IgG Food intolerance Testing - Brunel Health
Food intolerance can bring a wide range of symptoms including:-
- gut symptoms
- low mood
- weight gain
- skin problems.
Symptoms of food intolerance can devleop at any time, sometimes following a bout of illness, stress or even a course of antibiotics. Symptoms can take up to 72 hours to appear after eating the trigger food or group of foods often making it difficult to connect the dots.
Using easy finger prick and wand blood testing, the Brunel IgG Food Intolerance tests grades your reaction to 134 different foods and drink.
On average people who suffer from food intolerances usually have between 4 and 8 trigger foods. Many people suffer for years, having formed a coping mechanism to deal with the symptoms but being unable to enjoy a normal work and home life. Many people don’t realise that there are simple steps to take that could resolve their condition.
A recent study has shown that those who eliminated trigger foods based on food-specific IgG test results had reductions in weight, body mass index, waist and hip circumference and improvements in all indicators of quality of life that were measured.

Further small studies have suggested benefits in those who suffer from migraines, asthma and even Crohn's disease.

The Brunel Laboratory detects food intolerances by measuring IgG antibody reactions using the ELISA method, a globally established technique for laboratory analysis that is over 40 years old and universally accepted as reliable and trustworthy. The Brunel service is based upon testing for IgG antibodies, and the assertion that a positive result indicates a trigger food that causes an inflammatory response leading to a symptom.
Your inflammatory response is then graded according to its severity allowing food intolerances to be identified and profiled. A 30 minute telephone or online consultation is included with this test, as accurate interpretation is important to avoid any nutritional deficiencies that can arise if whole food groups are eliminated.
Frequently Asked Questions
What is the difference between food allergy & an intolerance?
The term ‘food intolerance’ and ‘food allergy’ are often confused and are two very different things. Genuine food allergy is relatively rare. Only about 2% of the adult population are affected. A food allergy is a swift response by the body’s immune system to a specific food. In this type of reaction, the body’s immune system mistakes a food for an ‘invader’ which often results in a rapid allergic reaction often within minutes, but generally within a maximum of two hours. This type of allergic reaction is commonly associated reactions to peanuts, tree nuts, milk, eggs and seafood.Food intolerance is quite different to food allergy and whilst the symptoms can impact the person’s quality of life they are not life threatening.
How is the sample taken?
The test kit is delivered via the post, there is no need to wait home as your test kit can fit through the letterbox. The test is a simple finger prick and wand collection with clear instructions within your test kit and a video to watch online for further information.
Once you have collected your sample it should be retuned as per instructions in the pre-paid envelope. Your results should be woth your therapist within 5 working days from the laboratory receiving your sample.
