Bad Blood

John Carreyrou

Bad Blood follows Theranos from Elizabeth Holmes’s promise of painless, small-sample blood testing to its collapse under technical failures, secrecy, intimidation, and investigative scrutiny. It asks how a persuasive mission and prestigious backing displaced verification—and why medical technology demands stronger evidence than ordinary startup hype.
