Nutriscan is the only clinically predictable diagnostic test for dogs, cats and horses to identify the commonly seen food intolerances and sensitivities in saliva. It is not a test for the rarely seen true allergies to foods. The Nutriscan test is patent protected in the United States and internationally.
By contrast, swabs alone do not generate sufficient biological fluid to quantitatively determine specific food reactivities. Simple positive or negative results, for instance from tissue swabs, do not provide information about the specificity or sensitivity of the assays used. Therefore, selection of foods based upon this type of information is medically and scientifically unreliable.
