Silicon Valley unicorn Theranos raised over $700 million from prominent investors by claiming its proprietary 'Edison' device could run hundreds of comprehensive diagnostic tests from a single finger-prick drop of blood. In reality, the miniaturized hardware suffered from catastrophic mechanical inaccuracies and could reliably perform only a tiny handful of tests. Whistleblowers Tyler Shultz and Erika Cheung exposed that lab directors diluted patient samples to run them on modified commercial Siemens analyzers while fabricating quality control data for federal regulators, culminating in federal fraud convictions for CEO Elizabeth Holmes and COO Sunny Balwani.
