The IgG ELISA Food Intolerance Test
Better Control of Health's IgG ELISA Food Intolerance Test utilizes the ELISA (Enzyme Linked Immunosorbent Assay) method to detect circulating Immunoglobulin G (IgG) antibodies which recognize and bind to food antigens.
The ELISA method is used extensively in immunology and biochemistry. The technique has been shown to be reliable and reproducible in detecting a variety of antibodies and antigens of clinical importance.
In the ELISA method, food antigens are immobilized on to the surface of polystyrene micro-titre plates. To protect the unstable antigens, the micro-wells are then further coated with a stabilizing polymer layer, which is dried on top of the food antigens. Additionally, our food extracts are obtained from FDA approved sources to ensure the highest quality extracts and lot-to-lot reproducibility. The coating levels of the extracts have been optimized for sensitivity to ensure the reactions identified are real rather than false positive reactions (something which plagues other competing tests).
The measurement of food antibody levels depends on the ability of the patient's food antibodies to attach themselves specifically to the food antigen. After the antibody has bound to the antigen, the micro-titre plates are rinsed to remove other antibodies and blood constituents. The food antibodies are then detected using a second antibody which is chemically tagged with an enzyme. The enzyme causes a color to develop at the end of the process. The color density obtained is an accurate indication of the original anti-food antibody concentration in the patients blood sample.
The color produced by calibrated antibody reference standards is compared with the patient's result, allowing the laboratory to accurately estimate the amount of each food antibody. The laboratory then interprets the results and places each food in the relevant category of "no reaction", "rotate" or "avoid". A positive control sample is always included in each test to confirm that the assay system is working correctly.
The "Finger-Stick" Method
Just as different facilities have different qualities of tests, so do they have different specimen requirements. Some laboratories in the food intolerance industry require 1-3 full tubes of whole blood while others might require as little as less than 1cc of a blood specimen.
Better Control of Health made the painstaking effort to introduce to the USA the IgG ELISA food intolerance "finger-stick" technology in the late 1990's, which is now recognized internationally. Here is how it works

* Note: Please fully review the illustrated, step-by-step instructions included in the kit before performing the above steps. Also, postage-paid return mailers are only provided for specimens being shipped within the United States. The cost for shipping specimens from outside the outside the United States will be the responsibility of the shipper.
All that is now left to do is to have your local postal service deliver your specimen. Once your specimen has been processed, the results will be sent directly to you along with your Optimum Health Resource Guidebook. Additionally, anyone whose specimen is screened through our facility for IgG-mediated food allergy (food intolerance) is provided 12 months of complimentary telephone and email support at no additional cost!
