Do Food Intolerance Tests Work?

PR Newswire YORK, England, November 29, 2012

YORK, England, November 29, 2012 /PRNewswire/ --

There are now many different diagnostic tests available outside of the conventional medical system (the NHS in the UK). These include many different tests for food intolerance including vega testing, kinesiology, hair "body field analysis" testing, cytotoxic and live blood testing. The growing market is driven by increasing personal interest in health, clinical need as many chronic conditions are not being treated, limitations of the conventional medical system and direct customer demand. Doctors and medical practitioners can be justified in dismissing test results that originate from services such as 'mail order laboratory testing services', as there is currently no way for them to distinguish between those results which have an evidence base with clinical data, and those that claim results without any real evidence.

How are individuals meant to tell the difference between the plethora of diagnostic tests that are available to them? How can they tell those based on good science and those that have no basis is science? It is a difficult task. Consumers should be able to take more responsibility, and have access to tests that can empower them, not potentially damage them. In order to show that results from a specific diagnostic test are meaningful, and can be interpreted and acted upon accurately and effectively, it is absolutely essential that food intolerance tests undergo rigorous evaluation to make sure that they perform well enough to provide accurate and reproducible information.

For the first time, guidance has been issued to help people ask the right questions of diagnostic test providers. The checklist has been welcomed by food intolerance test suppliers YorkTest Laboratories. Dr Gill Hart, Scientific Director at YorkTest Laboratories commented saying: "The food intolerance testing industry has been given a bad name by suppliers of tests that have absolutely no basis in science. YorkTest have been offering food intolerance testing services for over 30 years and have helped many thousands of people over the years find relief from symptoms such as IBS, bloating, migraines, fatigues, itchy skin , low mood and weight gain. Our clinical data speaks for itself and we are pleased to now see measures being put in place that can distinguish our services from those that do not meet the criteria on the checklist."

The checklist, originally published in the journal Nutrition Practitioner, includes the following pointers:-

Check whether the test supplier is audited annually by the UK Health Authority (the MHRA) or is CPA (Clinical Pathology Accredited). Also ensure that the tests and sample collection methods have been CE marked. The supplier should be able to provide their certificates. Check that the test is accurate (what evidence exists?); has the test been referenced or calibrated against a recognised international standard? If no 'gold standard reference point' exists then clinical studies to show effectiveness must be provided. Look out for real case studies and testimonials to show that the test works in practice, and can be interpreted correctly. Talk to other people that have used the test and find out about their experience. Check that the supplier has evidence that the sample (for example a blood sample) is stable during transport to the laboratory. Also ask for the supplier to provide reproducibility data.

Dr Gill Hart continued: "Being able to question the suppliers of diagnostic tests will help people to feel confident to really tackle their food intolerance symptoms, knowing that their targeted action is based on good sound information."
