How The Food Intolerance Test Works

How the Food Intolerance Test Works

Over 45% of the population react adversely to foods that they eat, which whilst not life threatening, can have a massive impact on someone’s quality of work and home life. Food intolerance is a condition with a range of symptoms including gut symptoms, bloating, headaches, migraines, low mood, fatigue, weight gain and skin problems.
The way that food can affect our everyday life is often difficult to explain and it is common for people to try and eliminate foods from their diet to help themselves feel better. Often they don’t know which foods to try and eliminate and have to guess. Many people don’t know that identifying food intolerances can be an important element of optimising health and wellbeing.

Here in the clinic we use the Lorisian Food Intolerance Testing System. We chose this system because Lorisian has over 30 years’ experience, specialising in laboratory tests that measure food triggers (food-specific IgG antibodies). The results offer a fast track or starting point for an elimination diet. The tests are aimed at those that may have food intolerances, and those who want to optimise their diets by avoiding any foods that they are reacting to. Our aim in the clinic is to promote wellbeing within the pressures of a modern lifestyle. There are 3 testing options available with reactions to 50, 100 or 150 Plus different food ingredients tested.

How The Test Works

Lorisian food intolerance tests use a very simple finger prick blood collection wand system. It is a quick and easy way to collect a blood sample. The sample is then sent back to the Lorisian Laboratory, where it is tested and analysed for IgG antibody reactions.

At The Laboratory

When the sample of blood is received at the laboratory, the following steps are taken with each sample:
• The sample is processed with the utmost care and attention and all sample information is stored on a secure IT system
• Each sample is given its own unique tracking number to allow us to track it through the testing process
• The blood sample is removed from the wand and prepared for testing
• The laboratory uses ELISA technology (enzyme linked immune-sorbet assay) to detect food-specific IgG antibodies in your blood. The ELISA method is used extensively in hospital laboratories. This technique has been shown to be highly reproducible in measuring antibodies of clinical importance. The test is unique to Lorisian and the parent company has been providing diagnostic testing since 1982
• They then check the sample at 7 key stages through the laboratory process before sending out the final result
• Once your sample has been tested it is disposed of in a secure manner and the information is stored within our secure data storage system
• Each sample tested has customised results pack assembled which are available for the client.

The Results

The results are then sent back to the clinic, where you will be contacted to make an appointment to come in for a one to one nutritional consultation, to discuss the results and put a food plan in place. An easy to understand colour coded results sheet shows you the foods that you need to avoid, limit and enjoy. Foods in the red zone indicate that there is a raised IgG antibody levels to these foods and you should try eliminating them completely from your diet. Foods in the yellow zone indicate a borderline reaction to these foods and you may or may not benefit by limiting their consumption. Food in the green zone indicates foods that can be eaten without restriction.

About Lorisian

Lorisian specialises in offering laboratory tests that measure food-specific IgG antibodies which are sometimes referred to as food intolerances. Lorisian was set up in 1982 and has designed, developed and manufactured their food-specific IgG enzyme linked immunosorbent assay (ELISA) test since 1998.

Their food-specific IgG method has had more papers published about its performance than other food food-specific IgG tests on the market.

The studies include two independent randomised controlled trials; including a unique trial in IBS. In addition the largest survey of its kind, commissioned by the UK medical charity Allergy UK, with over 5,000 participants, 76% of which reported moderate to high benefit after using the service.
