Welcome to Lorisian

We're an expert in food intolerance testing. It is thought that over 45% of the population react adversely to foods that they eat. Whilst the effects may not be life threatening, resulting symptoms can have a massive impact on someone’s quality of work and home life. Here's what defines the high-quality service we offer to every customer that works with us.







Our Tests

Our aim is to promote wellbeing for those dealing with the pressures of a modern lifestyle. We have many testing options available to suit your client’s budgets, symptoms and dietary preferences. We also offer the UK’s only finger-prick homocysteine test on the market.

Food intolerance

Our laboratory analyses IgG antibody reactions to up to 208 food and drink ingredients. Identify your clients’ personal trigger foods and optimise their diet with food intolerance† testing.


Discover your clients’ homocysteine levels and help make improvements to their wellbeing. A high homocysteine level has been implicated in the development of heart disease, Alzheimers, dementia and infertility.


The Lorisian LiverCheck test is a simple and convenient home-to-laboratory test, which delivers reliable results within just 10 days.

What our customers say

“I’m extremely pleased with the test and only wish I’d known about it years ago... The biggest change is not being in pain or severe discomfort all the time. I suffer a great deal less than I use to which means I’m not worrying every time I have a meal or a bite to eat, and I can get on with my life."

Katie, 26 Digestive discomfort

"Had I known this information when I started out in professional rugby, it would have undoubtedly changed my diet, increased my self-awareness and most importantly improved my performance!"

Rob Vickerman Migraines

“Within just a few days of cutting out the foods I had lost 4lbs and felt less tired and lethargic.“
