Theranos, the single-blooddrop lab testing company is hitting rock bottom.

Theranos was very popular with providing tests that required only a single droplet of blood with their "Edison" devices, and it has been going on for 2 years with a 9 billion dollar startup evaluation in 2014. However investigations have shown that Theranos's tests are unreliable exactly because they only measure one drop of blood.
Any and every test ever conducted by Theranos's Edison devices has been voided, and an update mail was sent to the doctors that ordered these tests, because of how many cases of wrong test results they yielded (we're talking tens of thousands of tests).

A thorough investigation will follow, which could lead to the founders of Theranos being forbidden to own or operate a medical test lab for more than two years according to California law (That's where the Theranos HQ is situated). One of the founders jumped the sinking boat earlier this month and filed a resignation, but is under investigation nonetheless.
