I seem to detect the familiar odor of negative PR wafting over this entire series of articles. The New Yorker has one of the most famously rigorous fact checking policies in journalism. Things rarely ever slip past them. Companies like Quest Diagnostics and Labcorp have immense amounts of revenue to lose to a new, more efficient entrant like Theranos. No surprise they would go negative to undermine a new competitor. As far as the company ferreting out journalistic mistakes and correcting them, the onus should be on the media to get the story right.

Yes, agreed, except that micro-assay isn't new, and is actually used on newborns all the time. It isn't used in adults because it tends to be wildly inaccurate/variable, even under the best of circumstances.
