Fortunately for people seeking food allergy testing, food allergies are medically testable since there is an involvement of the immune system while a food intolerance may still exist but have all negative test results. Allergy testing of immunoglobulins which are antibodies that may be found in the body is one example of allergy testing. There are different immunoglobulins and they are usually written as IgA, IgG, IgM, IgE, and IgD with IgE levels being considered the most for people with allergies.
ALCAT testing is offered by a company called Cell Systems Corporation in Deerfield Beach, Florida. ALCAT is purported to test a person’s blood for reactions to over 350 food substances. As with other methods of this type there is a segment of those who say that it works and those who say it does not work. The testing at the time of this writing begins at $425.00.
Skin testing involves taking an amount of the suspected allergen and either scratching the skin with it, injecting a little bit just under the skin or applying a patch with the allergen on the skin. Testing such as scratch testing usually involves testing a bunch of common allergens on the skin at once. The medical personnel applying the allergens keep track of which allergen is put where on the skin. After anywhere from 15 minutes to 48 hours later the area where the allergens were placed is visually examined. Reactions to any of the allergens are determined by a medical professional.
Skin biopsies are performed when there are symptoms that are involving the skin. Most think that a biopsy would be for cancer, but there are other times that it is prudent as well. A skin biopsy is when a medical professional either shaves off a tiny section of skin, takes a tiny core sample of skin, or cuts out a small part of skin to assay by testing. The sample is tested for antibodies and is examined microscopically.
The elimination diet is non-invasive but requires the sufferer to one-hundred percent commit to the elimination of ingesting, or in the case of sever allergies even coming in contact with, the suspected allergen. Since processed foods contain so many ingredients, and since the Standard American Diet (SAD) contains so many processed foods, the elimination diet may be the hardest for the sufferer to endure.
