Test results can be misused?

How does on misuse information? This doctor was actually making an argument in favor of ignorance (and in this day and age of doctors stereotypically ordering hundreds of tests, none of which apparently come with the worry of misuse).

Information is not a bad thing to have. Ignorance (lack of knowledge) is the thing most likely to be misused, such as the way that doctor attempted to misuse the ignorance about the antibodies to sell a product in which she has a financial incentive.
