be of allergic and non allergic causes. Sometimes there is no need to do tests for an experienced allergy consultant and in some types of allergy food and symptom diary and good history can give required information for the doctor to make a diagnosis.
In the allergy testing clinic you will get the opinion of our allergy consultants and will be able to choose the best allergy tests that will give maximum information to make a correct diagnosis and prescribe treatment.
In the London Allergy and Immunology Centre an allergy test in London is done following or during a consultation with allergy specialists, and even in case of remote allergy test ISAC we will get full medical history via an on-line questionnaire that will help our allergy consultants to interpret results (consultant’s review is included in the test’s price when you have remote testing).
We have facilities to arrange appointments following remote testing and we will always write to your GP with the results, so the continuity of care and link with NHS primary care services is preserved.
Allergy Testing in the UK
RAST Specific IgE test, sIgE blood allergy test is testing sensitisation to a single allergen of choice (milk, wheat, gluten, cat, dog, grass, moulds, birch, penicillin etc) There are more that 400 allergy tests to choose from.
Immunocap ISAC Specific IgE test, sIgE blood allergy test most comprehensive screening sIgE detection to 112 allergenic components we can do this test remotely when the sample is sent by the patient from any place in the UK straight to the lab in the post in a special container.
Patch test or epicutaneous test for delayed skin reaction metals chemical sensitivity, reactions to make-up, cosmetics – allergic contact dermatitis. This test is done on Saturday with reading of results on Monday and Tuesday (48h, 72h and 96h)
Food and symptom diary: Elimination diet with reintroduction for delayed reaction in atopic dermatitis, eczema and other skin conditions and where food might be linked to exacerbations. Our special food-symptoms diary is used for this test. It is reviewed and supervised by allergy consultant.
Skin prick allergy test is the test that can be done only during consultation. It takes no more than 15 minuets to get results and sometimes modification of the test Prick to Prick test is used. You can bring food in individual plastic bags, or plants that you suspect being allergic to and our allergy consultant will arrange this test.
Intra-dermal tests are done as a part of drug allergy challenge testing or some other tests where sterile allergen solution is available. It usually follows skin prick test and gives exposure to a higher volume of allergen when it is injected in the upper layer of the skin.
Provocation tests: Ocular conjunctival, Nasal provocation tests are used to confirm allergy to a specific allergen.
Food provocation test (oral food challenge) is used to confirm allergy to a specific food, find out the amount of allergen that can trigger reaction and severity of the reaction. It is done in hospital under careful supervision of trained staff and with resuscitation equipment. This test should be never be used at home.
Drug allergen challenge is an important test where there is a doubt in diagnosis or it is not know which drug caused the reaction in the past. It is also done in the hospital under careful supervision of resuscitation team. This test should be never tried at home.

Allergy testing with precision. Sightly higher costs comparing to standard allergy test but very detailed
The term Allergen component is used for products based on molecular allergens purified from either their natural source (native) or biotechnologically produced as recombinant proteins.
By using tests for single allergenic components as a complement to more traditional IgE antibody tests, further clinically relevant information can be gained.
ImmunoCAP Allergen components are useful tools when investigating and explaining allergic reactions more in detail and to determine if they are caused by cross-reacting IgE antibodies to different allergens. ImmunoCAP® Allergen Components – Allergen components
