Theranos: Science Fact or Science Fiction?

There’s been a lot of buzz around the enigmatic health startup Theranos. The company’s disruptive diagnostic technology is designed with the aim of completely changing the way patients access sampling and testing, with plans to create a system whereby one fingerprick can be cheaply used for dozens of tests. And, as we’ve reported previously (1), the company has been cleared by the FDA to market its herpes simplex test in the US, and received a waiver which means the test can be used outside of traditional lab settings. Despite the fact that the company is still to release any details of their testing equipment, or to publish any peer-reviewed data (2), Theranos has garnered a huge amount of attention.

But a scathing article recently published in the Wall Street Journal (WSJ) (3), has levelled several accusations against the company, claiming its revolutionary testing methods are inaccurate, and its success overhyped. A recent FDA inspection of Theranos also made the news when the resulting report contained mentions of the company’s “nanotainer” tube technology being listed incorrectly (4), with the report stating, “You are currently shipping this uncleared medical device in interstate commerce, between California, Arizona, and Pennsylvania.”

An official statement released by the company (5) addressed and refuted all of the claims made by the WSJ – but without producing any data or other details on the accuracy of their testing systems. The statement also criticized the reporter responsible for the story, claiming that, “From his very first interactions with Theranos, the reporter made abundantly clear that he considered Theranos to be a target to be taken down, and not simply the subject of an objective news story.”

Since releasing the statement, the company has announced its intentions to release data comparing its technology to reference testing methods, although when and where this will happen remains unclear (6). CEO Elizabeth Holmes, hailed by some as a diagnostic wunderkind (7), has also hit back at critics, saying “This is what happens when you work to change things. First they think you’re crazy, and then they fight you, and then all of a sudden you change the world” (8).

So is Theranos set to transform diagnostics, or have the tales of its technology been greatly exaggerated? The debate rages on.
