If you have celiac disease, you may rely on commercial test kits for detecting gluten in food. But how reliable are these test kits for gluten detection? Dr. Joseph Murray, M.D., evaluates the ELISA test kits, based upon a study published in Cereal Chemistry.
The team of researchers who set out to evaluate the accuracy of 14 ELISA kits for gluten detection found that none of the currently available ELISA methods can accurately detect and quantify gluten in all cases. In the face of these results, Dr. Murray has the following recommendations for individuals who use the kits:
The authors of this study conclude that further improvements are urgently needed, and recommend focusing on competitive formats, improving extraction methods, and the detection of relevant gluten peptides.
