No – this is a food intolerance test that detects IgG reactions, which are delayed immune responses, unlike immediate IgE allergies.

Our tests are processed in a UKAS-accredited lab with 98% reproducibility.

Yes. The test components are free from animal derivatives and can be used with full confidence by Muslim users.

Muslim users.Yes, for children aged 2 and above. Please use the Junior Test.

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.

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.

Yes, food intolerance tests can be effective in identifying foods that cause adverse reactions. These tests measure IgG antibodies in your blood, which indicate sensitivity to specific foods. Independent studies and clinical practice have shown that eliminating foods identified through these tests can lead to significant symptom relief, especially for conditions like bloating, food related energy dips and others . However, it's important to interpret results with the guidance of a nutritionist / dietician.

An NHS GP's in the UK doesn't offer food intolerance testing, but verious GP's around the world do offer a blood based food intolerance test to aid symptoms. Alternatively, there are few blood based CE marked home test kits available that can be used with guidance from a nutritonist to interpret the results accurately.

The most accurate food intolerance tests are those that use blood samples to measure IgG 1,2,3 and 4 antibodies against a wide range of foods using microarray technology. ELISA-based tests are considered reliable and provide detailed insights into food sensitivities. These tests are clinically validated and widely used in medical diagnostics for their precision and reliability.

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.

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.

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.

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

FeelNoor'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.

The two most common symptoms of food intolerance are: Digestive issues (bloating, frequent or infrequent trips to the bathroom) Food related energy dips / food coma However there other many other symptoms that people have reported

A true food allergy triggers an immune system reaction that can affect multiple organs in the body, leading to a range of symptoms that can be severe or even life-threatening. In contrast, food intolerance typically results in less serious symptoms, often limited to digestive problems. Both terms relate to adverse physiological responses to particular foods, but the mechanisms differ. Reactions can be immunological (IgE or IgG mediated) or non-immunological, causing immediate (minutes to hours) or delayed (several hours to days) responses. Identifying the specific reactive mechanism is crucial for effective management and dietary interventions to prevent unpleasant or dangerous symptoms.

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.

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

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

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.

At Feel Noor, we partner with trusted laboratories, who screen for over 200+ foods and drinks to give you the most accurate, medically reliable results. It provides Comprehensive testing that protects you even from hidden/accidental exposures. Extra protection: Even if you never consume pork etc sometimes foods are cross contaminated or mislabeled. Knowing your body's response provides extra reassurance. Medical accuracy: By testing everything, the results are complete and reliable. If the panel excluded certain foods, it could reduce accuracy.
