Test Type: Kit Based - serum

Overview:

Many chronic conditions - from IBS and digestive problems to migraines to depression and mood disorders - may be indicators of food sensitivity. Common offenders include dairy and gluten, but food sensitivities can be complex and difficult to pinpoint. In many cases, a less obvious source may be causing or contributing to a patient’s symptoms.

Our 240 Food Panel offers comprehensive testing to identify food sensitivities to both common and less prevalent offenders that, in some cases, a patient may not even realize are in his or her diet. It is an ideal choice for patients who eat a broad range of foods and cuisines. Once identified, trigger foods can be controlled to relieve symptoms and help patients lead their healthiest lives.

Testing Process

Our panel is a quantitative ELISA analysis of specific IgG, IgG4, and IgA antibodies to 240 common foods and spices.

Specimens are tested in duplicate on the ELISA platform. We follow a diligent process to extract the key component from each analyte to ensure the antibody present in the patient's serum will bind to it, and validate with positive and negative controls. The IgG and/or IgA antibodies, once bound to antigen, are detected through spectrophotometric analysis wherein the values are directly proportional to the concentration of the analytes in the sample.
