Method for diagnosing immunologic food sensitivity

Abstract

The invention includes novel methodology for diagnosing immunologic food or drug sensitivities. A method for diagnosing food sensitivities includes using diagnoses of other related disorders as indicators in the diagnosis of the food sensitivity. Additionally, failure to respond to or a relapse after treatment for microscopic colitis with bismuth subsalicylate is disclosed as being a further indicator in the diagnosis of immunologic food sensitivity. Finally, the presence of certain HLA-DQ alleles, particularly HLA-DQ1,1; -DQ1,3; -DQ1,7; -DQ1,8; and -DQ1,9 as indicators in diagnosing immunologic food sensitivity is also disclosed by the invention. A method for food sensitivity panel testing (for sensitivities other than gluten sensitivity) by detecting IgA antibodies in serum is also disclosed. A method for testing stool samples for the presence of particular antibodies is also disclosed for diagnosing immunologic food sensitivities. These methods of diagnosis may be used alone or in combination to further enhance accuracy of diagnosis.
