Brunel Health Intolerance Testing

2% of the UK population have an actual allergy. Whereby, they will have an immediate reaction to a food, grain or herb. Usually, allergies are an immediate effect that can result in an airway being restricted. Intolerances are different. They can occur hours or days after eating a certain food, making it much harder to pinpoint exactly what it is that could be affecting you.

How does it work?

Blood Sample

A test kit pack can be sent to your home or collected from the clinic. To help you take your sample there is a QR code in your sample pack, scan the QR and a video will pop up explaining how to take your sample. This test can be carried out on children as young as two. Send your sample back in the post box the SAME DAY using the pre-paid postage label. Worried about taking your own sample? There is no extra charge if you make a mistake with taking your sample, we will send you a new sample kit.

If you still do not feel comfortable to take your own sample, we provide a FREE sample collection at clinic, 5 days a week.

Results - First Consultation

Within 7-10 WORKING DAYS, Don will receive your results from the LAB and will contact you by telephone to arrange your in person consultation or Zoom consultation date. This call will just be to arrange the call which will usually be within 7 days. The entire process from sample to your consultation can be 14-18 days. Within your first consultation, Don will outline a shopping list of alternatives from your local stores and recommend supplements if needed. Usually consultation take 45 minutes to 1 hour. If your results return with ZERO sensitives, which means you have not tested positive for any intolerances there will be a £100 refunded back to you - Don will still carry out a consultation to discuss and guide you on what to do now and how to move forward, this will not involve the usual 2nd consultation that is part of the original package.

Review - Second Consultation

Lastly, 6-8 weeks after your initial consultation we would ask for you to contact us again and we arrange an in person or Zoom consultation to discuss your progress and further changes you could make. Usually these consultations can take 30-45 minutes. On-going support is given during those 6-8 weeks. For example, if for some reason you did not like the texture or taste of an alternative product, Don is here to find foods and drinks you like and find tasty so that your results are sustainable. Just simply email or call Don directly, or contact us. If you need further consultations after this stage please see out nutrition page for further details.

Kind Words


We would ask you to call reception and ask to be booked in for a free 10 minutes consultation with one of our specialists. They will pick the relevant person from some of the keywords that you say. You will be given an allotted time and date (usually same day or the next working day) where one of our experts will go through the history of your symptoms, any previous medical history that may possibly be linked to this problem, what you have already done to help the area, who you potentially have already seen, then give our opinion as to whether we have experience in treating this condition/problem. We will go through roughly what we would look at if you were to come in and see us, and what to expect. If the expert you are on the phone with feels another member of the team is better suited to treating you they will refer you, should you wish to book the relevant person to book in with.


This is especially the case for Intolerance Testing – if you suffer with Rheumatoid Arthritis, IBS, Diverticulitis  or conditions involving the immune system we would suggest speaking to Don, our Gut Guru to elevate whether our pre-screening forms would need to be filled out prior to waiting for your results. As this will give us the best start in providing you with as much value at your first consultation.
