To support your overall health, we recommend following an elimination diet for 6–8 weeks. During this time, completely remove the foods identified as potential intolerances from your diet. This allows your digestive system and immune response to reduce inflammation and regain optimal function.

After this elimination phase, gradually reintroduce the excluded foods one at a time, in small amounts, while observing any signs of sensitivity or discomfort.

To ensure you’re still meeting your nutritional needs during this process, we recommend following our dietary guidelines to help maintain a balanced, nutrient-rich diet.

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.

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.

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 place them into a small plastic bag, put them in an envelope along with a completed form (instructions are emailed post order).

No, we test the composition of the hair sample, so the hair dye will not affect your test results.

Only a small amount; 5 individual strands. We don’t require clumps of hair.

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.

Unfortunately, we don’t recommend the test for anyone below the age of 6. Younger children have not yet built up their tolerance levels, and this can give false results in the lab.

Yes. 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.

All intolerance tests are processed in the UK. Results are emailed typically within 72 hours upon receipt of your hair sample.

Tests can be easily ordered on our website. Should you have further questions, please don’t hesitate to email us.

Here at UK Food Intolerance our main goal is to help people live a healthier and happier lifestyle. Therefore, we don’t see any value in overcharging for our tests. We are here to help you help yourself!

Your order number will be clearly stated on your order confirmation email that you will have received when you made the initial purchase.

All samples received on behalf of UK Food Intolerance will be disposed of via a clinical waste unit. Therefore, all samples will be used once for their sole purpose of testing, once the test is complete all samples will be immediately disposed of.
