A method for food sensitivity panel testing (for sensitivities other than
gluten sensitivity) by detecting IgA antibodies in serum is disclosed. A
method for testing stool samples for the presence of particular
antibodies, which is more sensitive and less invasive than prior art
testing methods, is also disclosed for diagnosing immunologic food
sensitivities. These methods of diagnosis may be used alone or in
combination to further enhance the accuracy of diagnosis.
