FAQs
What’s included in my test?
The test includes one intolerance test, one nutritional deficiency test, and one metal test. Your intolerance test results include all items that have shown a score of 85% and higher. After completing thousands of tests, we now know that 85% is the turning point where symptoms begin to develop into an allergy/intolerance.
What should I do with my test results?
To increase your quality of life you should, over a period of 4–6 weeks, completely exclude the items your body is intolerant to. During this time your body will get the peace and quiet it needs in order to repair itself. After this period you can either take a new test to be sure your body is “ready” or, gradually and in small increments reintroduce the items to see if there is any reaction. As for the nutrients you may be missing, we recommend that you follow our dietary guidelines and make sure that your body gets the nutrients it needs to stay healthy and strong.
How do your tests compare to blood samples?
In addition to being less invasive and significantly cheaper, your last meal may affect the results of a blood sample, whereas a hair sample has the information stored for a longer period and reflects a wider time frame.
How do I take a hair sample?
The safest way to take a hair sample is by asking someone to help you. First, brush your hair upwards to get easy access to the hair roots and the back of your head. Hold a small amount of hair between your finger and thumb, and cut the hair as close to the scalp as possible (without pulling any blood). If you do not have someone who can help you, please use a mirror to avoid accidentally hurting yourself.
How do I submit my hair sample?
When your order is successfully completed, instructions will be sent to your email along with your receipt (i.e. we will not send test kits). Simply take 4–5 hair strands from your scalp, put them in an envelope along with a completed form (instructions are emailed post order).
My hair is dyed. Will this affect the results?
No, we test the composition of the hair sample, so the hair dye will not affect your test results.
How much hair do I need to submit?
Only a small amount; 5 individual strands. We don’t require clumps of hair.
What’s the difference between allergy, hypersensitivity, and intolerance?
There is quite a big difference between being allergic, intolerant, or hypersensitive to a substance however, the symptoms often resemble each other. For those who get ill from their diet, it may feel equally bad. The devil is known by many names, some might say. Our test results will shed a light on what intolerances you might have, in other words, which ingredients to avoid. An intolerance may pass after a period of time, while an allergy lasts for life.
Can children take the test?
Unfortunately, we don’t recommend the test for anyone below the age of 5. Younger children have not yet built up their tolerance levels, and this can give false results in the lab.
Can animals/pets take the test?
Yes, hey can. Pets can suffer from similar intolerances to humans. We offer a Pet Intolerance Test for cats and dogs with 60 checks for common pet food brands, in addition to environmental factors.
How do I purchase an intolerance test from you?
Tests can be easily ordered on our website. Should you have further questions, please don’t hesitate to email us.

I am so happy that I bought this test and at such a great priced too. I am thrilled and excited with the results. I was suspicious of some of my food intolerances and I was correct, as well as pointing out others. I am looking forward to starting my new eating habits so I can feel better. I highly recommend this report and the turnaround on your results is so fast.
