I feel like the luckiest person in the world because I get to live every single day knowing

that even in a small way I've done something that's made someone's life better.

Except Elizabeth Holmes wasn't making people's lives better.

The young entrepreneur who dropped out of Stanford to revolutionize blood testing with her

company Theranos, she was actually making a lot of people's lives worse.

Which is what I was trying to get to the bottom of on June 23rd, 2015, when I entered a conference

room at the offices of my employer, the Wall Street Journal in Midtown Manhattan.

I was hoping to get Elizabeth to finally answer some of the questions I'd been asking for

two months after receiving a tip that her science was on sound.

It was like, how many tests can you really run on a drop of blood?

I knew what she'd been claiming in public.

Theranos could run comprehensive laboratory tests from a tiny sample or a few drops of blood

that could be taken from a finger.

But I had multiple sources who said that wasn't true.

Unfortunately, Elizabeth wasn't there that day to answer my questions.

Instead, she'd sent a subordinate named Daniel Young, laboratory director for our Phoenix

laboratory.

Okay, so you have clear certification to sign off on patient results?

We looked nervous and coached and lawyers.

Lawyers who every time I asked Daniel a question answered for him.

Maybe do you want to describe yourself kind of what you do there?

Or interrupt it.
