Food Allergy Testing & Food Intolerance Testing in London
Top 25 Food Allergy Moms – 2012
At the London Allergy and Immunology Centre we can provide food allergy testing in London. Below are the questions that our patients ask after severe reaction when food consumption is the suspected cause:
Was it an allergic reaction to food?
What exact food was it?
Is it going to happen again?
What food do I need to avoid?
We offer consultations in dermatology, adult allergy and immunology, and paediatric allergy and immunology.
If you require food allergy testing in London please include your age and a brief description of the problem. Your e-mail will be directed to the selected consultant.
We try to reply all e-mails and book appointments as soon as possible.
Once we receive the request the practice manager of your selected consultant will contact you with the details of your appointment.
We will reply to your e-mail request within one day and the waiting list to see our consultants is not more than 1 week.
We can give dietary advice after doing one or more of the following tests:
- Skin prick test with commercially available food extracts
- Prick to prick test with fresh or cooked food
- Challenge test with food in safe hospital environment
- Blood test Specific IgE to food (note not IgG)
- Biochip – molecular method of Specific IgE detection Immunocap ISAC
When the causing agent is found we will advice on dietary requirements and treatment in case of emergency.
Food allergy or Food intolerance?
When the patient experiences mild symptoms or the symptoms are not immediate it can be difficult to identify the cause. In many cases these causes are related to allergy and the tests outlined above can confirm this.
The primary task is to exclude likelihood of a life-threatening reaction!
If results for food allergy testing in London are negative, a close communication between the doctor and the patient with the help of dietary methods (food and symptom dairies followed by complex bio-chemical tests) can detect the condition known as intolerance, which is usually caused by an absence or low levels of enzyme’s that break down specific sugars in food.
We will take all your symptoms seriously, diagnose, and where permissible, treat the cause
We will try our best to get to the bottom of the of your problem
We will explain everything to you (no hidden charges and no “magic” supplements)
We use only traditional medical and scientific approaches.
Intolerance can be diagnosed by the exclusion of products one by one, with further reintroduction in a blinded manner, confirming absence and return of the symptoms.
Don’t be fooled with widely available IgG tests for food intolerance
There is no need to change your diet if IgG antibodies to food were detected
The presence of IgG antibodies does NOT indicate an allergy or intolerance to a specific food
IgG antibodies to food are formed in all healthy asymptomatic people as a part of the digestion process
There is no screening test for intolerance at present

Make sure you have your auto-injector with you at all times and it is up to date
If you have an EpiPen Please follow the link to set up an expiry date reminder to your e-mail or mobile phone.
One may also think about wearing an ID that can potentially save his/her life by giving information about a diagnosed condition to rescuers.
Food allergy and air travel
While no airline can guarantee the complete absence of peanuts or other allergens from a flight, the allergy policy of airlines varies widely between companies. Choose an airline that will accommodate your needs.
If your doctor prescribed an adrenaline (epinephrine) auto-injector make sure that it is in date and you have a letter from your doctor that will allow to take it on board the air-plane in hand luggage.
