Quiz — Test Your Understanding

Question 1 of 7
What was Elizabeth Holmes' original concept for Theranos before pivoting to the 'Edison' machine?
  • A. A wearable patch that tested blood over the course of a day using microneedles.
  • B. A smartphone application that analyzed blood droplets placed on the camera lens.
  • C. A massive centralized laboratory that could process thousands of traditional blood vials an hour.
  • D. A pill-sized camera that patients swallowed to monitor internal blood chemistry.
Question 2 of 7
Why was relying on a single pinprick of blood a major technical flaw for the Edison machine?
  • A. The microchambers inside the Edison required whole blood, not the plasma obtained from a pinprick.
  • B. Pinprick blood coagulates too rapidly for the machine's sensors to detect chemical markers.
  • C. The FDA explicitly bans the use of capillary blood for any diagnostic testing.
  • D. The tiny sample size required severe dilution, which cast doubt on the reliability of the results.
Question 3 of 7
How did Theranos apply Larry Ellison's software business model to their medical device company?
  • A. By open-sourcing their blood-testing technology to encourage global collaboration.
  • B. By releasing a buggy product to market with the intention of perfecting it later during beta-testing.
  • C. By offering the Edison machines for free and charging a monthly subscription for data storage.
  • D. By selling direct-to-consumer online rather than partnering with established pharmacies.
Question 4 of 7
How did Theranos initially attempt to avoid FDA regulation for the Edison machine?
  • A. By claiming the device was simply a tool for sending information to Palo Alto, not a medical device.
  • B. By conducting all of their clinical trials in international waters outside US jurisdiction.
  • C. By classifying the machine as a veterinary tool rather than a human diagnostic device.
  • D. By registering as a wellness lifestyle brand rather than a healthcare provider.
Question 5 of 7
What deceptive practice did Theranos use when VIPs and investors came to see a demonstration of the Edison?
  • A. They showed an animated simulation on a screen instead of using a physical machine.
  • B. They spiked the blood samples with synthetic chemicals to ensure the machine read the correct results.
  • C. They put the blood in the Edison for show, but secretly processed the sample in a third-party Siemens machine.
  • D. They only demonstrated the machine on themselves to avoid liability for incorrect VIP results.
Question 6 of 7
What cynical strategy did Theranos use to prevent internal whistleblowing and maintain secrecy among its staff?
  • A. They paid their employees millions of dollars in hush money upon their resignation.
  • B. They systematically hired workers dependent on their visas, who were less likely to speak out due to fear of deportation.
  • C. They required all employees to live in a closed corporate campus with monitored communications.
  • D. They threatened to sue the families of any employee who spoke to the press.
Question 7 of 7
What was the tragic outcome of Theranos' policy of policing internal dissent?
  • A. A patient died from a misdiagnosed heart attack after receiving an incorrect Edison test result.
  • B. The company's lab director, Alan Beams, was wrongfully imprisoned for corporate espionage.
  • C. Sunny Balwani was deported to India after his visa expired due to an internal HR leak.
  • D. Ian Gibbons, a British biochemist who questioned the company's honesty, committed suicide after being demoted.
