This Woman Invented a Way to Run 30 Lab Tests on Only One Drop of Blood

Caitlin Roper:

That was a decade ago. Holmes, now 30, dropped out of Stanford and founded a company called Theranos with her tuition money. Last fall it finally introduced its radical blood-testing service in a Walgreens pharmacy near company head­quarters in Palo Alto, California. (The plan is to roll out testing centers nation­wide.) Instead of vials of blood—one for every test needed—Theranos requires only a pinprick and a drop of blood. With that they can perform hundreds of tests, from standard cholesterol checks to sophisticated genetic analyses. The results are faster, more accurate, and far cheaper than conventional methods.
 The implications are mind-blowing. With inexpensive and easy access to the infor­mation running through their veins, people will have an unprecedented window on their own health. And a new generation of diagnostic tests could allow them to head off serious afflictions from cancer to diabetes to heart disease.
