You can’t help but have noticed that many of the links in this post are to articles on Quackwatch. That’s because the site is chock full of useful information about bogus tests, far more than can be found elsewhere. There you will find a more comprehensive list of bogus tests than I’ve mentioned here, and a larger list of laboratories peddling them. You’ll also find an article on “Dubious Genetic Testing” co-authored by the Quackwatch founder, Stephen Barrett, and our own Harriet Hall, and an article about bogus “biomedical treatments” for autism showing that—surprise!—Doctor’s Data and Genova Diagnostics are major players there, too.
I stand by all of those statements. It turns out that Doctor’s Data is not pleased that Dr. Barrett has so thoroughly blown the company’s cover.
