Our simple steps for a full test programme
What is food intolerance?
A food intolerance is difficulty digesting certain foods and having an unpleasant physical reaction to them. As individuals, our reactions to foods and drinks vary a great deal. An ingredient which may cause problems for one person could be completely acceptable for another. The most common food intolerance symptoms are bloating and stomach pains, which usually come on a few hours after consuming the food.
How to find out if you are intolerant to foods?
At YorkTest, we like to refer to this as our personal ‘food fingerprint’. Discovering and understanding your own personal food and drink intolerances†, and the effects they have on your health and wellbeing, is important to ensuring you make the best possible choices to balance your diet.
How to test for food intolerance?
The YorkTest Premium food intolerance test kit contains all you need to take a small blood sample (2 – 3 drops) in the comfort of your own home. Simply return your sample in the pre-paid envelope provided (UK only) to our York laboratories. Our expert laboratory technicians will then analyse this for reactions to 208 food and drinks. Your confidential results and additional support material will be posted to you within 10 days.
Are blood tests for food intolerances accurate?
When you have received your results and are ready, you can contact us to book your appointment with one of our qualified nutritional therapists. These half hour sessions will provide you with support and knowledge to assist you in your new diet, ensuring you are confident in the changes you can make to improve your health and wellbeing. In our latest customer survey, 4 out of 5 customers told us that they had seen improvements in their health after following a YorkTest programme and 89% of those people did so within just one month of dietary change.

It’s common to believe that a food allergy and a food intolerance are the same thing, but they take on different processes in the body.
A food allergy can cause a life-threatening condition called anaphylaxis. This is when released chemicals act on the blood vessels to cause swelling. Food allergies normally appear instantly and up to two hours after consumption.
A food intolerance, on the other hand, may take up to three days to show any symptoms, making it problematic to identify the cause. A food intolerance is not life-threatening but can cause distressing symptoms, such as Irritable Bowel Syndrome (IBS), migraines and headaches, skin issues, tiredness and joint pain.
Suspect you may have a food allergy instead of a food intolerance? Not to worry. You can find our food allergy test here.
For more information on the difference between a food allergy and a food intolerance, click here.
This test will analyse your IgG antibody reactions to 208 food and drink ingredients. There are four different types of food-specific IgG antibodies. Unlike many of our competitors, we test the levels of all four of these to pinpoint the ingredients your body is reacting to. Learn more here.
Please note that this test will NOT pick up on the following:
- Food allergies (IgE antibodies)
- Coeliac disease
- Enzyme deficiencies, such as lactose intolerance
- Histamine sensitivity
- Chemical sensitivities
- Ingredients that are not in your diet
Once you’ve placed your order, we will send you a kit containing everything you need to supply us with a small blood sample. This involves a simple prick of the finger with a small, sterilised lancet, which you can carry out in the comfort of your own home. You then post this sample to our laboratory in the pre-paid envelope provided and we’ll do the rest!
It’s really easy to take the test, as demonstrated by the step-by-step leaflet you’ll receive in your kit and the video below:
The Food&DrinkScan Premium programme is our bestselling test and is ideal for those who are suffering with intolerance-related symptoms and would like to optimise their diet.
If you are simply curious as to whether you have a food intolerance†, we would recommend our FirstStep test, which is a simple positive/negative indicator test.
Those suffering with IBS symptoms should consider our IBS Diet Programme, an alternative to the Food&DrinkScan which tests for the same ingredients but includes post-test care tailored to IBS sufferers. Our Ideal Weight programme meanwhile is a better option for people specifically looking to change their weight by also addressing their food intolerances†.
If you are experiencing symptoms of any kind, you should always consult with your GP first before following a YorkTest programme.
Please note that we’re unable to provide this test to people who are:
- Suffering from a blood borne disease such as Hepatitis or HIV
- Pregnant or breastfeeding
- Under the age of 2 years
We are proud to say that our laboratory has a >98% reproducibility rate. This means that, on average, two separate tests carried out with the same person’s sample (taken on the same day) will correlate with each other >98% of the time.
Our laboratory is regularly audited by independent authorities, staffed by fully trained and highly qualified scientists and uses the very latest equipment and procedures to ensure the utmost accuracy.
The laboratory team is overseen by our Scientific Director, Dr Gill Hart, who has been with us since 2005. Dr Hart is a leading UK biochemist and an expert in food intolerance who is passionate about scientific innovation. She has over 30 years of experience in the development and validation of diagnostic tests and testing services.
You will receive clear, colour-coded results of your test within ten days. These will summarise the complete list of ingredients in three categories. If a food or drink appears in the green column, this means there is no reaction to that ingredient. Should it appear in the red or amber column, this means that a strong (red) or borderline (amber) IgG reaction has been detected.
Your results will arrive in a pack, which also contains a food and drink diary and a support booklet. These resources will give you lots more useful information about food intolerance and nutrition in general and the diary is ideal for recording your progress as you begin to remove your “trigger foods” from your diet.
So what happens if you test negative for food intolerance altogether? Simple. We refund the cost of your programme, minus a £25 administrative fee.
The next step once you’ve received the results is an important one on your YorkTest journey. You need to call our team to make an appointment for your first nutritional consultation. Two 30-minute telephone consultations are included in the price of your programme and they provide invaluable advice from our nutritional professionals.
Our team of nutritional therapists are there to guide you on nutritious alternatives to your “trigger foods” and answer any queries you may have about the elimination diet.
The elimination diet
We recommend that you cut out your personal “trigger foods” for 12 weeks in total, in order to give yourself the best chance of experiencing the benefits of your elimination diet. In our 2017 customer survey, 4 out of 5 customers saw improvements in their health after following a YorkTest programme.
Here at YorkTest, we understand that changing your diet can be challenging. That’s why our friendly and knowledgeable Customer Care team are always there for you to offer additional support if required. They are available to contact and offer advice six days a week, including Saturdays.
