Theranos doesn't have anything behind it - this company needs to go away and return its money to its investors. A single drop of blood is far too little to provide an accurate representation of your own blood components, the blood that's gathered from a fingerprick might end up containing a much higher or much lower concentration of 'x' than the rest of your blood. It's why traditional blood tests gather much larger amounts of blood - to increase the sample size.
