Quick answers

What was Theranos supposed to do?

The company claimed its devices could run a broad menu of clinical laboratory tests from a finger-stick or other small sample, faster and cheaper than a conventional venous draw sent to a central lab.

When did the public case break?

The Wall Street Journal published John Carreyrou’s first major investigation on 15 October 2015. CMS sanctions, SEC charges (2018), and criminal trials followed.

What was Elizabeth Holmes convicted of?

On 3 January 2022 a Northern District of California jury convicted her of conspiracy to commit wire fraud and three counts of wire fraud involving investors. She was acquitted on several other counts, including patient-related wire-fraud counts.

What sentence did she receive?

Judge Edward J. Davila sentenced Holmes on 18 November 2022 to 135 months (11 years and 3 months) in federal prison, plus supervised release and restitution to be determined in the judgment papers.

What happened to Sunny Balwani?

Ramesh Balwani was convicted in July 2022 on all twelve counts he faced, including investor and patient-related fraud, and was sentenced in December 2022 to 155 months.

Did patients receive inaccurate results?

CMS findings and trial evidence included inaccurate or unreliable results from the Newark lab. Holmes was not convicted on the patient-fraud counts; Balwani was. Civil and regulatory files address laboratory quality separately from those verdicts.

2015

The Theranos investigation in public view begins with journalism, then laboratory regulation, then securities and criminal process.

This page records those steps. It does not explain how to falsify a validation study or how to present a device that is not ready.

Agencies

What followed

  1. Source interviews

    Journal reporters interviewed former scientists and lab staff and compared their accounts with the public testing menu.

  2. Publication

    The 15 October 2015 article forced Theranos into public rebuttal and drew CMS and state attention to the Newark lab.

  3. CLIA inspection

    Surveyors reviewed quality-control records and proficiency testing; findings led to sanctions and voided results.

  4. Civil securities case

    The SEC charged fraud in 2018; Holmes settled those civil claims without admitting or denying the complaint’s allegations, on terms in the decree.

  5. Indictment and discovery

    Prosecutors obtained emails, texts, and investor materials and split the two defendants for trial.

  6. Two jury trials

    Holmes’s case ended 3 January 2022; Balwani’s ended in July 2022. Sentencing hearings closed the trial court year.

Turning points

After-the-fact investigators tested claims against laboratory records and investor decks. The science story ended when those records could not support the pitch.
