Our simple steps for a full test programme
Our Ideal Weight Programme combines IgG antibody testing to 208 foods and drinks with tailored advice and support from our qualified nutritional therapists.

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
If you have already taken the decision to eliminate a particular food or foods from your diet in the last six weeks, they may not show up as a reaction on your results. If you know of foods that cause you to feel unwell, do not start eating them. We do not encourage you to eat foods which you already know are a problem for you.
The Premium Programme will test your IgG reactions to our complete range of 208 ingredients.
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 Ideal Weight Programme is perfect for those who are looking to change their weight by discovering their trigger foods and following a personalised low GI diet plan.
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, which tests 208 food and drink ingredients and includes post-test care tailored to IBS sufferers.
Our most popular food intolerance programme is the Food&DrinkScan Premium, which tests for a total of 208 food and drink ingredients and offers a best value option.
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 18 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, a 7 Day Low GI Kick Start Plan, a support booklet and a food intolerance ID card (ideal for showing your waiter when dining out). These resources will give you lots more useful information about food intolerance and nutrition in general. The diary is ideal for recording your progress as you personalise your low GI plan with your individual trigger foods.
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 a nutritional professional.
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 or the low glycemic index. As an additional feature for the Ideal Weight Premium Programme, you will also be provided with a 7 Day Low GI Kick Start Plan. This handy book of low GI recipes has been compiled by renowned nutritional therapist, Alli Godbold.
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. With the support of our nutritional therapists, you should also consider introducing some more low GI foods into your diet, to help you feel fuller for longer.
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.
The glycemix index (GI) is a rating system for foods containing carbohydrates. It shows how quickly each food affects your blood sugar (glucose) level when that food is eaten on its own.
With high GI foods, carbohydrates are broken down quickly by your body and cause a rapid increase in blood sugar.
Low or medium GI foods are broken down more slowly and cause a gradual rise in blood sugar levels over time. They make us feel fuller for longer and less hungry, and are more nutritionally balanced.

^ Foods and drinks that have a low GI make us feel satisfied for longer and less hungry, they are more nutritionally balanced. Low GI diets have been proven to break the vicious circle that other diets produce of losing weight and then putting it all back on.
