A doc have to wonder between the malpractice and overuse. The decision has to be evidence based. In reality, this is not always easy, especially for family docs who have to rely on the testing results from a big hospital or company that will arrive in 2-3 business days.

I was given some potent antibiotics from the surgeon for my infected wounds after an op without a culture for specific bacteria. fortunately it was a right antibiotics after my docs called that guy to do a culture.
