Memorable quotes from Mike Drues:

“Even from a technology perspective, the technology of these LDTs is becoming much much more complicated.”

“Long story short, I think Theranos took a fairly liberal interpretation of the words surrounding the LDT.”

“I’m a biomedical engineer first and a regulatory consultant second. And that’s the order we should think about these things.”

“Even though I’m a regulatory consultant, I’m not a fan of creating new regulation.”
