Types of Testing For Food Intolerance

Many people write to us, asking for help - having had extensive clinical testing for  food intolerance. However when they follow the guidelines - the symptoms persist.

How does this happen? Unfortunately clinical testing like breath testing and single blood tests are no longer seen as completely reliable. The trusted Journal Method however always gives fast accurate answers.

Clinical Tests from Your Doctor

Your medical doctor (General Practitioner) may use:

  • Several kinds of blood tests
  • Hydrogen breath testing*
  • Allergy testing (e.g. by skin pinprick method)
  • Gastroscopy (tube guided into stomach while under anaesthetic)
  • Intestinal biopsy (small tissue sample taken under anaesthetic)
  • Stool (faecal) analysis
  • Skin sample analysis (e.g. with flaking skin infections)
  • Genital swab (e.g. for fungal conditions)

*No longer practised by many doctors who cite unreliability

However - you may need more than one test. In fact the doctor usually orders a series of tests - because one can contradict the other - and a full picture must be built up with a series of tests, which can take many weeks.


Naturopath - or Alternative Practitioner

A naturopath or alternative medicine practitioner may use:

  • Iridology (diagnosis by looking into the iris of the eyes)
  • Homeopathy - examination of eyes, skin, tongue and pulses
  • Vega testing (now discredited by many professionals)
  • Reflexology - pressing on soles of feet
  • Other methods

While different people get different results, most of these tests only give an indication of food intolerance. Almost all consultations come to the same point: the patient is advised to do some kind of elimination diet - using a Journal - to confirm the test results. 

We have found the best results come by using a journal – and with moderation … that is a diet which allows some favourites while greatly reducing the level of toxins in the blood . . . find out more at foodintol® LoTox Living
