What is the test method?

Our food intolerance tests are done using a blood based method covering IgG 1,2,3,4, the blood sample collection process is done via a pin prick to the finger, it takes around 4-5 large droplets.

Why do food cause an IgGantibodies response?

Generally, foods are broken down during digestion into their component parts e.g. amino acids, glycerides etc. These pass harmlessly through the gut as the gut becomes inflamed (bloated) these proteins enter the bloodstream. This is where they are recognized by the immune system as being ‘foreign’. The immune system responds by making IgG antibodies to these foods.

What is the difference between hair and blood based test?

You can't test immune reactions via a hair sample, and in many cases there have been discrepancies in results when parts of the hair have been coloured/bleached. This has led to inconsistency in the sample tested twice. Our IgG 1,2,3,4 blood based testing covers the full range of antibodies responses, this is important, if a particular food elevates any antibodies against it, this means your gut and immune system recognises that food as a threat. This could affect the nutrients absorbed from this particular food and leads to multiple symptoms.

Do high IgG antibody levels cause symptoms?

When a food causes the body to produce high levels of IgG then these antibodies combine with the protein in the food to form an ‘antigen-antibody complex’. These complexes are usually eliminated by other cells in the immune system. However, if the immune system is overloaded, these insoluble molecules become deposited in tissues within the body, causing chronic inflammation and the subsequent production of symptoms.

Why test for IgG antibodies to foods?

The efficacy of a diet based on the measurement of IgG antibodies specific for food components has been demonstrated in a number of conditions, both in independent studies and clinical practice. Excellent results have been obtained in patients with migraine, IBS and obesity.

What is the lower age limit for testing?

Supply Life's existing policy for a lower age limit on testing for IgG food antibodies is that we do not recommend testing on children under the age of 2 years. We base this on the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition Guidelines for the Diagnosis of Coeliac Disease 2012, which states that there is a possibility of false negative results occurring in infants younger than 2 years of age. This related to the fact that the infant gut is more permeable than that of an adult coupled with immature mucosal immunity that is still in the learning and development stage. We have used this criterion as antibody measurements in Coeliac Disease are comparable to food IgG measurements used in our food intolerance tests. However, we are aware that there are in fact no published guidelines that specifically indicate a minimum age for testing for such IgG antibodies, for example the guidelines for testing for coeliac antibodies indicate that such testing can be performed any time after the introduction of gluten into the diet. Therefore, where such requests are received from a statutory regulated professional the decision of when and what tests to perform will remain the responsibility of the requesting clinician.

What should be considered before testing - Is there any medication that I should avoid when taking a food intolerance test, due to its potential effects upon the results?

Customers should avoid the use of immunosuppressant medication if possible if performing these tests, as they may have an impact upon the results. Please refer to the medication datasheet in the “Support” section for further details.

How does the test work?

Food extracts are 'printed' onto nitrocellulose 'pads'™ on a glass microscope slide, together with calibration standards and controls. A blood sample provided by the patient is diluted and dispensed onto each printed microarray. Food IgG antibodies, if present, bind to the food extracts and the results are measured by a high-resolution scanner, before being calibrated against the standards using the reporting software to give quantitative results. This software then produces a tailor-made printout of the final food IgG antibody result for each food on the requested food panel.

Do you need to full the microvette all the way to the white line?

Although it is advisable to completely fill the tube, a half filled microvette tube should be enough to run the test. If there are any problems with a sample and the lab will let the customer know. However, if you are ordering two tests we can test from one sample if you provide a full microvette.

Do you need to store the blood in the fridge, if not sending the same day?

Yes, it does need to be stored in the fridge with the lid secured if not sending on the same day.

Can I upgrade my test to a larger food panel?

You can upgrade for up to a maximum of 4 weeks from the date that your first sample is received.

What are the sample requirements and test turnaround?

A pin-prick blood sample is required. Results are available within 10 working days.

Does the Supply Life test for all subclasses of IgG antibody or only IgG4?

Our process screens for all IgG subclasses 1-4, with the numbers on the test report representing the total IgG concentration for each food extract in the selected panel.

Home Food Intolerance Tests: Our Three Options

October 26, 2021

Here at Supply Life, we specialise in the supply of home food intolerance tests, providing our ever-expanding customer base with a rapid, professional testing facility. Unlike many other food intolerance test providers, we understand the need to offer tailored solutions. This is because no two food intolerances are the same, with everyone experiencing different symptoms, both physically and mentally. This is why we have launched a range of test options for customers to choose from.

What is a food intolerance?

A food intolerance is when the body has difficulty digesting certain foods. The reaction to the food can be unpleasant for individuals. Reactions can include vomiting, headaches, bloating, stomach pain, heartburn and nasal congestion. While food intolerances are not renowned for causing long term damage, research shows that intolerances can affect the small intestine if not addressed. They can also have a hugely detrimental impact on one’s mood, making sufferers feel stressed and lethargic as they are not absorbing the nutrients they need from their food.

Common food intolerances

Lactose Intolerance: Lactose is a sugar found in cow’s milk. Lactose intolerance is a common food sensitivity. According to data from various research projects, 70% of UK adults are lactose intolerant. Those with an intolerance to lactose can experience many ailments when consuming lactose products. These include increased gas, bloating, nausea, loose stools and abdominal pain. Milk, yogurt, butter, cream, cheese and ice cream are common foods that include lactose.

Non-celiac Gluten Sensitivity (NCGS): NCGS is marked by the body’s immune response to gluten and wheat. Unlike celiac disease, Non-celiac Gluten Sensitivity does not see the body’s immune system attack itself when gluten is consumed. Signs and symptoms include bloating, gas, stomach pain, diarrhoea, headaches, joint pain, nausea, constipation and numbness of the limbs. Common sources of gluten include beer, bran, couscous, bread and rye.

Irritable Bowel Syndrome (IBS): Most people with IBS have a food intolerance. IBS is a common digestive system condition that affects the large intestine. Diarrhoea, constipation, gas and bloating are common IBS symptoms.
