Do you [Acu-Gen] know that your test is accurate or don't you? (And by "know" I don't mean "know in your heart of hearts" so much as "know from the results of well-designed and well-conducted scientific studies with sufficiently large sample size that the results are reliable".) Pressed on whether tests of the accuracy had already been performed (as Bonelli claimed) or are currently being performed (as the Acu-Gen email to NPR suggested), the head of Acu-Gen, Chang Ming Wang, was evasive.
