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.

Huge Demand for Food Intolerance Tests Among UK Professional Footballers

August 23, 2023

In the realm of professional sports, the pursuit of excellence extends beyond rigorous training regimens and cutting-edge equipment. The spotlight is now shining on an unexpected aspect of an athlete's preparation: their gut health. The rise in demand for food intolerance tests among professional footballers underscores the newfound awareness of the critical connection between digestive wellness and peak athletic performance.

The Intersection of Gut Health and Athletic Success

It's no secret that professional footballers push their bodies to the limits, striving for unparalleled performance on the pitch. What's lesser-known, however, is the pivotal role that gut health plays in achieving those athletic feats. A balanced gut microbiome influences an athlete's overall health, energy levels, and resilience, directly affecting their endurance, speed, and recovery.

The Impact of Gut Health on Performance:

Energy and Stamina: The foods an athlete consumes have a profound impact on energy levels. Unidentified food intolerances can lead to fatigue, sluggishness, and a lack of endurance.
Inflammation Management: Inflammation resulting from intolerant foods can hinder muscle recovery and contribute to injury susceptibility.
Mental Clarity: A healthy gut supports cognitive function, aiding in quick decision-making and maintaining focus during high-pressure matches.
Digestive Comfort: Optimal digestion ensures that vital nutrients are absorbed efficiently, promoting overall physical health.

Enter Food Intolerance Testing

As the awareness of the gut-health-performance connection grows, so does the demand for accurate tools to understand individual dietary needs. This has led to the surge in food intolerance testing among professional footballers. By identifying specific foods that may trigger intolerances, athletes can tailor their diets to optimise digestion, energy levels, and overall performance.

Supply Life: Empowering Athletes for Success

Leading the charge in this movement is Supply Life, a pioneering force in providing expert home food intolerance tests. Designed with athletes' needs in mind, these tests allow sports professionals to gain insights into their bodies from the comfort of their homes. The precision and convenience of these tests enable footballers to take control of their dietary choices, paving the way for improved gut health, athletic prowess, and overall well-being.

Conclusion

The evolution of professional sports has given rise to a new frontier: the intersection of gut health and performance. The demand for food intolerance tests among professional footballers highlights the recognition of this pivotal connection and the need for tailored dietary choices. As athletes strive for peak performance, understanding their bodies and optimising their gut health becomes paramount.

With Supply Life's home food intolerance tests, footballers can embark on a journey toward enhanced performance, setting a new standard for excellence on and off the pitch.
