What is Urinary Peptide Testing?
By collecting urine samples, storing them frozen, and examining them using mass spectrometry, HPLC, or RA methods, certain opiates such as casomorphin can be detected in levels higher than those found in normals. Such results would indicate the necessity of implementing a GF/CF diet. However, there is still some debate as to the accuracy and consistency of these test results. From Paul Shattock: “Certain biologically active peptides derived mainly from gluten and/or casein in the diet are not broken down correctly, and through problems with the permeability of the gut, are present in the blood in much greater quantities than would normally be expected.
