Theranos engineers have created the first version of a mini-analyzer capable of working with a drop of blood. However, this device, called Edison, could do only one analysis.
However, in 2011 presented new device what was capable of performing four basic blood tests.
Edison could only do one analysis, they began using Siemens, for the other three. However, and for it it was required not a drop of blood from a finger, and a standard portion of venous blood.
Another huge problem is that last month Theranos acknowledged incorrect all the results of analyses made over the past two years. In fact, we are talking about tens of thousands of analyses. This means that on the basis of such incorrect blood tests, doctors could put thousands and thousands of incorrect diagnoses.
