Who are Lorisian?

Lorisian, via its parent company YorkTest, specialises in offering laboratory tests that measure food specific IgG antibodies – known as food intolerances.

Market leaders for over 30 years!

YorkTest Laboratories was set up in 1982 and has designed, developed and manufactured their food - specific IgG enzyme linked immunosorbent assay (ELISA) test since 1998. Lorisian results and test methods are overseen by our Medical and Scientific Directors

Lorisian offers 4 tests that offer different numbers of ingredients tested:

  1. Lorisian | 50 Analyses your IgG antibody reaction to 50 food ingredients
  2. Lorisian | 75 Analyses your IgG antibody reaction to 75 food ingredients
  3. Lorisian | 100 Analyses your IgG antibody reaction to 100 food ingredients
  4. Lorisian | 150 plus Analyses your IgG antibody reaction to more than 150 food ingredients

What are food intolerances?

There is a lot of confusion about the terms food intolerance and food allergy, and the differences between them. Many people think they have a food allergy when their symptoms can sometimes indicate food intolerance instead. Up to 45% of the population suffer from food intolerance* which, whilst not life threatening, can have a negative impact on many aspects of daily life.

When foods and drinks are digested the proteins within them are broken down into smaller fragments for easy absorption into the body. Larger fragments can pass through without breaking down, and sometimes the body reacts to them as invaders, attacking them using antibodies called Immunoglobulin (IgG).

This can cause inflammation and a wide range of symptoms including headaches, digestive problems, IBS, bloating, itchy skin, joint pain, weight gain and low mood to name a few. *According to the leading medical charity Allergy UK

How does Lorisian food intolerance tests work?

First of all a few drops of blood are taken using our simple finger prick blood collection wick system. Because the finger prick system is so easy to use, the sample can be taken anywhere – at your premises, at the clients’ home, at the gym etc.

The sample is then posted back to our laboratory (in a pre-paid envelope), tested and analysed for IgG antibody reactions to more than 150 food and drink ingredients. Clear colour coded test results and support pack are delivered back to you that explain your clients’ food and drink intolerances.

This allows you to discuss in detail recommended dietary and nutritional changes - a fast track to an elimination diet that optimises health and wellbeing.

What's the difference between Lorisian and other food intolerance test kits?

There are no international standards available for tests that measure food-specific IgG antibodies. The only way that a particular food specific IgG test can be shown to be valid is by carrying out clinical trials.

Our food-specific IgG method has had more scientific papers published about its performance than any other food intolerance test on the market.

The studies include two independent randomised controlled trials; including a unique trial in IBS. In addition the largest study of its kind, commissioned by the UK medical charity Allergy UK, with over 5,000 participants, 76% of which reported moderate to high benefit in their chronic ill health symptoms after using the service. This means that we can make claims about test accuracy and effectiveness using substantive evidence; something that other suppliers cannot do; there are many tests and programmes that are offered that do not have any published data available to show how they perform.

False positive results remain the biggest challenge for test providers. We use a proprietary formulation during the ELISA (enzyme linked immunosorbent assay) test manufacturing process in order to block non-specific binding (false positive results).

We can therefore provide the maximum benefit and support for your customers by accurately advising minimal dietary changes. We have data sets supporting a reproducibility of greater than 98%. This is achieved by using consistent and controlled manufacturing processes and operating procedures.

Reproducibility performance is supported with regular routine quality control checks and includes ELISA plate to plate checks and sample to sample data. Sample stability claims are also supported.

The results speak for themselves!

An Independent Customer Survey conducted by The University of York (2007), carried out on 5,286 people - the results were then divided into patient groups and the findings are summarised here.
