Are they reliable? How reliable?

Are they reliable? How reliable? Karyn Seroussi on Lab Reliability:
"I don't think anyone I know in this business is 'preying on vulnerable parents,' but I do believe that the current technology is not up to the task of consistently and reliably identifying these peptides, since they are unstable and tend to degrade after collection. At best, the tests seem to be giving some parents the push to start the diet (many or most of them need to anyway), and at worst, they are giving misleading results. For some people, the test seems to have been useful as a guideline -- it's an individual choice whether to have it done. I have never advocated the peptide testing. I have always maintained, as in my book, that the best test is a trial on the diet. I cannot fathom why parents would wait even a day for test results when they could be implementing this diet, based on the pretty good odds that it will make a difference."
