Under pressure from regulators, laboratory firm Theranos Inc. has stopped collecting tiny vials of blood drawn from finger pricks for all but one of its tests, according to a person familiar with the matter, backing away from a method the company has touted as it rose to become one of Silicon Valley’s hottest startups.

Silicon Valley blood-testing startup Theranos Inc., responding to an article in the Wall Street Journal that questioned its technology, said its products and services are "accurate and reliable." The Journal article said that the company overstated the ability of its tests to accurately perform several dozen types of measurements and that Theranos relied on other companies’ equipment for many tests. While the newspaper was working on the story, Theranos removed language from its website that said, "Many of our tests require only a few drops of blood," according to the article. Theranos told the newspaper it made those changes for marketing accuracy. (Mittleman, 10/15)

Theranos, the secretive and revolutionary bloodwork analysis start-up valued at $9 billion, is under fire from a Wall Street Journal report that anonymously quotes former employees who question the efficacy and accuracy of the company's proprietary hardware. The heart of the allegations charge that of the 240 different tests Theranos offers consumers, only 15 are conducted on a machine called Edison while the rest are being outsourced to machines that are similar to those used by more traditional labs such as LabCorp and Quest Diagnostics.
