Theranos, the blood-testing start-up that recently came under fire, continued to defend its technology with a blog post on Thursday.
"From his very first interactions with Theranos, the (Wall Street Journal) 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. The articles that appeared last week are the inevitable product of that approach," the company said.
Last week, the Journal published a pair of articles suggesting the start-up was relying on technology from traditional labs as it struggled with its own proprietary technology. The articles also reported that some former employees doubt the reliability of Edison, the company's signature lab tool. The viability of Edison, which aims to test just a few drops of blood rather than a typical amount drawn from an arm, is key to Theranos's strategy.
CEO Elizabeth Holmes has defended her company through several media appearances, including on CNBC. She acknowledged that Theranos has used technology from other labs for tests from venous draws but stressed that the company relies on its own technology for finger-stick tests. She noted that Theranos has received FDA approval for one test and expects to get clearance for others.
