Food intolerance is an abnormal reaction to certain foods that manifest in a number of different ways. Our test detects potential food intolerances in which there is an immune response that produces IgG antibodies.
The mechanism of food intolerance involves the production of antibody/antigen complexes, which are deposited in tissues, triggering the release of inflammatory chemicals that may lead to damage and inflammation in that particular tissue. For example: the gut, causing IBS symptoms; in the joints, causing arthritis; in the head, causing migraines
Although not life threatening like food allergy, food intolerances should never be underestimated, as its impact on sufferers can be significant, severely impacting on their ability to live normal healthy lives. Food intolerance is extremely widespread and it is estimated that 45% of the population could be affected. Most people may suspect it is a food causing their discomfort and may try an elimination diet that can take months to determine the culprit. The food intolerance blood test is a fast and convenient way to feel better faster and improve your lifestyle.
The Health Food Intolerance Test utilizes a new, state of the art immunoassay based on microarray technology to detect food-specific IgG antibodies. Food extracts are ‘printed’ onto nitrocellulose pads on a glass microscope slide, together with calibration standards and controls for each patient. Food IgG antibodies, if present, bind to the food extracts. The bound food IgG antibodies are subsequently detected through the use of other immunoassay reagents, which generate a blue color in the presence of the food IgG antibodies. The density of this blue color is measured using a high-resolution scanner. The results generated by the scanner are then calibrated against the standards using specialized software to give quantitative results. This software then produces a tailor-made patient report of the final food IgG antibody results for each food on the requested panel.
The Health Food Intolerance test is carried out on a blood sample collected from a finger-prick into blood collection tube. The sample is stable for 14 days, allowing for transportation to our testing facility.Read More
