The latest FDA attack, focuses on genetic testing...which essentially involves spitting on a piece of paper and spending a hundred bucks.
It doesn't sound like they're arguing the accuracy of the tests, but that the American people are too stupid to make any sense of the results, and it requires government intervention.
Personally, I don't see this as being any of the FDAs business. If the company is committing fraud, (which they aren't), it's a criminal matter for the FBI to handle.
