You'd be amazed at the seemingly minor misrepresentations that a federal prosecutor can turn into a fraud case. That said, whether or not it gets that far depends entirely on the how the investors feel about it, exactly what they were told, whether they choose to report it as a crime to the FBI, etc.

I wouldn't be too sure about that. Investor fraud isn't the only thing we're talking about here. There are questions about the accuracy of the blood tests themselves.
