&gt; 2nd theme: lab tests from Theranos differ from generally accepted standards. How do they differ if in fact they are using the same tests as everybody else? Is it just the general variability of lab results and similar variability could be find in quest diagnostics as well?<p>Because Edison and the dilution procedure produce low quality results.  Thus for a large number of the tests Theranos is less accurate than traditional methods.<p>&gt; 3rd Theme: almost all people say Theranos is dramatically cheaper than competitors. How is that possible when they are using the same equipment as everybody else for most of the tests? Is it a process innovation in operations rather than from Edison&#x2F;better equipment tech? Or are they just subsidizing these costs and being cheaper and possible have bad unit economics?<p>The above is possible because they are not currently focused on profit, rather market share.  All that money that they have raised has had to go somewhere.
